What does "perimeter security" refer to?

"Perimeter security" primarily focuses on the measures implemented to protect the outer boundaries of a property. This includes the use of physical barriers, such as fences and walls, as well as surveillance systems like cameras and motion detectors. The goal of perimeter security is to deter unauthorized access and enhance the overall safety of a location by establishing a controlled boundary. By securing the perimeter, organizations can minimize risks and protect their internal assets and personnel from external threats.

The other options address different aspects of security. Measures taken to ensure employee safety focus on personal well-being within the workplace rather than the boundaries of a property. Strategies to manage internal security incidents pertain to handling issues that occur within the organization rather than at its exterior. Technologies used for data protection relate specifically to safeguarding digital information rather than the physical security of a property. This distinction makes it clear why the protection of outer boundaries is the essence of perimeter security.
