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

Security testing can detect excessive iteration through stress and fuzz testing.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle requires input validation and loop bounds, directly limiting excessive iteration.

A.8.26 Application security requirements partial match
prevents

Application security requirements include resource-consumption limits that prevent unbounded loops.

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

Secure architecture principles mandate defensive coding patterns such as loop termination checks.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly forbid unbounded loops and require explicit iteration limits.
