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

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.
