Three Most Common Physical Security Flaws (and How to Fix Them)

This report surveys common physical access-control weaknesses—misconfigured REX sensors that can be tricked (e.g., with compressed air), poorly installed or gapped doors susceptible to under‑door tools and handle manipulation, and low-frequency RFID badge systems that can be cloned—and provides practical mitigation guidance such as sensor repositioning, door hardware fixes, dynamic door bottoms, handle shrouds, monitoring/auditing of access, and employee training.
