introduction

Physical security includes all the real world things used for old heist movies. Men with masks and swag bags, safes, dynamite and the local sheriff are things in the physical security world.

what it is

Network security is the business of stopping bad guys fiddling around with a network. A physical attack, like applying a baseball bat to a computer, falls in the realm of physical security.

An attack is damage, intrusion or theft.

Three types of thing are used for defence.

  1. an obstacle, like an armoured door, that blocks an attack
  2. a detector, like a camera, that notices an attack
  3. a responder, like a security guard, who does something about an attack
