Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly rejects or sanitizes untrusted path strings before they reach filesystem operations.

AC-3 Access Enforcement partial match

Enforces authorization checks on the actual resource accessed, blocking unauthorized files even when a malicious path is supplied.

AC-6 Least Privilege partial match

Least-privilege limits the set of files or directories any subject can affect, shrinking the blast radius of a path-control flaw.

PR.AA-05 partial match

blocks

Least-privilege file authorization directly limits damage from externally controlled paths.

PR.PS-06 partial match
