Physical Security Planning And Implementation Practice Test

An active barrier is designed to require intervention from personnel or equipment before granting access to individuals or vehicles. This type of barrier typically includes systems such as gates that must be opened manually or through specific control mechanisms, such as key cards or remote controls. This approach allows for a controlled entry point where security measures can be enforced, ensuring that only authorized individuals or vehicles gain access. In contrast, a passive barrier functions without any action needed from personnel; it remains in place and does not allow passage unless physically breached. An automatic barrier, like a gate that opens automatically when approached, also does not require personnel intervention because it operates based on signals or sensors. A security fence, while a physical barrier, provides general boundary protection and does not specifically control access in the same interactive way as an active barrier. Therefore, the requirement for active involvement to allow passage distinguishes active barriers from the other options.
