Mitigating Controls (NIST 800-53 r5) AI

AC-25 Reference Monitor good match

Requires a tamperproof, always-invoked reference monitor that structurally blocks bypass via any alternate path.

AC-3 Access Enforcement good match

Enforces authorization checks on every logical access path, eliminating unauthenticated alternate channels.

AC-6 Least Privilege good match

AC-6 limits granted privileges, reducing the chance that files or directories become reachable by external parties.

IA-2 Identification and Authentication (Organizational Users) good match

Mandates unique identification and authentication for all organizational users, covering the primary authentication requirement.

AC-4 Information Flow Enforcement partial match

AC-4 enforces information flow rules that can block unauthorized external access to files or directories.

SC-7 Boundary Protection partial match

Controls all external and key internal interfaces, reducing the chance of unauthenticated alternate channels.

PR.AA-03 full match
prevents

Requiring authentication on every channel and path directly eliminates alternate-path bypasses.

PR.AA-05 mostly match
prevents

Enforcing authorizations and least privilege across all access vectors prevents unauthenticated alternate paths.

PR.IR-01 mostly match
prevents

Protecting networks and environments from unauthorized logical access blocks bypass via undocumented channels.

PR.DS-01 partial match
prevents

Data-at-rest protections such as encryption or ACLs reduce the impact of unintended file exposure.

PR.PS-01 partial match
prevents

Hardened configuration baselines commonly include file-system permission settings that limit external access.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect alternate-path bypasses but does not prevent them in production.

A.8.5 Secure authentication mostly match
degrades

Secure authentication control directly mitigates bypass by requiring strong, consistent authentication on all paths.

A.5.11 Return of assets partial match
mitigates

By tracing and retrieving all copies of information stored on endpoint and portable devices, the control reduces the likelihood that files remain accessible outside the organization’s security perimeter.

A.5.12 Classification of information partial match
mitigates

Labeling information according to its sensitivity and specifying corresponding protection measures makes it less probable that files or directories containing sensitive content will be left accessible to external parties.

A.5.15 Access control partial match
prevents

Access control policy directly addresses alternate authentication paths by requiring all channels to enforce authentication.

A.5.17 Authentication information partial match
degrades

Authentication information management ensures credentials and mechanisms are consistently applied across all access paths.
