# SC-49 Hardware-enforced Separation and Policy Enforcement

NIST SP 800-53 control. Family: SC System and Communications Protection. Function: preventative. In no baseline. Mapping licence: CC BY-SA 4.0.

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

## Clauses by framework (3 frameworks)
- nist_csf_2: PR.PS-03
- rbi_csf: Annex1.4
- hkma_tme1: TME1.7.3
OSA's mapping for nist_csf_2 takes NIST's published crosswalk as its base. A clause not marked as OSA's own is in that crosswalk.
