The general physical security golden rule....
โIf you didnโt authorize it, donโt let it in.โ
In more practical terms, this means:
Control access:
Only allow authorized personnel, devices, or materials into a protected area.
Verify identity:
Always check IDs, badges, or biometric credentials.
Monitor and enforce:
Use locks, cameras, guards, and alarms to ensure rules are followed.
Assume least privilege:
Give people only the access they need, no more.
Itโs the foundation for everything in physical securityโdoors, gates, surveillance, and even visitor policies.
