MAC_NONE(4)              BSD Kernel Interfaces Manual              MAC_NONE(4)

NAME
     mac_none -- null MAC policy module

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

           options MAC
           options MAC_NONE

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

           options MAC

     and in loader.conf(5):

           mac_none_load="YES"

DESCRIPTION
     The mac_none policy module implements a sample MAC policy that has no
     effect on access control in the system.  Unlike 4(mac_stub), none of the
     MAC entry points are defined.

   Label Format
     No labels are defined for mac_none.

HISTORY
     The mac_none policy module first appeared in FreeBSD 5.0 and was devel-
     oped by the TrustedBSD Project.

AUTHORS
     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.

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.
