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.
