macro settings. Security updates are determined by the current version of MBSA using the Windows Update Agent present on Windows computers since Windows 2000 Service Pack 3. The less-secure settings, often called Vulnerability Assessment (VA) checks, are assessed based on a hard-coded set of registry and file checks. An example of a VA might be that permissions for one of the directories in the wwwroot folder of IIS could be set at too low a level, allowing unwanted modification of files from outsiders.
Versions 1.2.1 and below run on NT4, Windows 2000, Windows XP, and Windows Server 2003, provide support for IIS versions 5 through 6, SQL Server 7 and 2000, Internet Explorer
5.01 and 6.0 only, and Microsoft Office 2000 through 2003. Security update assessment is provided by an integrated version of Shavlik's HFNetChk 3.8 scan tool. MBSA 1.2.1 was localized into English, German, French and Japanese versions and supported security assessment for any locale.
Version 2.0 retained the hard-coded VA checks, but replaced the Shavlik security assessment engine with Microsoft Update technologies which adds dynamic support for all Microsoft products supported by Microsoft Update
. MBSA 2.0.1 was released to support the revised Windows Update (WU) offline scan file (WSUSSCN2.CAB). MBSA 2.1 added Vista and Windows Server 2008 support, a new Vista-styled GUI interface, support for the latest Windows Update Agent (3.0), a new Remote Directory (/rd) feature and extended the VA checks to x64 platforms.
