Physical Control Space/physically Controlled Space (PCs)
  • The spherical space surrounding electronic equipment used to process information under sufficient physical control to stop intercept of compromising emanations. It is usually expressed in meters and can be controlled by fences, guards, patrols, walls, and so forth. The exact method of securing the PCs may vary depending upon resources available. (AFR 205-16; OPNAVINST 5239. l A)
