This software was contributed to the

part of the DARPA CHATS research program.
BUGS¶
See
mac(9) concerning appropriateness for
production use. The TrustedBSD MAC Framework is considered experimental in
FreeBSD.
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.
