What Does RED Baseband Signal Mean?
A RED baseband signal is a type of compromising emanation, or intelligence-bearing signal that could disclose national security information if intercepted. It is a term used by National Security Telecommunications and Information Systems Security which, under NSTISSI No. 7000, defines these signals as unintentional intelligence-bearing emanations, or TEMPEST, which may be released by electronic and electromechanical information-processing equipment.
