AUTHORS

This software was contributed to the FreeBSD Project by Net

work Associates Labs, the Security Research Division of Network Associ

ates Inc.

part of the

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 pro

tected by entry
point checks. As such, MAC Framework policies should not be

relied on,
in isolation, to protect against a malicious privileged us

er.
