• Give a BIOS password on the server, of course we do not want to subject the server hack with most simple way, namely through the boot disk cdrom / floppy. (Actually, it could also remove cdrom or floppy drive)
• Configuring the minimum password length that is used for the user. To be more difficult to guess password. in the / etc / login.defs, remove comment mark on the line PASS_MIN_LEN and then provide a minimum number of character you want to use, example:

  root@getuxcom: ~ # vi /etc/login.defs
PASS_MIN_LEN = 10 (value added)

• Should never login as root if not actually in a state of forced, and never leave the computer without logging out. logout can be done by typing the command exit or [ctrl + d]
• Setting the login timeout for the root account. This will be very useful when administrators forget to logout or leave the computer for too long. edit the file /etc/profile, then add the line TMOUT. Example:
  root@getuxcom: ~ # vi /etc/profile
TMOUT = 7200 (line added)
