Episode 159: Physical Security Fundamentals — Access Control and Asset Disposal

While cyber defenses are critical, physical security is just as important. In this episode, we explain how physical access controls protect infrastructure from unauthorized tampering, theft, or sabotage. You’ll learn about badge systems, biometrics, mantraps, camera placement, and hardware locks. These controls help restrict access to wiring closets, server rooms, and device enclosures.

We also cover secure asset disposal practices such as drive wiping, degaussing, shredding, and certificate documentation. Disposing of equipment improperly can lead to data leakage and compliance violations. This episode reinforces the idea that network security must include the physical realm—from building entry to hardware end-of-life procedures.
