Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Access enforcement directly stops unauthorized callers from invoking dangerous API methods or functions.

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.

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

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.

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.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.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.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate that dangerous methods are not exposed in interfaces.

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

Secure architecture principles discourage exposing dangerous functions, but do not guarantee their absence.
