Tempest in computing terms has nothing to do with any impending storm or the lull before it: it is simply a technique for keeping all the stray electromagentic radiations given off by any electronic piece of equipment safe inside the case, so that they do not reach the ears of eavesdroppers armed with equipment that for example can pick up character by character text being keyed into an unshielded micro. And if you do business with Uncle Sam, Tempesting your kit is pretty much a sine qua non, so Synoptics has introduced a Tempest version of its fibre optic Lattisnet products, with the help of specialist Tempest Technologies Inc of Herndon Virginia. It will manufacture shielded enclosures for Lattisnet premises and department concentrators and fibre optic transceivers. The Tempest enclosure design allows concentrators and transceivers to be field-upgraded to the full Tempest specifications or enclosed prior to shipment.
