PR.PS-06 mostly match
prevents

Secure SDLC practices directly enforce proper null handling via reviews and tooling rather than exception catching.

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

Security testing can detect improper exception handling but does not prevent the coding practice itself.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates defensive coding practices that can prevent NULL dereferences.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify input validation and pointer-safety rules.

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

Secure architecture principles encourage defensive design that avoids unsafe pointer use.

A.8.28 Secure coding partial match
prevents

Secure coding rules explicitly forbid catching NullPointerException to detect null dereferences.
