Three rooms, three problems
A help desk has a cupboard of spare laptops. A cabinet of cables and switches sits in a corridor. A server room is in the basement.
Anyone could walk up to the cupboard. A cleaner could knock the cabinet. The basement could flood.
Physical controls solve all three. Each one stops harm before it starts.

Cycle 1: keep people out
A specialist lock is built to resist picking. A normal lock can be opened with thin tools. An anti-picking lock is much harder. A plain lock and key, or a code lock, is the basic version.
A barrier such as a fence stops people walking in. Bollards stop a car being driven at a building. A gate controls the one way in.
A cage goes round the equipment itself. A network cabinet with a locked door is a small cage.
Which control stops what
| Control | What it stops | Example |
|---|---|---|
| Anti-picking lock | Opening a door with tools | Door of the server room |
| Lock and key | Anyone opening a cupboard | Spare laptop cupboard |
| Fence | Walking onto the site | Round a data centre |
| Bollards | A vehicle hitting the building | In front of the loading bay |
| Gate | Cars and people entering freely | Car park entrance |
| Cage | Touching one rack or device | Locked rack in a shared room |
