Abstract:
In response to your September 1984 request, we have reviewed Department of Defense DOD and service adherence to national TEMPEST policy. TEMPEST refers to technical investigations and studies of compromising emanations from electronic information-processing equipment. Compromising emanations are unintentional intelligence-bearing signals which, if intercepted and analyzed, disclose classified information. National policy instructs federal agencies to protect classified information against such emanations. TEMPEST countermeasures-such as metal shielding, special wiring, and special equipment- are costly to implement. Total TEMPEST costs within DOD are unknown however, they are estimated at hundreds of millions of dollars annually.
