Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly enforces correct handling of parameter counts and defined values before processing occurs.

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
blocks

Secure SDLC practices directly require proper input validation and parameter handling to prevent this weakness.

A.6.6 Confidentiality or non-disclosure agreements partial match
removes
A.8.19 Installation of software on operational systems partial match
removes
A.8.25 Secure development life cycle partial match
blocks

Secure development lifecycle includes input validation and parameter handling requirements that reduce missing-value errors.

A.8.26 Application security requirements partial match
blocks

A.8.26 requires identifying and specifying requirements (incl. input validation, resilience against SQLi/buffer overflows, integrity checks) that can address improper value handling during development, but this is only a minority slice of CWE-229's broad class of value-count/undefined cases across all input and parameter sites.

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

A.8.27 mandates security-by-design principles (e.g. distrust input, least privilege, fail securely, data validation/sanitization) and design reviews that can stop improper value handling from reaching production in many cases, but leaves a bounded remainder (e.g. legacy code, outsourced development where principles are only contractually required, or incomplete application of the full set of principles).

A.8.28 Secure coding partial match
prevents

Secure coding standards mandate proper handling of missing or undefined parameters, directly addressing this weakness.
