Enhancing kernel security with grsecurity

Filed under
HowTos

Is your server as secure as it could be? Sure, you use a firewall, mandate strong passwords, and patch regularly. You even take a proactive approach by performing security audits with tools such as nmap and Nessus. Yet you may still be vulnerable to zero-day exploits and privilege escalation attacks. If these possibilities keep you awake at night, you're not alone. The sleepless folks with the grsecurity project have developed an easy-to-use set of security enhancements to help put your fears to rest.

To say that grsecurity provides many enhancements is an understatement. There are more than 30 options to choose from after installation.

Take note that grsecurity requires the use of a vanilla kernel from www.kernel.org. The kernel source supplied by your distribution's vendor has most likely been patched beyond recognition to grsecurity. With that caveat in mind, installation is simple.

FSF's High Priority Project List Now Has A Committee

The Free Software Foundation has now built up a committee to review their "High Priority Projects" list and they're looking for more feedback from the community. Nearly ten years ago is when the Free Software Foundation began listing what they viewed as the High Priority Free Software Projects in a list. This list has over time contained some definite high-priority projects related to freeing Java and Adobe PDF support and open graphics drivers to some more obscure projects of high priority like a free version of Oracle Forms, a replacement to OpenDWG libraries for CAD files, automatic transcription software, etc. I've personally called out many of the FSF HPP for what they're worth with my thoughts over the years.
