Other Security System Elements

Security system design focuses on devices to identify and screen individuals at entry points — “access control”— which is all you would need if there were 100% reliability of identification, total trustworthiness of the intentions of people admitted, and the physical perfection of unbreakable walls, doors, windows, locks, and ceilings. To cover for inevitable failings due to flaws or sabotage, security systems ordinarily incorporate additional methods of protection, monitoring, and recovery.

Building Design

When building a new facility or renovating an old one, physical security can be addressed from the ground up by incorporating architectural and construction features that discourage or thwart intrusion. Security considerations in the structure and layout of a building generally relate to potential entry and escape routes, access to critical infrastructure elements such as HVAC and wiring, and potential sources of concealment for intruders.
