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-06 mostly match
prevents

Secure SDLC practices directly prevent unsafe assertions from being coded in reachable paths.

DE.CM-09 partial match
prevents

Runtime monitoring of software can detect assertion-triggered crashes as adverse events.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover and record reachable-assertion flaws before deployment.

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

Security testing in development can detect reachable assertions before release, reducing the likelihood of exploitation.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates defensive coding and input validation that prevent reachable assertions from being triggered by untrusted data.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify that assertions must not be reachable from attacker-controlled inputs.

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

Secure architecture principles discourage the use of assertions for runtime error handling that an attacker could exploit.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly ban the use of assert() or equivalent statements that can be triggered by external input.
