Implement hardware-enforced separation and policy enforcement mechanisms between [Assignment: organization-defined security domains].

NIST discussion

System owners may require additional strength of mechanism and robustness to ensure domain separation and policy enforcement for specific types of threats and environments of operation. Hardware-enforced separation and policy enforcement provide greater strength of mechanism than software-enforced separation and policy enforcement.

Objectives and methods for SC-49

Determine if hardware-enforced separation and policy enforcement mechanisms are implemented between [Assignment: organization-defined security domains].

Examine: System and communications protection policy; procedures addressing cross-domain policy enforcement; system design documentation; system configuration settings and associated documentation; system audit records; system security plan; other relevant documents or records.

Interview: System/network administrators; organizational personnel with information security responsibilities; organizational personnel installing, configuring, and/or maintaining the system.

Test: Mechanisms supporting and/or implementing hardware-enforced security domain separation and policy enforcement.
