Short name referring to investigation, study, and control of compromising emanations from information system equipment. The study and control of electronic signals produced by various types of electronic hardware, such as computers, televisions, phones, and so on. Its primary goal is to prevent EM and RF radiation from leaving a strictly defined area so as to eliminate the possibility of external radiation monitoring, eavesdropping, and signal sniffing. The study and control of spurious electronic signals emitted from electronic equipment. TEMPEST is a classification of technology designed to minimize the electromagnetic emanations generated by computing devices. TEMPEST technology makes it difficult, if not impossible, to compromise confidentiality by capturing emanated information.
