Overview[]
Physical security is important for protecting computer facilities and resources from espionage, sabotage, damage, and theft. Physical security is used to deter, delay, detect, and deny physical access by unauthorized individuals. Physical security restricts physical access to computer resources, usually by limiting access to the buildings and rooms in which the resources are housed and by periodically reviewing the access granted, in order to ensure that access continues to be appropriate. Examples of physical security include perimeter fencing, surveillance cameras, security guards, and locks.

Physical security involves the buildings that house computer centers, as well as the remote computer terminals. Within the established security perimeters, access to work areas must be restricted w1th physical barriers, appropriate placement of equipment and supplies, and universal wearing of identification badges. Emergencies must be prepared for, alternative power sources provided in many cases to assure uninterrupted process1ng, and incoming and outgoing materials inspected. Access to loading areas requires special precautions.[6]
