finds

Security testing in development can detect unreleased memory, providing partial coverage of the weakness.

prevents

Secure development life cycle mandates memory-management practices that reduce missing-release defects.

prevents

Application security requirements can specify explicit memory-release rules, partially mitigating the weakness.

prevents

Secure system architecture and engineering principles include resource-management guidelines that address memory leaks.

prevents

Secure coding standards directly require proper allocation/deallocation, covering most of this weakness.

finds

Capacity management may detect memory exhaustion symptoms but does not prevent the coding flaw.
