About this interactive

The first layer of physical security is the site itself and the ground around it. An unmarked building blends into its surroundings. Many data centers carry no name or logo, so passers-by cannot pick them out as a target; the security starts once you walk in. A one-way mirror lets people on one side watch without being seen from the other, like an interrogation room. It can guard an entry point or let staff observe without being identified. Fencing keeps people out of an area. Barbed wire on all or part of it makes it much harder to climb. A barricade also keeps people or vehicles out of an area, but it is usually portable and set up for a while, from a small temporary marker to a water-filled vehicle barrier. Bollards are sturdy posts that let foot traffic through and stop vehicles. They stay in the same spot and can often be lowered into the ground and raised again. To sort a card, ask what the need is: not being noticed, watching unseen, a permanent boundary, a temporary block, or stopping vehicles while people pass.
