What type of zone is typically monitored for perimeter security?

The type of zone typically monitored for perimeter security is the perimeter follower zone. This zone focuses on monitoring the outermost boundaries of a facility or location, which is critical for detecting unauthorized access or breaches. The perimeter follower zone is designed to provide alerts and responses to activities occurring around the perimeter, which acts as the first line of defense against potential threats. By closely monitoring this area, security systems can identify attempts to gain unauthorized access before they penetrate deeper into the secured environment.

In contrast, other zones like access control zones are primarily concerned with managing and monitoring access to specific areas or systems rather than the outer perimeter. External zones might refer to areas that are outside the immediate influence of the security systems, such as areas not actively monitored. Virtual zones pertain to network boundaries and cybersecurity rather than physical security perimeters. Each of these plays a different role in an overall security strategy but does not specifically focus on perimeter security as effectively as the perimeter follower zone does.
