Physical security controls are used to restrict access to a building, room, or equipment. The different types of physical security controls include identification cards, biometric devices, proximity readers, and video cameras.
A false positive is a situation where a security control incorrectly identifies someone as authorized to access a particular area or equipment when they are not. This can happen due to a malfunction in the control or due to a person's physical characteristics changing over time, such as in the case of biometric devices.
Out of the four physical security controls listed, a proximity reader is the most likely to be susceptible to a false positive. A proximity reader is a device that reads a badge or card that contains a radio-frequency identification (RFID) tag. These tags contain a unique identifier that the reader uses to grant or deny access.
The reason why proximity readers are more susceptible to false positives is that they rely solely on the RFID tag to identify the user. If someone else has a badge with a similar RFID tag or if the tag malfunctions, the reader may incorrectly grant access to the wrong person.
In contrast, biometric devices and video cameras are less likely to have false positives as they capture unique physical characteristics of the person such as fingerprints, iris, and facial features. Identification cards are also less susceptible to false positives as they contain a photo of the authorized person and are usually checked by a security guard or receptionist before granting access.
Therefore, the correct answer to the question is C. Proximity reader.
