blocks

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

blocks

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

blocks

A.8.27 mandates security-by-design, defence-in-depth, least-privilege, distrust-external-input and hardening principles plus design reviews that can catch and block insecure junction/mount-point handling in the architecture and code, but leaves a bounded remainder (e.g. third-party libraries, runtime config, or post-deployment changes) where the flaw can still be introduced and exploited.

prevents

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