The quest for illicit intelligence is a never-ending threat; from criminals trying to obtain information for financial gain, to sophisticated state-sponsored adversaries looking for political and military gains. While we do not always know what kind of threats are around us, a robust security policy encompassing physical security, cyber security and protection from electronic surveillance is needed to ensure secrets remain secret. The security of your building, your Sensitive Compartmented Information Facility (SCIF), your private conversations, your plans and secrets can all be compromised by surveillance devices; from small, inexpensive GSM/UMTS bugs to bespoke devices created by state actors.
