The MAC label specifies the necessary subject-specific or object-specific information necessary for a MAC security policy .Pq Xr mac 9
to enforce access control on the subject/object.

p The format for a MAC label is defined as follows:

p .Sm off .D1 Ar policy1 No / Ar qualifier1 , policy2 No / Ar qualifier2 , No ... .Sm on

p A MAC label consists of a policy name, followed by a forward slash, followed by the subject or object's qualifier, optionally followed by a comma and one or more additional policy labels. For example: d -literal -offset indent biba/low(low-low) biba/high(low-high),mls/equal(equal-equal),partition/0 .Ed .Sh SEE ALSO .Xr mac 3 , .Xr posix1e 3 , .Xr mac_biba 4 , .Xr mac_bsdextended 4 , .Xr mac_ifoff 4 , .Xr mac_mls 4 , .Xr mac_none 4 , .Xr mac_partition 4 , .Xr mac_seeotheruids 4 , .Xr mac_test 4 , .Xr login.conf 5 , .Xr getfmac 8 , .Xr getpmac 8 , .Xr ifconfig 8 , .Xr setfmac 8 , .Xr setpmac 8 , .Xr mac 9 .Sh HISTORY MAC first appeared in .Fx 5.0 . .Sh AUTHORS This software was contributed to the .Fx Project by NAI Labs, the Security Research Division of Network Associates Inc. under DARPA/SPAWAR contract N66001-01-C-8035
