Physical Security Flashcards
Security+
What is the primary role of a security guard?
To provide physical protection at the reception area of a facility and validate employee IDs.
What does two-person integrity/control aim to achieve?
To minimize exposure to an attack by ensuring no single person has access to a physical asset.
What details are typically found on an access badge?
Picture, name, and other identifying details; it must be worn at all times and is electronically logged.
How does increased lighting contribute to security?
More light means attackers are less likely to approach; it’s easier to see when well-lit.
Why are non-IR cameras more effective in well-lit areas?
They can see better in adequate lighting conditions, enhancing visibility for security.
What should be considered when designing lighting for security purposes?
Overall light levels, lighting angles for facial recognition, and the need to avoid shadows and glare.
What does an infrared sensor detect?
Infrared radiation, functioning in both light and dark environments; commonly used in motion detectors.
How do pressure sensors work?
They detect changes in force, often used in floor and window sensors.
What is the primary function of microwave sensors?
To detect movement across large areas.
How do ultrasonic sensors operate?
They send ultrasonic signals and receive reflected sound waves to detect motion and collisions.
