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

Security testing in development can detect missing or incorrect null terminators before release.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and string handling rules that prevent missing null terminators.

A.8.26 Application security requirements partial match
prevents

Application security requirements can explicitly call for proper string termination and buffer handling.

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

Secure architecture principles include defensive coding practices that address buffer and string termination issues.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require correct null termination of strings and arrays.
