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.AA-04 none match
prevents

PR.AA-04 addresses protection/verification of identity assertions in SSO/federation contexts while CWE-757 concerns protocol-level crypto algorithm negotiation, so the control neither prevents nor meaningfully mitigates the weakness.

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

Security testing can detect and block algorithm downgrade vulnerabilities before deployment.

A.8.21 Security of network services partial match
mitigates

Ensures network services use secure cryptographic parameters, reducing downgrade risk.

A.8.24 Use of cryptography partial match
prevents

Mandates use of strong, approved cryptographic algorithms, directly preventing downgrade to weaker ones.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC practices include selecting strong crypto algorithms during design and implementation.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify minimum cryptographic strength to avoid downgrades.

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

Secure architecture principles include enforcing strong algorithm selection in protocol design.
