PR.AA-04 partial match
blocks

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

PR.PS-06 partial match
blocks

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

A.8.24 Use of cryptography partial match
blocks

A.8.24 governs the selection, strength, key management and deployment of cryptography to protect information per policy; it has no bearing on whether a security token generation mechanism produces correct (or incorrect) tokens that differentiate permitted actions.

A.8.25 Secure development life cycle partial match
blocks

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

A.8.26 Application security requirements partial match
blocks

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

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

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

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

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