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 improper junction/mount-point handling during design and coding.

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 junction/mount-point weaknesses before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle can mandate junction/mount-point validation during design and coding.

A.8.26 Application security requirements partial match
prevents

Application security requirements can explicitly require protection against Windows reparse-point attacks.

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

Secure system architecture principles include canonicalization and path-traversal defenses that mitigate junction attacks.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly address safe file/directory handling to prevent insecure junction operations.

A.8.3 Information access restriction none match
mitigates

Information access restriction reduces exposure but does not prevent the technical flaw itself.
