About this interactive
A switch can be locked down with strong passwords, yet anyone who can touch it can reboot it, bypass the password and see its whole configuration. That is why physical access has to be controlled too.
The lesson groups what we want to do physically into four goals.
Control access: decide who gets into the area, the building and the door. Fencing and bollards work on the area, vestibules and metal detectors on the building, and keys, fobs, badges and biometrics on the door.
Detect intruders: find out when someone has crossed a line they should not have, with guards, sensors, alarms and surveillance.
Secure equipment: protect the equipment itself, so it cannot walk off and people already in the room cannot get at it: equipment locks, smart lockers, safes, locking cabinets and racks.
Track assets: know what you own and where it is, with asset tags and inventory.
To sort a card, ask what the need is protecting: a way in, the knowledge that someone got in, the equipment itself, or the record of what you have.
