SC-46 Cross Domain Policy Enforcement

NIST SP 800-53 (controls) 5.2.0 against 5.2.0

unchanged SC

Title

Cross Domain Policy Enforcement

Control

Implement a policy enforcement mechanism [Selection: physically; logically] between the physical and/or network interfaces for the connecting security domains.

Discussion

For logical policy enforcement mechanisms, organizations avoid creating a logical path between interfaces to prevent the ability to bypass the policy enforcement mechanism. For physical policy enforcement mechanisms, the robustness of physical isolation afforded by the physical implementation of policy enforcement to preclude the presence of logical covert channels penetrating the security domain may be needed.
