Disabling Root On Linux or Unix

LinuxSecurity.com: Loosely following up on a few previous posts regarding securing Linux and Unix and even more fun with Unix and Linux security, today we're going to look at something vaguely security-related, and also vaguely scary ;) It has to do with the root account (or user id 0) and security hardening. I've got nothing against either, so this won't be an insane diatribe, but (especially, no offense to Ubuntu) with more Linux distro's coming straight out-of-the-box with root disabled, I see the issue of security and the root user get a little confused. A lot ;) Any Ubuntu user knows that the root account is disabled by default because of security concerns. But if we have strong passwords and firewalls do we really need to disable the root account?
