Hello All and thank you for your input,

I have read your answers and came down with the following ideas:

I) As of the moment, Knoppix is patched and somewhat secure to the known attacks/exploits from the net. Thus as long as one keeps the physical access to the computer safe/restricted, the outside (to the internet) can be considered to be safe.

2) Firewall is needed only if one runs a service or keeps TCP port open.

3) The largest problem with Knoppix is the root access (which by default has no password ? I have tried 'su' and gained root level without any password). I very much appreciate the 'rootpassword' parameter at the bootup, it probably saved me hours of work of figuring out how I would make sure that the root password would be something of my choice.

Thank you, I will look into this tonight and update the thread with any additional questions that may arise. If anyone else who is reading this thread wishes to act keypoints about Knoppix's default security and security issues that may arise with fresh bootup of Knoppix on any random machine, please dont be shy and contribute.

PS: The email is changed temporarily.
