Bilgisayar manyetik alanından bilgi çalma ve Tempest

Tempest(Kısa süreli elektromanyetik darbe yayılım standardı)

havada yayılan elektromanyetik dalgaları kopyalayarak , ağa bağlı olmayan bilgisayarlardaki bilgileri ele geçirmek de çok zor değil. Bu korsanlığın önüne geçmek TEMPEST yöntemiyle mümkün.

What is TEMPEST?

TEMPEST is a U.S. government code word that identifies a classified set of standards for limiting electric or electromagnetic radiation emanations from electronic equipment. Microchips, monitors, printers, and all electronic devices emit radiation through the air or through conductors (such as wiring or water pipes). An example is using a kitchen appliance while watching television. The static on your TV screen is emanation caused interference. (If you want to learn more about this phenomena, a company called NoRad has an excellent discussion (X) of electromagnetic radiation and computer monitors (and Chomerics has a good electromagnetic interference 101 page), that you don’t need to be an electrical engineer to understand. Also, while not TEMPEST-specific, a journal called Compliance Engineering (O), typically has good technical articles relating to electromagnetic interference. There’s also the Electromagnetic Compliance FAQ.)
