TEMPEST in Your Tea Pot ?

I had a fascinating conversation with an old friend over the Holidays and had to give him a plug.

Have you ever heard of TEMPEST ?

It refers to the odd habit that Electronic devices have of leaking radiation like an antenna. If you are running a blender, who cares? If however, it is your Computer, or Monitor, or Server, you are unwittingly broadcasting everything you are doing.

If you are surfing the Internet, no big deal, but if it is your Server, with your businesses entire financial information on it you may be in big trouble.

He described how his firm was brought in to determine how a certain business was losing $1,000.000.00 a month and found out it was some shady characters with a high gain antenna sniffing the company CFO’s wireless keyboard.

I would urge anyone that is serious about computer security to look beyond the Firewalls and Routers and think hard about a product like this.

Nice chatting with you again John.
