Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

AC-3 directly requires correct enforcement of authorization decisions on every access request, structurally preventing incorrect checks.

AC-24 Access Control Decisions good match

AC-24 ensures access-control decisions are made and applied consistently, reducing the chance of an incorrect authorization result.

AC-25 Reference Monitor good match

A reference monitor that is always invoked and tamper-proof forces every authorization decision through a verified, correct path.

AC-6 Least Privilege good match

Least privilege restricts which users or processes may reach dangerous methods, limiting exposure.

CM-7 Least Functionality good match

Least functionality removes or disables non-essential dangerous methods from the exposed interface altogether.

PR.AA-05 full match
prevents

Enforcing least-privilege authorization directly prevents unrestricted dangerous API methods.

PR.PS-06 mostly match
prevents

Secure SDLC practices stop developers from exposing dangerous functions in the first place.

ID.RA-01 partial match
prevents

Vulnerability identification processes will surface exposed dangerous methods during assessment.

PR.IR-01 partial match
prevents

Logical access controls at the network/environment layer can limit reachability of exposed functions.

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

Security testing can detect exposed dangerous functions, but does not prevent their initial introduction.

A.5.15 Access control partial match
prevents

Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.

A.5.18 Access rights partial match
prevents

Enforcing policy-driven approval and role-change reviews stops incorrect or stale authorization decisions from remaining in effect after job changes or terminations.

A.8.18 Use of privileged utility programs partial match
degrades

Restricting privileged utility programs reduces exposure of dangerous functions, but does not eliminate the underlying weakness.

A.8.2 Privileged access rights partial match
prevents

Privileged access rights limit who can invoke dangerous methods, but do not address whether the method itself should exist.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle requires removal or protection of dangerous APIs during design and coding.
