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

Security testing in development can detect missing XML validation but does not itself implement the control.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and schema enforcement for untrusted XML.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for validation of external data formats including XML.

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

Secure architecture principles encourage defensive input handling but do not prescribe XML schema validation.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require validation of untrusted XML against a proper schema.
