Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Access enforcement directly stops resources from being reachable by actors outside the intended control sphere.

SC-3 Security Function Isolation good match

Security function isolation is the canonical mechanism for protecting higher-privilege compartments.

SC-39 Process Isolation good match

Process isolation maintains separate execution domains so one process cannot affect another’s privilege level.

AC-4 Information Flow Enforcement good match

Information flow enforcement structurally prevents unintended cross-sphere data or resource exposure.

AC-6 Least Privilege good match

Least privilege reduces the set of actors that can reach a resource, limiting wrong-sphere exposure.

SC-2 Separation of System and User Functionality good match

Explicit separation of user and management functionality implements the required compartmentalization.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-05 full match
prevents

Least-privilege policy directly enforces separation of privilege levels and access rights.

PR.IR-01 mostly match
prevents

Network and environment segmentation implements the isolation required to prevent unauthorized cross-compartment access.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.5.3 Segregation of duties mostly match
degrades

Segregation of duties directly enforces separation of privilege levels and functions.

A.8.22 Segregation of networks mostly match
prevents

Network segregation is a classic technical control for isolating different privilege domains.

A.8.27 Secure system architecture and engineering principles mostly match
prevents

Secure system architecture principles explicitly call for isolation and least-privilege boundaries.

A.8.31 Separation of development, test and production environments mostly match
prevents

Separation of development, test and production environments is a direct application of compartmentalization.

A.5.15 Access control partial match
degrades

Access control policies establish the boundaries that isolation must enforce.

A.5.18 Access rights partial match
degrades

Managing access rights is the operational mechanism for compartmentalizing privileges.
