MAC_STUB(4) BSD Kernel Interfaces Manual MAC_STUB(4)
mac_stub -- MAC policy stub module
To compile the sample policy into your kernel, place the following lines
in your kernel configuration file:
Alternately, to load the sample module at boot time, place the following
line in your kernel configuration file:
and in loader.conf(5):
The mac_stub policy module implements a sample MAC policy that has no
effect on access control in the system. Unlike mac_none(4), each MAC
entry point is defined as a ``no-op'', so the policy module will be
entered for each event, but no change in system behavior should result.
No labels are defined for mac_stub.
mac(4), mac_biba(4), mac_bsdextended(4), mac_ifoff(4), mac_lomac(4),
mac_mls(4), mac_none(4), mac_partition(4), mac_portacl(4),
mac_seeotheruids(4), mac_test(4), mac(9)
The mac_stub policy module first appeared in FreeBSD 5.1 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.
