Physical Security

Lock the aliens out!

Physical security is the first line of defense when it comes to physical access to an organization's critical assets. It often includes things like:

• biometric scanners (fingerprint, face, eyeball/retina)
• smart cards
• key fobs
• surveillance systems
  • video cameras
  • motion sensors
  • alarms
• backup power
• redundant cooling
• fire suppression systems

Physical security is often implemented by incorporating zones. Each zone is separated by its own barrier(s). One or more security mechanisms control entry and exit points through the barriers. Progression through each zone should be increasingly restrictive.

Designing Physical Security Systems

Physical security is implemented in a variety of cases and environments. It considers physical spaces, buildings, and landscapes to subtly promote inconspicuous security features in places like residential neighborhoods, commercial districts, schools, and other public spaces.

• Barricades and Entry/Exit Points
• Fencing
• Lighting
• Bollards
• Self-locking Locks

Sensors

Sensors provide a variety of detection and alerting capabilities. There are four main types of sensors:

• Infrared (motion detection) 
• Pressure (weight)
• Microwave (reflection)
• Ultrasonic (echolocation)
