Implementation Guidance

Determine if: - [AC-03(03)_ODP[01]; mandatory access control policy enforced over the set of covered subjects is defined] is uniformly enforced across the covered subjects within the system. - [AC-03(03)_ODP[02]; mandatory access control policy enforced over the set of covered objects is defined] is uniformly enforced across the covered objects within the system.

Validation Procedures

Examine: [SELECT FROM: Access control policy; mandatory access control policies; procedures addressing access enforcement; system design documentation; system configuration settings and associated documentation; list of subjects and objects (i.e., users and resources) requiring enforcement of mandatory access control policies; system audit records; system security plan; other relevant documents or records]. Interview: [SELECT FROM: Organizational personnel with access enforcement responsibilities; system/network administrators; organizational personnel with information security responsibilities; system developers]. Test: [SELECT FROM: Automated mechanisms implementing mandatory access control].
