V16.5.1

Mitigating Controls (NIST 800-53 r5) AI

SI-11 Error Handling good match

prevent

Directly requires error messages to avoid inclusion of sensitive information, addressing the CWE-209 root cause of the disclosure.

SI-15 Information Output Filtering partial match

prevent

Filters outbound information to suppress sensitive data that could otherwise leak through error paths.

SI-10 Information Input Validation minimal match

prevent

Input validation reduces the conditions that trigger verbose error generation containing sensitive details.

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-06 mostly match

prevents

Secure SDLC practices directly require sanitized error handling to prevent sensitive data disclosure.

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

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 explicitly forbid exposing sensitive data in errors.

A.8.29 Security testing in development and acceptance mostly match

detects

Security testing can detect error messages that leak sensitive information.

A.8.15 Logging partial match

degrades

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

A.8.25 Secure development life cycle partial match

prevents

Secure SDLC mandates error-handling rules that avoid leaking sensitive information.
