What issue does “tailgating” present in access control?

• A. It restricts access for authorized users
• B. It involves unauthorized entry by following an authorized user
• C. It refers to delays in access verification
• D. It enhances monitoring of access points

Answer: (B)

Tailgating presents a significant threat in access control systems because it involves unauthorized individuals gaining access to secure areas by closely following an authorized person who has legitimate access rights. This can happen in various environments, such as secure buildings or protected facilities, where bad actors take advantage of the trust and courtesy extended by authorized users. In situations where access is controlled by keycards or biometric scanners, a common scenario is when an authorized individual scans their access credential to enter but does not ensure that the door closes completely behind them. An unauthorized person may then quickly follow through the open entry point, thereby bypassing any verification mechanisms in place. This issue emphasizes the necessity for robust physical and electronic security measures that can prevent not only unauthorized access but also raise awareness of the importance of not allowing others to enter without verification of their credentials. While other options may touch on related subjects, they do not directly address the core issue of unauthorized access through following someone with legitimate access rights.
