Security subsystems application/evaluation guide in General Services Administration

The US General Services Administration (GSA) provides physical security systems at GSA facilities to protect against burglary, theft, sabotage, espionage and attack. The security systems program entails systems analysis, design, installation and maintenance in GSA´s facilities by engineers and technicians. GSA´s physical security philosophy is to increase the time required to gain unauthorized access by providing one or more layers of protection. The authors describe the methodology used in developing application, selection, and evaluation criteria for security subsystems. The criteria are in a tabular format to assist security system program personnel in providing balanced and cost-effective systems that are acceptable to the facility and accommodates operational needs. The `Security Systems Design Guide´, developed by GSA to assist security engineers in design and construction programming, is described
