Master's Student: A Quick and Dirty Guide To Kernel Hardening with GrSecurity

LinuxSecurity.com: Our resident Master's student Gian Spicuzza chimes in this month with a great feature HowTo on Kernel Hardening! There are a number of ways to lock down a system, and RBAC (role based access control) is one of them. Read on to learn more about what makes RBAC so useful, and to read one of the best overviews on Low/Medium/High Security...

The combination of the Linux kernel and GNU packages has always been regarded as a secure operating system, but can it be more secure? Kernel hardening is the answer to tightening up the Linux backbone. GrSecurity, a kernel patch for Linux, is one of the more popular approaches...
