Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent developers from embedding sensitive information inside debugging statements or code paths.

PR.DS-10 partial match
prevents

Explicitly calls for removing confidential data from processes, logs, and memory dumps that debug code commonly exposes.

PR.PS-01 partial match
prevents

Hardened configuration baselines and deployment checks can ensure debug features and associated data are disabled in production.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

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

Security testing in development catches debug statements and sensitive data leaks.

A.8.31 Separation of development, test and production environments mostly match
prevents

Separation of environments reduces accidental exposure of debug builds to production.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates removal of debug code and sensitive data before release.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly prohibit embedding secrets or debug statements.

A.8.15 Logging none match
none

Logging controls may capture debug output, but do not prevent its creation.

A.8.33 Test information none match
none

Test data handling rules discourage use of real sensitive data in debug contexts.
