Does Tempest detects only the emission from the electron gun in the
monitor or can it get a usable "lock" on some other signals generated
within a computer?
As an example, can it grab the keystrokes? If the answer is yes, can
it do it:
a) rarely
b) occasionally
c) most of the time
d) almost all of the time
e) never
Could somebody knowledgeable in Tempest can rate the various
emissions from a computer?
(such as: keyboard, COM port, modem, lpt, video signal(from the
card), disk write, monitor emission, network comms, etc)
