Update Information
Detection and Deployment Tools and Guidance
Manage the software and security updates you need to deploy to the servers, desktop, and
mobile systems in your organization. For more information see the TechNet Update Management
Center. The Microsoft TechNet Security Web site provides additional information about
security in Microsoft products.
Security updates are available from Microsoft Update, Windows Update, and Office Update.
Security updates are also available from the Microsoft Download Center. You can find them
most easily by doing a keyword search for "security update."
Finally, security updates can be downloaded from the Microsoft Update Catalog. The Microsoft
Update Catalog provides a searchable catalog of content made available through Windows
Update and Microsoft Update, including security updates, drivers and service packs. By
searching using the security bulletin number (such as, “MS07-036”), you can add all of the
applicable updates to your basket (including different languages for an update), and
download to the folder of your choosing. For more information about the Microsoft Update
Catalog, see the Microsoft Update Catalog FAQ.
Detection and Deployment Guidance
Microsoft has provided detection and deployment guidance for this month’s security updates.
This guidance will also help IT professionals understand how they can use various tools to
help deploy the security update, such as Windows Update, Microsoft Update, Office Update,
the Microsoft Baseline Security Analyzer (MBSA), the Office Detection Tool, Microsoft
Systems Management Server (SMS), and the Extended Security Update Inventory Tool. For
more information, see Microsoft Knowledge Base Article 910723.
Microsoft Baseline Security Analyzer
Microsoft Baseline Security Analyzer (MBSA) allows administrators to scan local and
remote systems for missing security updates as well as common security misconfigurations.

For SMS 2.0 and SMS 2003, the SMS SUS Feature Pack (SUSFP), which includes the Security
Update Inventory Tool (SUIT), can be used by SMS to detect security updates. See also
Downloads for Systems Management Server 2.0.
For SMS 2003, the SMS 2003 Inventory Tool for Microsoft Updates (ITMU) can be used by
SMS to detect security updates that are offered by Microsoft Update and that are
supported by Windows Server Update Services. For more information about the SMS 2003
ITMU, see SMS 2003 Inventory Tool for Microsoft Updates. SMS 2003 can also use the
Microsoft Office Inventory Tool to detect required updates for Microsoft Office
applications. For more information about the Office Inventory Tool and other scanning
tools, see SMS 2003 Software Update Scanning Tools. See also Downloads for Systems
Management Server 2003.
System Center Configuration Manager 2007 uses WSUS 3.0 for detection of updates. For
