True, "Tempest" refers only to such shielding. However, a system CAN be
shielded from EMP. It requires diligently applying a shield around *EVERYTHING*:
the equipment to be protected, the power lines from the UPS, the data lines
between terminals and computers, the UPS itself and connecting this shield
to earth ground. Thus shielded, the system should be safe from EMP.
