Physical Security Flashcards
(45 cards)
Measures taken to protect tangible assets, like buildings, equipment, and people, from harm or unauthorized access.
Physical Security
Short, sturdy vertical posts, made of steel or concrete, designed to manage, control, or prevent access by vehicles to an area or structure by redirecting vehicular traffic.
Bollards
Barriers/structures that are made of interconnected panels, posts, wire, or boards that are erected to enclose a space or separate areas.
Fences
Organized strategy or setup designed to observe & report activities in a given area. Maintain the security & safety of facilities, including business, home, or commonly used public areas.
Surveillance System
Double-door system, designed with two electronically controlled doors that ensures only one door is open at any given moment of time.
Access Control Vestibule
Involves two people, with & without access, entering a secure area. A person with legitimate access intentionally allows another person without authorization to enter a secure area with them.
Piggybacking
Occurs whenever an unauthorized person closely follows someone with legitimate access to the secure space without their knowledge or consent.
Tailgating
What purposes does a fence serve?
- Provides a visual deterrent by defining a boundary that should not be violated by unauthorized personnel.
- Establish a physical barrier against unauthorized entry.
- Delays intruders, which helps provide security personnel a longer window to react.
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
Involves the direct confrontation or attack of security personnel
Confronting Security Personnel
Brute force attack that uses a car, truck, or other motorized vehicle to ram into the organization’s physical Security barriers.
Ramming a Barrier with a Vehicle
What four categories make up surveillance?
- Video Surveillance
- Security Guards
- Lighting
- Sensors
Can move the camera or its angle to better detect issues during an intrusion.
Pan-Tilt-Zoom (PTZ)
Flexible & adaptable forms of surveillance that organizations use.
Security Guards
Crucial for conducting effective surveillance using both video and security guards.
Lighting
Devices that detect & respond to external changes in the environment & convert the information into readable signals or data.
Sensors
What are the four categories of sensors?
- Infrared
- Pressure
- Microwave
- Ultrasonic
Detect changes in infrared radiation that is emitted by warm bodies like humans or animals.
Infrared Sensors
Activate when a specified minimum amount of weight is detected on the sensor that is embedded into the floor or a mat.
Pressure Sensors
Detect movement in an area by emitting microwave pulses & measuring their reflection off moving objects.
Microwave Sensors
Measure the reflection of ultrasonic waves off moving objects.
Ultrasonic Sensors
Blocking the camera’s line of sight (paint on camera, etc).
Visual Obstruction
