TEMPEST is a U.S. National Security Agency specification and a NATO certification referring to spying on information systems through leaking emanations, including unintentional radio or electrical signals, sounds, and vibrations.
TEMPEST covers both methods to spy upon others and how to shield equipment against such spying. The protection efforts are also known as emission security (EMSEC), which is a subset of communications security (COMSEC).
Starting tomorrow there will be a five part series on TEMPEST and side channel attacks.

I worked in AF TEMPEST from 1974 to 1982. TEMPEST was never an acronym while I was working it. It was, as far as I know, just a name.

After NSA & Navy schooling I did instrumented Tempest tests for the Navy from 1967 through 1985. Tempest was not an acronym. Leave it to the bureaucrats to think one up.

Although Telecommunications Electronics Material Protected from Emanating Spurious Transmissions (TEMPEST) is found on several websites, none of these sources are government. Therefore the acronym explanation has been removed. Thank you for your comments.
