Intelligence-Bearing Emanations

Intelligence-bearing emanations can be in the form of electrical, electromagnetic, mechanical or acoustic energy. Information-processing devices generally produce electrical and electromagnetic signals field around themselves and these emanations can carry all sorts of intelligence information. Such intelligence-bearing emanations are not encrypted and therefore may disclose passwords and other critical information in plain text form. Intelligence-bearing emanations are typically unintentional but can be compromising if they are intercepted and retrieved by a malicious hacker.
