introduction to physical security

The primary purpose of physical security is to prevent unauthorized access to equipment, installations, material, and documents; and to safeguard them against espionage, sabotage, damage, and theft.

Security-in-depth refers to the application of active and passive complementary security controls to protect national security and DOD assets, creating multiple layers of security.

The Antiterrorism Officer (ATO) is responsible for managing the installation or facility antiterrorism program.

The Physical Security Officer is charged with managing, implementing, and directing physical security programs, including the development and maintenance of physical security plans.

Restricted areas are designated for the security or safeguarding of property or material, and access is limited to authorized personnel to improve security by controlling access.

Vulnerabilities are weaknesses, characteristics, or circumstances that can be exploited by an adversary to gain access to or information from an asset.

The TWG is responsible for identifying foreign, domestic, and local threats and informing the installation commanding officer of current threat trends.

Warning signs are important as they can be easily read by persons approaching on foot or in a vehicle, clearly identifying restricted areas and enhancing security.

Protective measures such as covering windows with protective film can make them shatter-proof, reducing vulnerabilities in building security.

The purpose of conducting a risk analysis is to assess the impact of unwanted events and the likelihood of their occurrence to inform security measures.

Law enforcement officials are responsible for effective liaison with local, state, and federal law enforcement to coordinate support for antiterrorism concerns and emergency response.
