Part of TEMPEST - Red/Black Separation (Cables)
Associated with IA controls: ECTC-1
Failure to maintain proper separation could result in detectable emanations of classified information.
Check for a separation of at least 5 centimeters (2 inches) between any RED wire line and BLACK wire lines that exit the inspectable space (exit space not within a SCIF, Secret or above vault or secure room or Secret or above CAA) or are connected to an RF transmitter, or BLACK power lines. Requirement is mandatory for all OCONUS locations and certain specific CONUS locations based on geographic threat information. NOTE: This requirement is applicable in a tactical environment. The supporting CTTA should be contracted for specific separation requirements, which may be greater than the 5 cm distance reflected in this check.
