Short for Security-enhanced Linux, SELinux is a
Linux variation that can be fully integrated into the
Linux 2.6 kernel series and also several Linux distributions. SELinux has no
concept of a root user, instead it
includes enhanced security functionality through enforced
mandatory access controls (MAC).
SELinux was created by the National Security Agency as an example of how
mandatory access controls, which can confine the actions of any process, can be
added into Linux. It was released to the
open_source.html development community in 2000.
