NAME
     mac_test — MAC framework testing policy


SYNOPSIS
     To compile the testing policy into your kernel, place the following lines in your kernel configuration
     file:

           options MAC
           options MAC_TEST

     Alternately, to load the testing module at boot time, place the following line in your kernel configuration
     file:

           options MAC

     and in loader.conf(5):

           mac_test_load="YES"


DESCRIPTION
     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.
     Additionally, a set of statistics regarding the number of times various MAC framework entry points have
     been called is stored in the security.mac.test sysctl(8) tree.

   Label Format
     No labels are defined for mac_test.

HISTORY
     The mac_test policy module first appeared in FreeBSD 5.0 and was developed by the TrustedBSD Project.


AUTHORS
     This software was contributed to the FreeBSD Project by Network Associates 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.


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.
