Which of the following is an example of a physical security measure?

CPTED, which stands for Crime Prevention Through Environmental Design, is indeed a physical security measure. It involves the strategic design of physical environments to reduce opportunities for crime and enhance security. CPTED encompasses approaches such as improved landscaping, natural surveillance, and territorial reinforcement, all aimed at creating spaces that deter criminal activity by making potential offenders feel less comfortable and more visible.

This approach is grounded in the idea that the environment can influence human behavior. By incorporating design features that promote safety and visibility, CPTED effectively serves as a deterrent against crime, making it an integral part of physical security strategies.

In contrast, options like security personnel, camera surveillance, and background checks also play crucial roles in overall security but fall into different categories. Security personnel provide a human presence that can respond to threats, while camera surveillance aids in monitoring and documenting activities, and background checks are essential for assessing the trustworthiness of individuals and employees. These are proactive and reactive measures but do not specifically involve the design and layout of physical spaces like CPTED does.
