What are the categories of physical security controls?

The correct choice highlights the categories of physical security controls as deterrent, detective, and corrective controls. This classification is essential in understanding how security systems function effectively.

Deterrent controls are designed to prevent security incidents by discouraging potential threats from occurring. For instance, visible security measures like surveillance cameras and security personnel act as a deterrent to potential intruders, making them think twice before attempting to breach security.

Detective controls are implemented to identify and detect security incidents when they occur. These can include alarm systems, motion sensors, and surveillance cameras that not only act as deterrents but also gather information about security breaches, enabling a timely response.

Corrective controls are measures taken to respond to an incident after it has occurred, aiming to restore systems to normal operation and prevent future occurrences. These might include actions such as reviewing security policies, enhancing physical barriers, or conducting employee training sessions after an incident to address weaknesses.

This classification helps organizations structure their physical security strategies comprehensively. Each type plays a significant role in creating a robust security environment that minimizes risks and mitigates damage from potential threats.
