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 correct output encoding to match downstream context, but eliminating only this flaw covers a narrow slice of the broader control.

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
degrades

Secure coding directly addresses proper output encoding for context, covering most of the weakness and the control's intent.

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

Security testing can detect encoding mismatches, but testing alone does not prevent the weakness at source.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle requires encoding-aware output handling, but does not mandate context-specific encoding checks.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify correct output encoding, yet the control is broader than this single weakness.
