Mitigating Controls (NIST 800-53 r5) AI

AC-25 Reference Monitor good match

A reference monitor that is always invoked and analyzable structurally eliminates the non-atomic check-then-use pattern underlying TOCTOU.

AC-3 Access Enforcement good match

Proper enforcement of access authorizations on the resolved target resource stops a link from reaching an unintended object.

AC-6 Least Privilege partial match

Least-privilege limits the damage an attacker can cause after following an unintended link.

SC-39 Process Isolation partial match

Process isolation limits the blast radius of a successful TOCTOU exploitation but does not remove the race itself.

SI-10 Information Input Validation partial match

Validating file-name inputs can reject or canonicalize names that resolve to links before access occurs.
