Kubuntu disables the root user by default. That's why we use sudo to
execute programs that need administrative access, and sudo -i to
actually switch to the root user. There literally is NO password for
root, so while the user exists, the account can NOT be hacked.

You of course sitll have to worry about your own account being hacked,
but then we go back to the windows scenario of them having to guess
both an administrative ID ( the first user you create is in the
sudoers group, none of the rest are IIRC ) and the password for said
admin account.

Hope this helps.
