In today's environment of exploit seekers, Patch and Update Management is as important as Anti-Virus Management.  Microsoft Software Update Services (SUS) is designed to greatly simplify the process of keeping Windows-based systems up-to-date with the latest critical updates. SUS enables administrators to quickly and reliably deploy critical updates to their Windows 2000-based servers as well as desktop computers running Windows 2000 Professional or Windows XP Professional.

The best part of SUS is that it's a free download.  Once SUS is installed, it only requires a periodic review and approval of updates.  ITS offers SUS at a one-time charge for installation.  Periodic update approval is included with your maintenance agreement or can be purchased separately.  If you wouldn't think of allowing your environment to be without an anti-virus solution, electing to use SUS is an easy decision.
