Use an etch-a-sketch. Etch-a-sketch displays are not vulnerable to power-line denial-of-service attacks or fires. They *are* vulnerable to data loss during earthquakes or if physical access is obtained, however most operating systems running on standard hardware are also vulnerable to attacks of this nature. They are not vulnerable to remote electronic eavesdropping, as they emit no power signature, in fact no emissions of any kind. I am not familiar with TEMPEST specifications, however, and can not claim this level of security. ~mark From: Robert Watson <robert@cyrus.watson.org>
Use a toaster oven. [...] Toaster ovens may be vulnerable to a remote denial of service attack involving manipulation of power lines -- however, most operating systems running on standard hardware are also vulnerable to this attack.
