EMSEC and you Published May 9, 2013 By 48th Fighter Wing Cyber Surety Team ROYAL AIR FORCE LAKENHEATH, England -- Could you be the reason why our adversaries gain access to classified information? Do you know what your responsibilities are when working in a classified processing area? Knowing just a little bit about emission security or EMSEC could arm you with powerful tools to help prevent unauthorized access. EMSEC protection results from all measures taken to deny unauthorized personnel classified information that might be derived from signals produced by communications equipment. Compromising emanations are unintentional electronic signals which, if intercepted and analyzed by an adversary, would disclose the classified information transferred or processed by electronic communications systems. An EMSEC assessment is a tool the base EMSEC manager uses to determine the need for EMSEC countermeasures for equipment or systems in a facility that processes classified information. Factors considered during the assessment include classification level, the volume of information processed and the distance from areas outside of the installation's control. Before making any changes to an existing classified processing area or setting up a new area, you will need to contact your base EMSEC manager through your Information Assurance Officer.
