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.
Secure SDLC practices directly require input validation and null/missing-value handling during coding and review.

Security testing can detect missing-value flaws but does not itself prevent them.
Application security requirements can mandate explicit handling of missing parameter values.
Secure coding standards can require validation that every supplied parameter has a non-null value.
