|
2003-06-02 11:19:24 +00:00
|
|
|
If Mandatory Access Control, or MAC, is enabled in the kernel,
|
2002-10-28 22:54:54 +00:00
|
|
|
then in addition to the traditional credentials,
|
|
|
|
|
each subject
|
|
|
|
|
(typically a user or a socket)
|
|
|
|
|
and object
|
2003-06-02 11:19:24 +00:00
|
|
|
(file system object, socket, etc.\&)
|
2002-10-28 22:54:54 +00:00
|
|
|
is given a
|
2003-06-02 11:19:24 +00:00
|
|
|
.Em "MAC label" .
|
2002-10-28 22:54:54 +00:00
|
|
|
The MAC label specifies the necessary subject-specific or
|
|
|
|
|
object-specific information necessary for a MAC security policy
|
2003-06-02 11:19:24 +00:00
|
|
|
.\" .Pq Xr mac 9
|
2002-10-28 22:54:54 +00:00
|
|
|
to enforce access control on the subject/object.
|
|
|
|
|
.Pp
|
|
|
|
|
The format for a MAC label is defined as follows:
|
2003-06-02 11:19:24 +00:00
|
|
|
.Pp
|
|
|
|
|
.Sm off
|
|
|
|
|
.D1 Ar policy1 No / Ar qualifier1 , policy2 No / Ar qualifier2 , No ...
|
|
|
|
|
.Sm on
|
2002-10-28 22:54:54 +00:00
|
|
|
.Pp
|
|
|
|
|
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:
|
2003-06-02 11:19:24 +00:00
|
|
|
.Bd -literal -offset indent
|
|
|
|
|
