Under what condition are intrusion sensors to be installed for a SAPCA?

The correct choice regarding the installation of intrusion sensors for a Special Access Program Central Area (SAPCA) is when it includes a boundary wall of the parent Special Access Facility (SAPF) or Sensitive Compartmented Information Facility (SCIF).

This condition is significant because the presence of a boundary wall establishes a clear physical perimeter that needs to be secured against unauthorized access. Incorporating intrusion sensors in such locations enhances the overall security posture of the facility, effectively protecting sensitive information and material from potential threats. The sensors can detect unauthorized breaches, ensuring that the integrity of the protected space is maintained.

While factors like the number of visitors, the sensitivity of the information, or whether the area is indoors may influence security measures, they do not dictate the foundational necessity for intrusion sensors in the same way that the establishment of a physical boundary wall does. The boundary wall serves as a critical delineation for security protocols, making it essential to have intrusion sensors to monitor and respond to potential breaches along this perimeter.
