Contributors to the Security-Enhanced Linux

The National Security Agency (NSA)

Researchers in NSA's Information Assurance Research Office have implemented the Flask architecture in the major subsystems of the Linux kernel, including mandatory access controls on processes, files, and sockets. They also implemented the new operating system components provided by the Flask architecture, namely the security server and the access vector cache.

NAI Labs

Members of the Secure Execution Environments (SEE) group at NAI Labs have implemented several additional kernel mandatory access controls, such as the controls for procfs and devpts, and they are developing a general purpose security policy configuration. They have also contributed to some of the modified utilities.

Secure Computing Corporation (SCC)

Secure Computing Corporation developed a preliminary security policy configuration for the system that was used as a starting point for NAI Labs' configuration. They have also developed several new or modified utilities, and they are developing an application security policy.
