Microsoft Baseline Security Analyzer

Microsoft Baseline Security Analyzer (MBSA) lets administrators scan local and remote systems for missing security updates as well as common security misconfigurations. MBSA includes a graphical and command line interface that can perform local or remote scans of Microsoft Windows systems.

MBSA 2.3 builds on the previous MBSA 2.2 version that supports Windows 8.1, Windows 8, Windows Server 2012 R2, and Windows Server 2012 and corrects minor issues reported by customers. More information on the capabilities of MBSA is available on the MBSA Web site

MBSA 2.3 runs on Windows 8.1, Windows Server 2012, and Windows Server 2012 R2, Windows Server 2008 R2, Windows 7, Windows Server 2008, Windows Vista, Windows Server 2003 and Windows XP systems and will scan for missing security updates, rollups and service packs using Microsoft Update technologies. To assess missing security updates, MBSA will only scan for missing security updates, update rollups and service packs available from Microsoft Update. MBSA will not scan or report missing non-security updates, tools or drivers.
