NAME
mac_stub
- MAC policy stub module
SYNOPSIS
To compile the sample policy
into your kernel, place the following lines in your kernel
configuration file:
options MACoptions MAC_STUB
Alternately, to load the sample module at boot time, place the following line
in your kernel configuration file:
options MAC
and in
loader.conf5:
mac_stub_load="YES"
DESCRIPTION
The
policy module implements a sample MAC policy that has no effect on
access control in the system.
Unlike
mac_none4,
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.
The
policy module first appeared in
Fx 5.1
and was developed by the
TrustedBSD
Project.

BUGS
See
mac(9)
concerning appropriateness for production use.
The
TrustedBSD
MAC Framework is considered experimental in
Fx .
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.
