Detection and Deployment Tools and Guidance

Security Central

Manage the software and security updates you need to deploy to the servers, desktop, and mobile computers in your organization. For more information see the TechNet Update Management Center. The TechNet Security Center provides additional information about security in Microsoft products. Consumers can visit Security At Home, where this information is also available by clicking “Latest Security Updates”.

Security updates are available from Microsoft Update, Windows Update, and Office Update. Security updates are also available at the Microsoft Download Center. You can find them most easily by doing a keyword search for "security_patch." Finally, security updates can be downloaded from the Windows Update Catalog. For more information about the Windows Update Catalog, see Microsoft Knowledge Base Article 323166.

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), the Extended Security Update Inventory Tool, and the Enterprise Update Scan Tool (EST). For more information, see Microsoft Knowledge Base Article 910723.

Microsoft Baseline Security Analyzer and Enterprise Update Scan Tool

The Microsoft Baseline Security Analyzer (MBSA) allows administrators to scan local and remote systems for missing security updates as well as common security misconfigurations. For more information about MBSA, visit Microsoft Baseline Security Analyzer.

When MBSA 1.2.1 cannot support detection for a specific security update, Microsoft releases a version of the Enterprise Update Scan Tool (EST) for that specific security update. For more information about EST, visit Enterprise Update Scan Tool.

Note After October 9, 2007, the MSSecure.XML file used by MBSA 1.2.1 will no longer be updated. After this date, no new security updates will be added to the MSSecure.XML file used by MBSA 1.2.1 and no new versions of the Enterprise Scan Tool will be released. For more information, visit Microsoft Baseline Security Analyzer.

Windows Server Update Services

By using Windows Server Update Services (WSUS), administrators can quickly and reliably deploy the latest critical updates and security updates for Windows 2000 operating systems and later, Office XP and later, Exchange Server 2003, and SQL Server 2000 to Windows 2000 and later operating systems.

For more information about how to deploy this security update using Windows Server Update Services, visit Windows Server Update Services.

Systems Management Server

Microsoft Systems Management Server (SMS) delivers a highly-configurable enterprise solution for managing updates. By using SMS, administrators can identify Windows-based systems that require security updates and to perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users. For more information about how administrators can use SMS 2003 to deploy security updates, see SMS 2003 Security Patch Management. SMS 2.0 users can also use the Software Updates Services Feature Pack to help deploy security updates. For information about SMS, visit Microsoft Systems Management Server.

Note SMS uses the Microsoft Baseline Security Analyzer and the Microsoft Office Detection Tool to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of the SMS in these cases to target updates to specific systems. For more information about this procedure, see Deploying Software Updates Using the SMS Software Distribution Feature. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2003 Administration Feature Pack and in the SMS 2.0 Administration Feature Pack) to install these updates.
