Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

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

SA-15 Development Process, Standards, and Tools partial match

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

SA-8 Security and Privacy Engineering Principles partial match

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

SI-10 Information Input Validation partial match

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

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

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

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

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

A.8.25 Secure development life cycle partial match
prevents

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

A.8.26 Application security requirements partial match
prevents

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

A.8.27 Secure system architecture and engineering principles partial match
prevents

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

A.8.28 Secure coding partial match
prevents

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