It is based on the Linux Security Module architecture (which is not yet part of the 2.5 kernel). SELinux provides a whole set of mandatory access control features to protect parts of the system from each other. There is no "root" user in SELinux. Even if a server process is compromised, it is highly limited in the damage it can do to the rest of the system. According to the license page, SELinux is freely distributable under the terms of the GPL. It looks like a high-quality and useful contribution to the Linux community. There is a potential problem, however. Much of the actual work in the implementation of SELinux was done by Secure Computing Corporation (SCC). SCC, in its implementation of SELinux, used a technology that it calls type enforcement. As it turns out, SCC has a patent on this technology.
