There are also a few practices that it’s good common sense to follow at all times:

  •  Change the default password as soon as you log in to a new device for the first time
  •  Use strong, unique passwords for every device and change them regularly
  •  Ensure your devices are running the latest available firmware
  •  Don't enable remote access unless it's absolutely necessary
