Physical security assessment: server room failures we found
Just completed physical security assessments for 8 client sites. Common failures:
- Server room doors with standard locks (no access control logging)
- No environmental monitoring — one client had a water leak for 3 days undetected
- Shared access codes — same PIN for all staff, never rotated
- No cameras covering server room entry
- Tailgating — we got into secured areas by following someone through badge-controlled doors 4 out of 8 times
Physical security is the most overlooked layer in cybersecurity. If I can touch your server, I own your network.
The tailgating stat is depressing but not surprising. We installed mantrap doors for our highest-security areas. Expensive but 100% effective.
For smaller clients who can't afford mantraps, we put a camera + door sensor combo that alerts when a single badge swipe results in two people entering (weight sensor on the floor mat).
Environmental monitoring is so cheap now. A $50 Raspberry Pi with temp/humidity/water sensors feeding into AlertMonitor. No excuse for not having it.
