Six tips for Linux, open source desktop migrations

              Planning a migration from Windows PCs to Linux-based desktops is no small task. Here are six issues and strategies to consider before getting started.
 

Securing a RADIUS server

              For any corporate wireless infrastructure to remain secure, using 802.1X for authentication is a must - after all, it provides much more granular control of authentication credentials and can provide accounting for wireless LAN usage. Setting everything up can be a complex process fraught with choosing the right EAP type that both your clients and your RADIUS server supports in addition to putting in place the PKI infrastructure that some EAP types require. During this whole process one thing can often be overlooked - the security of the RADIUS server itself.
 

Data leakage prevention: Port dependence dangers

How to build a better Web site

             The Internet has brought a lot of business to My1Stop, a Kansas, U.S.-based printing company. About half of its $US20 million in annual revenue comes from Web traffic, says Michael Joseph, vice president of e-commerce.

            Given those figures, My1Stop can't afford anything less than a top-notch site. And although it won a 2006 Web Marketing Association award for outstanding achievement in Web site development, its workers know that's not what drives business.

Prepare your network for VOIP

        Companies wanting to get the most use of voice over IP (VOIP) need to know the steps involved in hardening their network and Internet infrastructure to get the best results out of their digital voice deployment projects.
 

Kernel space: timerfd() and system call review

              One of the fundamental principles of Linux kernel development is that user-space interfaces are set in stone. Once an API has been made available to user space, it must, for all practical purposes, be supported (without breaking applications) indefinitely. There have been times when this rule has been broken, but, even in the areas known for trouble (sysfs, for example), the number of times that the user-space API has been broken has remained relatively small.
 

Mass hack infects tens of thousands of sites

              Tens of thousands of Web sites have been compromised by an automated SQL injection attack, and although some have been cleaned, others continue to serve visitors a malicious script that tries to hijack their PCs using multiple exploits, security experts said this weekend.
