Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly requires checking that supplied parameters/fields have valid (non-missing) values before they are used.

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 require input validation and null/missing-value handling during coding and review.

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 missing-value flaws but does not itself prevent them.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate explicit handling of missing parameter values.

A.8.28 Secure coding partial match
prevents

Secure coding standards can require validation that every supplied parameter has a non-null value.
