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 require code to validate paths and avoid unsafe link following.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

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

Security testing can detect link-following flaws before release.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC practices can mandate link-resolution checks and canonicalization before file access.

A.8.26 Application security requirements partial match
prevents

Application security requirements can explicitly require safe handling of symbolic links and path traversal.

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

Secure architecture principles include input validation and safe file-access design patterns.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address canonicalization and symlink attacks during implementation.

A.8.3 Information access restriction none match
mitigates

Access-control rules can limit which files are reachable, reducing exposure to malicious links.
