Physical Security

Physical Security (PS) Subgroup


Identify and prioritize interagency physical security requirements to protect forces, vital equipment, and facilities against terrorist attacks, execute research and development projects that address those requirements, and transition successful prototypes into programs of record or into immediate field use to meet urgent operational needs.

The Physical Security (PS) Subgroup identifies the physical security requirements of federal, state, and local agencies, both within the United States and abroad, and develops technologies to protect their personnel and property from terrorist attacks. The subgroup manages projects to develop prototype hardware, software, and systems for technical and operational evaluation by user agencies.

Focus Areas

Blast Effects and Mitigation

Blast Effects and MitigationTest and evaluate infrastructure components and systems to investigate and characterize potential damage to identify mitigation strategies to protect against current and evolving threats. Components include but are not limited to: buildings, bridges, tunnels, and structural members. Develop test protocols to ensure repeatable and consistent results where components and threats require evaluation under unique circumstances. Emphasize blast, debris, and shrapnel effects. Testing may also include gunfire, mortars, and rockets. Mitigation strategies may include hardened infrastructure, improved design standards, retrofit techniques, and new design criteria.

Emerging Explosive Threats

Emerging Explosive ThreatsDevelop projects to satisfy interagency and international requirements that address the adaptive threat associated with emerging explosives. Emphasize characterization of explosives and novel delivery techniques to combat their use in terrorist activities. Coordinate requirements received from the Homemade Explosives Working Group across appropriate CTTSO programs.

Vulnerability Identification

Vulnerability IdentificationDevelop predictive analysis software and decision aids to identify vulnerabilities and/or determine preventative courses of action. Emphasize pre-event planning and assessment of emerging threats.


Screening, Surveillance, and Detection

Screening, Surveillance, and DetectionDevelop technologies and techniques to survey and analyze facilities; improve situational awareness; detect, identify, and locate advancing threats; control access to critical assets; and neutralize confirmed threats. Emphasize automatic alerting, expeditionary kits, and exportable variants.


Integrated Solutions

Integrated Solutions​Integrate technologies into force protection solution packages that will improve the effectiveness of electronic security systems, reduce manning requirements, and offer increased affordability and survivability of operators and responders.
