PR.PS-06 mostly match
prevents

Secure SDLC practices (reviews, static analysis, coding standards) directly prevent improper locking defects from being introduced.

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

Security testing can detect locking defects but does not itself implement locking controls.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle requires proper resource management patterns that prevent improper locking.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate exclusive-access controls and locking mechanisms.

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

Secure system architecture principles include concurrency and resource-locking design rules.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit missing or incorrect resource locks.

A.8.32 Change management partial match
prevents

Change management may catch locking issues introduced by modifications but does not prevent the weakness itself.
