Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation partial match

Input validation explicitly checks that supplied data matches expected types and rejects mismatches before they reach processing logic.

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 partial match
prevents

Secure SDLC practices directly require proper input validation and type checking to prevent this weakness.

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.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes input validation and type checking that directly mitigates improper handling of unexpected data types.

A.8.26 Application security requirements partial match
prevents

Application security requirements typically mandate strong input validation and type enforcement to prevent malformed data processing.

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

Secure system architecture principles encourage robust input handling but do not specifically address data-type validation.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly require type checking and input sanitization, directly addressing improper handling of unexpected data types.

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

Security testing can detect type-handling flaws but does not itself implement the preventive control.
