Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and analysis (static, dynamic, fuzzing) finds integer-overflow-to-allocation defects before deployment.

Mandates documented development standards and tools that enforce secure coding rules against unsafe integer arithmetic.

Requires engineering principles such as safe arithmetic and bounds-checked allocation that directly stop integer overflow during memory-size computation.

Validates untrusted size/offset inputs before they reach allocation calculations, structurally blocking the integer overflow path.

prevents

Secure SDLC practices directly prevent integer-overflow flaws during development, but eliminating only this CWE covers only part of the broad control intent.

finds

Security testing can detect integer-overflow-to-buffer-overflow conditions during development.

prevents

Secure development life cycle mandates practices that can catch integer overflows before deployment.

prevents

Application security requirements can specify safe integer handling and bounds checking.

prevents

Secure architecture principles encourage use of safe arithmetic libraries and overflow detection.

prevents

Secure coding standards directly require prevention of integer overflows that lead to buffer overflows.
