An enterprise is upgrading its data center's physical security. The security audit revealed that while they have reliable electronic access controls for data center entry points, there is no measure in place to identify tailgating when these access points are used. Which physical security enhancement should be employed to mitigate this risk?
Installing mantraps at the entry points
Adding turnstiles at the access points
Upgrading to biometric authentication systems
Increasing surveillance camera coverage at entry points
Mantraps are designed to prevent tailgating by ensuring that only one person can enter or exit an area after authentication. They are typically structured as two sets of interlocking doors that only allow one door to be open at once, thus preventing an unauthorized person from following an authorized person into a secure area. Turnstiles, while useful for controlling flow, can still be susceptible to tailgating, especially if they are not full-height. Biometric systems strengthen the authentication process but do not, on their own, prevent tailgating. Surveillance cameras can record attempts at tailgating but do not actively prevent the act.
