Why may certain facilities still require credentials beyond the Common Access Card?

Certain facilities may require credentials beyond the Common Access Card to address area sensitivity concerns. In various environments, especially those involving sensitive information, critical infrastructure, or restricted areas, the level of access control must correspond to the security requirements of the specific area.

For instance, areas that contain classified information, critical assets, or particularly sensitive operations often mandate stricter access protocols to ensure that only authorized personnel can enter. This can include additional credentials such as background checks, special security clearances, or other forms of identification that signify a higher level of trust or local knowledge.

Using the Common Access Card alone may not provide sufficient assurance regarding an individual’s suitability for accessing such sensitive areas. Thus, requiring further credentials helps to maintain integrity and security within these controlled environments, ensuring that access is tightly regulated based on each area’s specific vulnerabilities and operational requirements.
