Title:
  OpenSSH server sshd_config PermitRootLogin -> NO

Status in openssh package in Ubuntu:
  Opinion

Bug description:
  Ubuntu does not use the root account directly so the PermitRootLogin
  directive in sshd_config should be set to "no" by default.  This
  policy is backed by the upstream documentation:

      "For security reasons, it is bad practice to log in as root during regular
       use and maintenance of the system.  Instead, administrators are encour-
       aged to add a ``regular'' user, add said user to the ``wheel'' group,
       then use the su(1) and sudo(8) commands when root privileges are re-
       quired.  This process is described in more detail later."
      From : http://www.openbsd.org/cgi-bin/man.cgi?query=afterboot

  Bruteforce attacks against the root account are now continual and have been for several years:

  If there are shortcomings in the the documentation and guides for sudo
  or how to use key-based autentication, then they should be addressed
  there so that this default setting can be set properly.
