Secure SDLC practices directly require proper input validation and range checks that prevent missing minimum bounds.

A.6.6 Confidentiality or non-disclosure agreements partial match
removes
A.8.25 Secure development life cycle partial match
blocks

Secure development life cycle mandates input validation and boundary checks that would catch missing minimum-range verification.

A.8.26 Application security requirements partial match
blocks

A.8.26 only requires that security requirements (including resilience against injections or input validation) be identified and specified during development or acquisition; it does not itself enforce, implement or assure any check that stops a missing lower-bound comparison from being exploitable.

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

A.8.27 mandates establishing and applying secure engineering principles (including least privilege, security by design, and design reviews) but does not itself implement range checks or stop a missing-minimum numeric comparison from being coded and exploited

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid numeric comparisons that omit the lower bound, directly mitigating CWE-839.

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

Security testing in development and acceptance can detect missing minimum checks through boundary-value and fuzz testing.
