Explanation
Proximity readers (D) use RFID or smart card technology to authenticate individuals at entry/exit points, satisfying both the logging of entry/exit and the access control requirements for sensitive areas. Man traps (B) are double-door entry systems where only one door opens at a time, physically preventing tailgating-one person must be authenticated before the next can enter. Together these two controls address all three stated requirements. Discretionary Access Control (A) is a logical access control model for data/systems, not a physical entry control. Visitor logs (C) track visitors manually but do not enforce access control or prevent tailgating. Motion detection sensors (E) detect movement but do not control, log, or authenticate entry, nor do they prevent tailgating.
