A guard checking IDs at the gate of an installation is a good example of what type of security?

The identification checks performed by a guard at the gate exemplify point security because they focus on a specific location or point of entry into the installation. Point security measures are designed to protect a defined area from unauthorized access and often involve physical barriers and personnel presence to control and monitor who is allowed entry. In this context, the guard is a crucial element ensuring that only authorized individuals can access sensitive areas within the installation, thereby maintaining security at that specific point.

Point security is particularly effective for controlling access to facilities, as it allows for direct observation and intervention at places where entry is most likely. It complements other security measures but operates at the specific juncture where access occurs, distinguishing it from broader, area-wide security measures. This targeted approach is essential for preventing unauthorized entry, thereby enhancing the overall security posture of the installation.
