NAME
mac_partition
- process partition policy
SYNOPSIS
To compile the process partition policy into your kernel,
place the following lines in your kernel
configuration file:
options MACoptions MAC_PARTITION
Alternately, to load the process partition module at boot time,
place the following line in your kernel configuration file:
options MAC
and in
loader.conf5:
mac_partition_load="YES"
DESCRIPTION
The
policy module implements a process partition policy,
which allows administrators to place running processes into
``partitions''
based on their numeric process partition
(specified in the process's MAC label).
Processes with a specified partition can only see processes that are in the
same partition.
If no partition is specified for a process, it can see all other processes
in the system
(subject to other MAC policy restrictions not defined in this man page).
No provisions for placing processes into multiple partitions are available.
Label Format
Partition labels take on the following format:
partition / value
Where
value
can be any integer value or
``none
''
For example:
The
policy module first appeared in
Fx 5.0
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.
