.Sh NAME
|
||||
.Nm mac_test
|
||||
.Nd MAC framework testing policy
|
||||
.Sh SYNOPSIS
|
||||
To compile the testing policy
|
||||
into your kernel, place the following lines in your kernel
|
||||
configuration file:
|
||||
.Cd "options MAC"
|
||||
.Cd "options MAC_TEST"
|
||||
.Pp
|
||||
Alternately, to load the testing module at boot time, place the following line
|
||||
in your kernel configuration file:
|
||||
.Cd "options MAC"
|
||||
.Pp
|
||||
and in
|
||||
.Xr loader.conf.5 :
|
||||
.Cd mac_test_load= Ns \&"YES"
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
policy module implements a testing facility for the MAC framework.
|
||||
Among other things,
|
||||
.Nm
|
||||
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
|
||||
.Va security.mac.test
|
||||
.Xr sysctl 8
|
||||
tree.
|
||||
.Ss Label Format
|
||||
No labels are defined for
|
||||

.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
policy module first appeared in
|
||||
.Fx 5.0
|
||||
and was developed by the TrustedBSD Project.
|
||||
.Sh AUTHORS
|
||||
This software was contributed to the
|
||||
.Fx
|
||||
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.
|
||||
.Sh BUGS
|
||||
See
|
||||
.Xr mac 9
|
||||
concerning appropriateness for production use.
|
||||
The TrustedBSD MAC Framework is considered experimental in
|
||||
.Fx .
|
||||
.Pp
|
||||
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.
