SELinux (Security Enhanced Linux)


http://en.wikipedia.org/wiki/Security-Enhanced_Linux

This is a Linux feature developed by NSA (National Security Agency).  It is not a Linux distribution, but a set of modification that can be applied to Unix-like OS (Operating System) kernels.


This is a really good overview article of what SELinux is and is not.  

MAC (Mandatory Access Controls) - enforced by SELinux.

DAC (Discretionary Access Control) - the old way of controlling what privileges a user can set on a file.

The SELinux policy has no concept of an all-powerful superuser.  It looks at things from the perspective of what is allowed.

An Internet-facing server should be locked down very strictly.

FC3 (Fedora Core 3) allows a targeted policy - "allow all, deny as needed."


Some more good information.  

AVC (access vector cache)
