AUTHORS

     This software was contributed to the FreeBSD Project by Network Associates Labs, the Security Research

     DARPA CHATS research program.

BUGS

     While the MAC Framework design is intended to support the containment of the root user, not all attack
     channels are currently protected by entry point checks.  As such, MAC Framework policies should not be
     relied on, in isolation, to protect against a malicious privileged user.
