J.Dion Sec. 4 Physical Security Flashcards
(35 cards)
Measure taken to protect tangible assets, like buildings, equipment, and people, from harm or unauthorized access.
Physical security
Short , sturdy vertical posts designed to control or prevent access by vehicles to an area or structure.
Bollards
Barriers that are made of posts, wire, or boards that are erected to enclose a space or separate areas.
Fences
Organized strategy or setup designed to observe and report activities in a given area.
Surveillance system
Double-door system with two electronically controlled doors that ensure only one door is open at any given moment.
Access control vestibule
Involves two people, with and without access, entering a secure area.
Piggybacking
Occurs whenever an unauthorized person closely follows someone with access without their knowledge or consent.
Tailgating
Fences prevent unauthorized
people from accessing area
Bollards prevent
vehicles from driving into buildings
Attack where access to a system is gained by trying all of the possibilities until breaking through.
Brute Force
Act of gaining unauthorized access to a space by physically breaking or bypassing its barriers, such as windows, doors, or fences.
Forcible entry
Involves manipulating security devices to create new vulnerabilities that can be exploited.
Tampering with Security Devices
Organized strategy or setup designed to observe and report activities in a given area.
Surveillance system
What are the four main categories of surveillance?
Video surveillance
Security guards
Lighting
Sensors
Devices that detect and respond to external changes in the environment and convert the information into readable signals or data.
Sensors
What are the four categories of sensors?
Infrared sensors
Pressure sensors
Microwave sensors
Ultrasonic sensors
Sensors that detect changes in infrared radiation that is emitted by warm bodies like humans or animals. These sensors are effective in low light or dark conditions.
Infrared Sensors
Sensors that are activated when a specified minimum amount of weight is detected on the sensor that is embedded into the floor or a mat.
Pressure sensors
Sensors that detect movement in an area by emitting microwave pulses and measuring heir reflection off moving objects.
Microwave sensors
Sensors that measure the reflection of ultrasonic waves off moving objects.
Ultrasonic sensors
Double-door system that is designed with two doors that are electronically controlled to ensure that only one door can be opened at a given time.
Access control vestibule
Physical security control that is designed to secure entryways by restricting and regulating access to a particular space or property.
Door locks
Occurs any time the biometric system authenticates a user as valid, even though that person should not have been granted access to they system.
False Acceptance Rate (FAR)
Occurs anytime the biometric system denies a user who should have been allowed access to the system.
False Rejection Rate (FRR)
