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 proper input validation and range checks that prevent missing minimum bounds.

Security testing in development and acceptance can detect missing minimum checks through boundary-value and fuzz testing.
Secure development life cycle mandates input validation and boundary checks that would catch missing minimum-range verification.
Application security requirements include explicit validation rules for numeric ranges, directly addressing the missing minimum check.
Secure system architecture principles require defensive input handling and range validation to prevent out-of-bounds values.
Secure coding standards explicitly forbid numeric comparisons that omit the lower bound, directly mitigating CWE-839.
