SELinux is a new security concept for Linux based on security contexts applied to the processes and ressources of the system. The SELinux policy contains the rules which process may access which ressource. This policy is monitored by the kernel and ensures the integrity of the system. SELinux goes far beyond the traditional privilege system of a Linux system. SELinux even prevents an intruder taking over the system after compromising a process running with root privileges. RedHat, Fedora, Debian and Gentoo have included this concept in their distribution. This Course shows you how SELinux works and how to administer and customize the supplied policies.
Requirements: Very good knowledge of the system administration of a Linux operating system.
