Mitigating Controls (NIST CSF 2.0) AI

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-01 partial match
blocks

Hardened baselines and config management directly suppress verbose server error output.

PR.PS-06 partial match
blocks

Secure SDLC explicitly requires sanitized error handling and information disclosure controls.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

A.8.15 Logging partial match
degrades

Logging policy can require suppression of sensitive data in error responses.

A.8.25 Secure development life cycle partial match
blocks

Secure SDLC mandates handling of error messages to avoid information disclosure.

A.8.26 Application security requirements partial match
blocks

A.8.26 only requires that error message handling be identified as a possible security requirement during requirements gathering; it does not mandate, enforce or implement any restriction on sensitive information in those messages, so the weakness can still be present and exploitable.

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

A.8.27 mandates establishing and applying secure engineering principles (defense-in-depth, least privilege, security by design, hardening, zero-trust) and performing security-oriented design reviews; it does not stop server error messages from containing sensitive information when the error condition occurs.

A.8.28 Secure coding partial match
prevents

Secure coding standards prohibit embedding sensitive data in server error messages.

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

Security testing can detect and require remediation of verbose error messages.
