Detection and localization of technical channels of information leakage

Abstract

A technical channel of information leakage (TCIL) is a physical channel (acoustic, electromagnetic, electrical), which allows access to be obtained to an information object with the help of technical means [1, 2]. Protection against information leakage via technical channels (usually called Technical Surveillance Countermeasures) is a complicated multi-pronged problem requiring the fulfillment of the organizational and engineering action complex. An important stage of similar actions is the search of electromagnetic channels of information leakage in radio wave range, which propagate outside the monitored area. © 2009 Springer-Verlag US.
