Physical Security and Deception Technologies

An attacker with physical access to a network device can often bypass logical access controls entirely. It does not matter if a network is fortified by next-generation firewalls, rigorous intrusion prevention systems, and mathematically unbreakable encryption if an adversary can simply walk into the server room, unplug a core router, or extract a hard drive. Physical security controls represent the outermost layer of a defense-in-depth strategy, an architectural paradigm that relies on multiple overlapping security controls to protect network assets. In this design, physical security barriers are not merely static obstacles; they intentionally slow down attackers to give security personnel time to respond.
