maclabel

MACLABEL(7)					       BSD Miscellaneous Information Manual					       MACLABEL(7)

NAME

     maclabel -- Mandatory Access Control label format

DESCRIPTION

     If Mandatory Access Control, or MAC, is enabled in the kernel, then in addition to the traditional credentials, each subject (typically a
     user or a socket) and object (file system object, socket, etc.) is given a MAC label.  The MAC label specifies the necessary subject-specific
     or object-specific information necessary for a MAC security policy to enforce access control on the subject/object.

     The format for a MAC label is defined as follows:

	   policy1/qualifier1,policy2/qualifier2,...

     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:

	   biba/low(low-low)
	   biba/high(low-high),mls/equal(equal-equal),partition/0

SEE ALSO

     mac(3), posix1e(3), mac_biba(4), mac_bsdextended(4), mac_ifoff(4), mac_mls(4), mac_none(4), mac_partition(4), mac_seeotheruids(4),
     mac_test(4), login.conf(5), getfmac(8), getpmac(8), ifconfig(8), setfmac(8), setpmac(8), mac(9)

HISTORY

     MAC first appeared in FreeBSD 5.0.
