Security in Plone Sites

by Alex Clark | July 2010 | Open Source

While Plone is quite fortunate to be built on top of the very safe and secure Zope 2 application server, there is always more we can do to make sure our site is running as safely and securely as possible.

Because security is such a big topic, there are many areas where we can perform audits and make improvements such as operating system (OS), flesystem (FS), through the web (TTW), and so on.

Lastly, there are some miscellaneous tasks that fall under the security umbrella; we can take this opportunity to learn them.

So let's get to it.

In this article by Alex Clark, author of Plone 3.3 Site Administration you will learn:

  • Restricting TCP/IP access to localhost or LAN host
  • Managing IP addresses and ports effectively
  • Configuring the Zope 2 effective user dynamically
  • Installing Cassandra to audit through the web (TTW) security
  • Applying security and bug fixes to Plone

SELinux - Highly Secured Web Hosting for Python-based Web Applications

by Joshua Kramer | May 2008 | Linux Servers Networking & Telephony Open Source

Traditionally, web hosts have had a difficult time offering efficient, highly secure web space for a multitude of customers. Generally, a host will provide cheap accounts on a shared server and offer virtual machines as a more expensive option for the more security-conscious site owners. In this article, Joshua Kramer will explain how to provide highly secure hosting for Python-based web applications in an efficient manner. With the popularity of applications such as Trac, Django, and TurboGears, Python-based web applications will become more prevalent in the future, and the concepts presented in this article will become more valuable.

Server Configuration Tuning in PostgreSQL

by Gregory Smith | October 2010 | Open Source

The main tunable settings for PostgreSQL are in a plain text file named postgresql.conf that's located at the base of the database directory structure. This will often be where $PGDATA is set to on UNIX-like systems, making the file $PGDATA/postgresql.conf on those platforms.

This article by Gregory Smith, author of PostgreSQL 9.0 High Performance, mirrors the general format of the official documentation's look at these parameters at However, it is more focused on guidelines for setting the most important values, from the perspective of someone interested in performance tuning, rather than describing the meaning of every parameter. This should be considered a supplement to rather than a complete replacement for the extensive material in the manual.

Service Chaining

by Prabath Siriwardena | October 2013 | Open Source

This article by Prabath Siriwardena, the author of Enterprise Integration with WSO2 ESB, helps you gain knowledge about Service Chaining. The Enterprise Service Bus(ESB) today serves as a key component in most of the enterprise grade deployments. In most cases the ESB removes point-to-point dependencies in your system to build a highly scalable and loosely coupled solution. But that does not necessarily mean ESB means SOA. ESB is a key ingredient to build an SOA infrastructure, but it's not a must. Even with an ESB if not followed industry best practices and patterns you will end up with a mess.

Service Oriented Java Business Integration - What's & Why's

by Binildas A. Christudas | April 2008 | BPEL SOA Web Services Java Open Source

Many of you as (Java) programmers generate business purpose code, like "confirming an order" or "find available products". At times, you may also want to connect to external systems and services, since your application in isolation alone will not provide you the required functionality. When the number of such connections increases, you would be generating more and more of "integration code", mixed along with your business code.

In this short article, Binildas A. Christudas introduces the Java Business Integration (JBI) specification and discusses how it is covered in his new book, Service Oriented Java Business Integration

Service Versioning in SOA

by Todd Biske | December 2008 | Architecture & Analysis BPEL SOA

SOA governance is the combination of people, policies, and processes within your organization that will ensure that the desired behaviors of your strategic SOA initiative are achieved.It includes the traditional areas associated with IT Governance, which is the selection and funding of IT projects. These projects define the initial scope for technology utilization and can either help or hinder the SOA effort, based upon the scope chosen. In this article by Todd Biske we will see that the SOA effort only gets executed through projects, and if the execution is poor, the SOA effort will be poor. Therefore, the project governance activities of an organization must be adjusted to include policies associated with achieving the desired behaviors associated with SOA adoption.

Advasco had initial success with their Customer Information Service and then opened the flood gates for development by the rest of the organization. These efforts were successfully reigned in by the newly formed Center of Excellence. Now, the team at Advasco faces a new challenge: modifying an existing service to handle the needs of a new consumer. This article will go over the challenges faced by the team and then present guidance for handling this situation within your own organization.

In this article by Sébastien Armand, the author of the book Extending Symfony2 Web Application Framework, has discussed about the basics of services in the Symfony2 framework. A service is an essential and core concept in Symfony2. In fact, most of the framework itself is just a big set of predefined services that are ready to use. As an example, if you just set up a new installation of Symfony2, from your project root, you can type php app/console container:debug to see the full list of services currently defined in your application. As you can see, even before we start writing anything for our application, we already have almost 200 services defined. The php app/console container:debug <service_name> command will provide information about a specific service and will be a useful command to refer to throughout the article.

Sessions and Users in PHP 5 CMS

by Martin Brampton | August 2010 | Content Management Open Source PHP Web Development

In this article, by Martin Brampton author of PHP 5 CMS Framework Development, we get into the detailed questions involved in providing continuity for people using our websites. Almost any framework to support web content needs to handle this issue robustly, and efficiently. In this article, we will look at the need for sessions, and the PHP mechanism that makes them work. There are security issues to be handled, as sessions are a well known source of vulnerabilities. Search engine bots can take an alarmingly large portion of your site bandwidth, and special techniques can be used to minimize their impact on session handling. Actual mechanisms for handling sessions are provided. Session data has to be stored somewhere, and it is better to take charge of this task rather than leave it to PHP. A simple but fully effective session data handler is developed using database storage.
