Which is not a type of facility secured area?

In the context of facility security classifications, a secured area is often defined by various levels of control and access that are implemented to protect sensitive information, assets, or individuals. The types of secured areas typically include limited access, controlled, and restricted areas, each signifying varying degrees of access control and security measures based on the sensitivity of the information or assets being protected.

Limited access areas are those where entry is restricted to authorized personnel only. Controlled areas allow for more specific protocols around access that may vary by situation, while restricted areas are designed to safeguard highly sensitive resources, typically requiring stricter access protocols and monitoring.

The designation "critical," however, does not typically serve as a recognized category of secured area in the same manner as the others listed. Instead, critical might refer to a level of importance or urgency related to security rather than a formalized access control classification. It indicates something that may need immediate attention or a higher degree of security but does not serve as a specific type of secured area. As a result, "critical" stands out among the choices as it does not fit the established categories relevant to facility secured areas.
