PE-3 (2): Facility / Information System Boundaries

The organization performs security checks [Assignment: organization-defined frequency] at the physical boundary of the facility or information system for unauthorized exfiltration of information or removal of information system components.

Supplemental

Organizations determine the extent, frequency, and/or randomness of security checks to adequately mitigate risk associated with exfiltration.
