Mitigating Controls (NIST 800-53 r5) AI

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

Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.

Access enforcement that performs an atomic check-and-use decision directly stops the window in which a TOCTOU race can be exploited.

Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.

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

Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.

finds

Security testing in development can detect integer overflows before release.

prevents

Secure SDLC mandates input validation and arithmetic checks that prevent integer overflows.

degrades

Application security requirements include bounds checking and safe arithmetic to avoid overflow conditions.

degrades

Secure architecture principles require defensive coding patterns that mitigate integer wraparound risks.

prevents

Secure coding standards explicitly forbid unsafe integer operations and mandate overflow-safe constructs.

none

Reliable, synchronized time across systems narrows the exploitable window in which a resource state can change between a security check and its use.
