What is one example of an active technical control in physical security?

An example of an active technical control in physical security is the presence of security guards at access points. This choice represents a proactive measure designed to monitor, control, and enforce entry and exit in secured areas. Security guards actively engage with individuals seeking entry, verifying credentials and observing behaviors, which can deter unauthorized access and respond immediately to potential threats.

Active controls are those that require direct action to influence security, as opposed to static measures that merely set policies or record information. In this case, security guards not only serve as a visual deterrent but also take action by questioning individuals, managing crowds, and responding to incidents in real-time. This active involvement is crucial for ensuring a secure environment, making the presence of security guards a strong example of physical security control.

Other options, while relevant to maintaining security, fall under different categories. For instance, a visitor management program and logbooks are more passive controls, as they often require individuals to fill out forms or check in but do not actively monitor behavior or enforce access rules. A physical security policy outlines the guidelines and procedures related to security but lacks the active enforcement component that characterizes the role of security guards.
