mac_stub(4)

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 MAC
      options 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.conf(5):
      mac_stub_load="YES"

DESCRIPTION

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.

Label Format

No labels are defined for mac_stub.

HISTORY

The mac_stub policy module first appeared in FreeBSD 5.1 and

was developed by the TrustedBSD Project.

AUTHORS

This software was contributed to the FreeBSD Project by Net

work Associates Labs, the Security Research Division of Network Associ

ates Inc.

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 pro

tected by entry
point checks. As such, MAC Framework policies should not be

relied on,
in isolation, to protect against a malicious privileged us

er.
