Security is a power-up in Call of Duty: Advanced Warfare in Exo Zombies. It turns on all the security traps in the map for 30 seconds. It will also make any opened door within the map deadly as when a Zombie tries to get through it, it'll close itself, crushing the zombie instantly, then opening itself back up when another tries to pass it. The opened doors will have a cooldown time that lasts about a few seconds upon crushing a zombie.
