SELinux

Security-Enhanced Linux

是一種實現強制訪問控制的系統）的項目最初是由美國安全局(NSA)發起。

Secure Computing Corporation (SCC)和MITRE直接參與了開發，許多實驗室也加入其中。

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.

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.
