Mitigating Controls (NIST 800-53 r5) AI

CM-6 Configuration Settings good match

Establishing secure configuration settings for web components includes requiring appropriate SameSite attributes on sensitive cookies.

SC-23 Session Authenticity good match

Proper SameSite settings on session cookies directly help protect the authenticity of communications sessions against cross-site misuse.

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 mostly match
prevents

Secure configuration baselines and enforcement directly require proper SameSite settings on sensitive cookies.

PR.PS-06 mostly match
prevents

Secure SDLC practices include coding standards and reviews that mandate correct SameSite attributes.

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.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect missing SameSite attributes but does not prevent the weakness.

A.8.26 Application security requirements partial match
prevents
