What are security zones in the context of a facility?

In the context of a facility, security zones refer to designated areas that implement varying levels of security measures based on the sensitivity of the operations and the value of the assets within those areas. Each zone is tailored to address specific security risks and is managed differently to ensure that appropriate protection is maintained.

For instance, a facility may have a public access zone where minimal security is required, while more sensitive areas, such as data centers or research labs, may be fortified with advanced security protocols like access controls, surveillance, and alarms. This tiered approach allows organizations to allocate resources effectively and manage potential threats according to the potential impact on operations and security.

The other options do not accurately capture the concept of security zones. Areas without any security measures do not fall under the definition of a security zone, as they lack the very essence of security stratification. Locations meant solely for the storage of security equipment do not embody the layered security approach of different security zones. Lastly, restricting access only to top management does not represent a zone's purpose; it describes a potential access control policy, which is only one aspect of broader security zone management.
