Magnetic Pulse for Computer Hacking

On this computer site, at the bottom, is a graph which simply explains how electromagnetic pulse is used to hack and access computers:

It may seem ridiculous to worry about atomic detonation compromising your system but the same type of attack can be accomplished using a small but powerful, portable wideband transmitter. It has been shown that most systems are vulnerable to electromagnetic pulse. The military has known about this type of attack for years and has implemented a policy of system hardening. System hardening consists of the various means listed in the table above. Some newer multi-processor machines have built-in error checking and the ability to use the result of an alternate device if one fails to pass validation tests.

As we reach ever faster speeds of processing and fill the air with bands of signals from cell phones and other such portable devices we risk interference between these devices. A simple way to demonstrate this is to place an older motor driven alarm clock near your computer monitor and plug it in while watching the screen.
