I don't recall if we had a discussion here about how to have "strong" memorable passwords. I prefer keyboard patterns, for example, 7ujmghjkl or 8uhb6yjm or some kind of keyboard pattern. You can stick in a "hold shift down" for any part of it. You can do a circle, a box, plus sign, X, 2 per row, 3 per row, 2 per row going up rows (nmhjyu67). All very easy ro train your fingers to do.

I intend to speak with my friend about how he protected access to his written down password. I do know that he did not log on to this system until after his daughter broke in. I didn't think to take out the floppy as I did the modem. Perhaps that will help in the future. Again, thanks for your insights. Edward J.

While I appreciate the praise, neither Immunix nor SELinux provide security against physical access. The problem is below the operating system, in the BIOS: by default, the hardware/BIOS looks at removable media (floppy, CD, DVD) ahead of looking at the hard drive to boot from. To 0wn the machine, just insert a malicious disk and reboot. > Open Source Linux Rules Linux, security-enhanced or not, is subject to the same threat. To prevent this attack, while also offering physical access (i.e. in a public kiosk or a school lab) you have to physically block the removable media. For instance, you remove the CD and floppy drives from the machine, and then encase the whole box in a locked cabinet so the attacker can't install their own drives. Protecting a home PC from your kids is flat out impossible. If it still is important to have this protection, get a door lock.
