Tracking down the hackers. A do it yourself kit. I'm Fred Fishkin with Bloomberg Bootcamp. Personal firewalls are becoming more necessary and more popular these days... and for good reason. With always on... cable or DSL connections to the Internet... your computer system at home is more vulnerable. Now comes a different kind of firewall from a company called Sharp Technology. Hack Tracer...

"Hack Tracer is an intrusion detection product much like any other kind of firewall system you would see on the market and it's geared towards home users and small businesses. So what we do first and foremost is protect the user's PC from hacking attempts by outside people. Anything that comes into the machine is treated as suspect and we block that attack but then we add a twist. We back trace the hacker to determine their physical location. The user can bring up a world map and watch the traffic route from your computer to the hacker's computer and then you can use that data to report the hacker to our centralized server and potentially report that hacker to his ISP."

To hopefully knock him off the Net says Michael Pierce of Sharp Technology. How common are hacker attacks... .you'd be surprised and maybe frightened...

"You would be amazed to see just how much you're being touched on by people. If you install our product, we have kind of a tag line... we say... no hack, money back guarantee."

You can find the software for under forty dollars at hacktracer.com. Bootcamp, I'm Fred Fishkin, Bloomberg News.
