Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

SI-10 requires validity checks on supplied inputs, directly stopping acceptance of internally inconsistent complex data.

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 consistency validation for complex inputs.

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

Security testing can detect consistency flaws but does not prevent them at design time.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle requires input validation and consistency checks that directly address CWE-1288.

A.8.26 Application security requirements partial match
prevents

Application security requirements include validation of complex inputs and cross-field consistency.

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

Secure architecture principles encourage robust input handling but do not specifically mandate consistency validation.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly require validation of interrelated input fields to prevent CWE-1288.
