Doors come in many different styles and functionalities, such as vault doors or industrial doors. When two doors are used to stop an individual from getting in or out what are being created?
Explanation
Answer: C - When two doors are used to stop an individual from getting in or out, a mantrap is being created. A mantrap is a small room with two doors. The first door is locked. A person is identified and authenticated by a security guard, biometric system, smart card reader, or swipe card reader. Once the person is authenticated and access is authorized, the first door opens and allows the person into the mantrap. The first door locks and the person are trapped. Once inside the mantrap, the individual is authenticated again before the second door opens to allow entry into the facility. Some of these systems use weight measures to ensure only one person is inside the trap to counter piggybacking attempts.
