What is the purpose of perimeter barriers in security?

1. They allow free access to all personnel.

2. To restrict access and shield activities from observation.

3. To establish welcome areas for visitors.

4. To categorize different areas within installations.

The correct answer is: To restrict access and shield activities from observation.

The purpose of perimeter barriers in security is primarily to restrict access and shield activities from observation. These barriers serve as the first line of defense in safeguarding property, assets, and sensitive information by controlling who can enter or exit a particular area. They create a physical separation between secure zones and public spaces, significantly deterring unauthorized access and potential threats. By limiting visibility, perimeter barriers also protect the activities occurring within the secured area from being easily observed by outside parties. This concealment helps in reducing the risk of espionage, theft, and other illicit actions. Furthermore, the structure of these barriers can vary, including fences, walls, gates, and other physical deterrents, each designed for monitoring and controlling access effectively. The other options do not accurately capture the primary role of perimeter barriers. Allowing free access would undermine their effectiveness in providing security, while establishing welcome areas and categorizing spaces is more about accessibility and management rather than the core security function of protecting a perimeter.
