Mitigating Controls
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.6.3 is awareness/education/training that informs people of their responsibilities and improves skills; it does not stop a UI misrepresentation weakness from remaining present or from being exploitable (e.g. in phishing).
Web filtering can block known phishing sites that exploit UI misrepresentation.
Secure development lifecycle includes UI/UX security requirements that can prevent misrepresentation of critical information.
A.8.26 only requires that security requirements (including some that could indirectly relate to UI trustworthiness) be identified and specified during development; it does not itself enforce, implement, or stop UI misrepresentation from being exploitable.
Secure coding practices can prevent UI flaws that obscure or spoof critical information.
Security testing can detect UI misrepresentation vulnerabilities before deployment.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-451, a class-level weakness, and none of its children carries one either.
