So all, that is shown here shows:
- If you had to put data on a computer, where the physical access isn't restricted: Encrypt them! That is the only way to protect your data!
- If possible put your data on a server, where your server is somewhere, where nobody evil can get. But that isn't really save, because you cannot know, who is "evil" and the server can be hacked!

The knoppix CD is nice, but If you want a "hacker tool", there are much better things.

But knoppix is really really cool to show some "dumb" people, what their great security is "worth". Security is something, a lot of people didn't think about.

I burned a lot of cd's in the last days and gave them to a lot of coworker. knoppix is really usefull and saved us a lot of work.
(e.g. starting a os/2 server which has a destroyed config.sys. The server didn't start any more. Or when windows doesn't start any more and the computer will be "rebuild" again, it is really easy to copy some data. In both cases, there would be other possibilities, too, but it was really easy to simply insert Knoppix.)
