 ===== Disable Ctrl-Alt-Delete =====
-Anyone that has physical access to the keyboard can simply use the Ctrl+Alt+Delete key combination to reboot the server without having to log on.  Sure, someone could simply unplug the power source, but you should still prevent the use of this key combination on a production server.  This forces an attacker to take more drastic measures to reboot the server, and will prevent accidental reboots at the same time.

+===== Setup the correct time zone (optional, but highly-recommended) =====
 Having the right time zone is a requirement for proper security of the server.  ShareWiz security standards require the time zone to be set to GMT.  This standardizes time in the system and prevents security issues which may occur with unusual time movements.  It also ensures that logs files are consistent.
