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 require proper error handling to avoid leaking exception details in shell messages.

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.8.28 Secure coding mostly match
prevents

Secure coding standards directly require handling exceptions without exposing internal details.

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

Security testing can detect exposed error messages but does not prevent them by itself.

A.8.15 Logging partial match
mitigates

Logging can capture error messages but does not prevent their exposure to users.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC practices include proper exception handling to avoid leaking sensitive data in error messages.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate safe error handling but do not directly address this weakness.

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

Secure architecture principles encourage generic error responses but are not specific to shell error messages.
