To compile the testing policy into your kernel, place the following lines
in your kernel configuration file:
Alternately, to load the testing module at boot time, place the following

and in loader.conf(5):
The mac_test policy module implements a testing facility for the MAC
framework. Among other things, mac_test will try to catch corrupt labels
the system is attempting to destroy and drop to the debugger. Addition-
ally, a set of statistics regarding the number of times various MAC
framework entry points have been called is stored in the

The mac_test policy module first appeared in FreeBSD 5.0 and was devel-
oped by the TrustedBSD Project.
This software was contributed to the FreeBSD Project by Network Asso-
ciates Labs, the Security Research Division of Network Associates Inc.
under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the
DARPA CHATS research program.
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.
