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

Security testing can detect incomplete neutralization but does not prevent the weakness itself.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and neutralization of all equivalent special elements.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules for handling special characters and equivalent encodings.

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

Secure system architecture principles require consistent canonicalization and neutralization of equivalent inputs.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address proper neutralization of all equivalent special elements.
