SC-49—Hardware-Enforced Separation And Policy Enforcement
>Control Description
Implement hardware-enforced separation and policy enforcement mechanisms between ⚙organization-defined security domains.
>Cross-Framework Mappings
NIST CSF 2.0
via NIST CSF 2.0 Concept Crosswalk>Supplemental Guidance
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.
