finds

Security testing in development can detect deadlock conditions through stress and concurrency testing.

prevents

Secure development lifecycle requires deadlock analysis and avoidance techniques during design and coding.

prevents

Application security requirements can mandate proper lock acquisition/release patterns.

prevents

Secure system architecture principles include concurrency controls and resource-locking discipline that prevent deadlock.

prevents

Secure coding standards mandate safe lock ordering, timeouts, and deadlock detection patterns.

prevents

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