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 mostly match
degrades

Verification of identity assertions can detect incorrect tokens but does not prevent flawed generation logic.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly reduce the chance of implementing incorrect token generation.

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

Security testing in development can detect incorrect token generation before deployment.

A.8.24 Use of cryptography partial match
prevents

Proper use of cryptography ensures tokens are generated with correct algorithms, keys and entropy.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle practices include requirements and reviews that prevent flawed token-generation logic.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for correct token issuance and validation mechanisms.

A.8.28 Secure coding partial match
prevents

Secure coding standards reduce the likelihood of implementation errors that produce incorrect tokens.

A.8.5 Secure authentication partial match
prevents

Secure authentication mechanisms directly govern the correct generation and validation of security tokens.
