Mitigating Controls (NIST 800-53 r5) AI

prevent

Validates tensor size parameters before copy/loop operations to block malicious values that trigger the integer overflow.

prevent

Enforces memory bounds checking and protection that directly mitigates the out-of-bounds access resulting from the overflow.

detect

Detects unauthorized or corrupted code/data modifications that could exploit the integer-overflow flaw during tensor handling.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require use of safe arithmetic, bounds checks, and testing that prevent integer overflows.

detects

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.
