Determine if:
- AC-03(03)[01] [Assignment: mandatory access control policy] is enforced over the set of covered subjects specified in the policy;
- AC-03(03)[02] [Assignment: mandatory access control policy] is enforced over the set of covered objects specified in the policy;
- AC-03(03)(a)
- AC-03(03)(a)[01] [Assignment: mandatory access control policy] is uniformly enforced across the covered subjects within the system;
- AC-03(03)(a)[02] [Assignment: mandatory access control policy] is uniformly enforced across the covered objects within the system;
- AC-03(03)(b)
- AC-03(03)(b)(01) [Assignment: mandatory access control policy] and [Assignment: mandatory access control policy] specifying that a subject that has been granted access to information is constrained from passing the information to unauthorized subjects or objects are enforced;
- AC-03(03)(b)(02) [Assignment: mandatory access control policy] and [Assignment: mandatory access control policy] specifying that a subject that has been granted access to information is constrained from granting its privileges to other subjects are enforced;
- AC-03(03)(b)(03) [Assignment: mandatory access control policy] and [Assignment: mandatory access control policy] specifying that a subject that has been granted access to information is constrained from changing one of more security attributes (specified by the policy) on subjects, objects, the system, or system components are enforced;
- AC-03(03)(b)(04) [Assignment: mandatory access control policy] and [Assignment: mandatory access control policy] specifying that a subject that has been granted access to information is constrained from choosing the security attributes and attribute values (specified by the policy) to be associated with newly created or modified objects are enforced;
- AC-03(03)(b)(05) [Assignment: mandatory access control policy] and [Assignment: mandatory access control policy] specifying that a subject that has been granted access to information is constrained from changing the rules governing access control are enforced;
- AC-03(03)(c) [Assignment: mandatory access control policy] and [Assignment: mandatory access control policy] specifying that [Assignment: subjects] may explicitly be granted [Assignment: privileges] such that they are not limited by any defined subset (or all) of the above constraints are enforced.
