Even though a trixbox system is a phone system, it is still a basic computer system like any other. One of the problems that we face is that extensions and VoIP service providers typically come into the system over the open Internet; this means that certain aspects of our system are wide open to the outside world. During the week that this article was written, several new scripts came out that allowed people to scan machines over the Internet, find systems that are running Asterisk, get the list of available extensions, and then hack the passwords. These tools allow a malicious hacker to get into your system and start making long-distance phone calls. There were numerous instances of companies with phone bills reaching into the thousands and even tens of thousands of dollars. Because of issues like this, it is more imperative than ever that you understand how to properly secure your trixbox server from the outside world. In this article by Kerry Garrison, we will focus on how to secure the trixbox server.Read Securing Your trixbox Server in full

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

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.Read SELinux - Highly Secured Web Hosting for Python-based Web Applications in full

In order to make our site successful, we need to attract and retain site visitors. SEO is a method of site analysis and best practices for building web pages that are easily discovered and indexed by search engines. SEO is used to make our content more relevant and easily read by search engines and their crawling and indexing software. Successful SEO makes it easier for both existing and potential customers to find your website. Fundamentally, SEO is about having your URL added to a search provider's database and appearing favorably in their search results. Well executed SEO is a process of making reasonable ongoing assumptions, following consistent practices, and includes continual site review and changes. SEO is constantly evolving and best practices are a big part. In this article by Thom Robbins, author of Kentico CMS 5 Website Development, let's look at some of the best practices that you can use when managing your site.Read SEO with Kentico CMS 5 in full
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 http://www.postgresql.org/docs/current/static/runtime-config.html. 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.Read Server Configuration Tuning in PostgreSQL in full

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.Read Service Chaining in full
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 IntegrationRead Service Oriented Java Business Integration - What's & Why's in full
