Mitigating Controls

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-03 partial match
blocks

Strong authentication mechanisms reduce reliance on unvalidated cookies for identity and access decisions.

PR.AA-04 partial match
blocks

Cookies commonly carry identity assertions; requiring their protection, conveyance, and verification directly eliminates the weakness.

PR.AA-05 partial match
blocks

Enforcing access policy and least privilege limits damage from cookie misuse but does not address cookie validation itself.

PR.DS-01 partial match
blocks

Integrity protections for data-at-rest can apply to cookie stores but do not cover validation during use.

PR.DS-02 partial match
blocks

Cryptographic integrity for data-in-transit directly mitigates tampering of cookies sent over the network.

A.5.27 Learning from information security incidents partial match
removes
A.8.26 Application security requirements partial match
blocks

Application security requirements can mandate cookie validation, integrity protection, and server-side session handling.

A.8.27 Secure system architecture and engineering principles partial match
removes
A.8.28 Secure coding partial match
prevents

Secure coding practices directly eliminate reliance on unvalidated cookies by requiring proper integrity checks and server-side verification.

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

Security testing can detect cookie-validation flaws but does not itself implement the required controls.

A.8.5 Secure authentication partial match
blocks

A.8.5 chooses, strengthens and protects the act of authenticating a claimed identity; CWE-565 is a flawed reliance on an unvalidated client-supplied token after identity has already been accepted, so the control never stops that acceptance from being exploited.
