. We worked in a place called a SCIF – a Sensitive Compartmented Information Facility. The SCIF was literally cut off from the rest of the world. The Internet couldn’t be accessed from inside the SCIF. Rooms were shielded so cell phones wouldn’t work. (Some such devices weren’t allowed in the SCIF for that matter. Obviously, you wouldn’t want an iPod with a built-in camera in a SCIF.)
