These installation instructions are for the Microsoft Baseline Security Analyzer version 2.3

There are two different types of MBSA tools available and the one you will install will be dependent on the type of workstation you are installing the tool on. There is a 64-bit version and a 32-bit version of the MBSA tool.

The 64-bit version can be downloaded from the following URL:

https://admin.certna.org/Downloads/MBSA23x64.zip

The 32-bit version can be downloaded from the following URL:

https://admin.certna.org/Downloads/MBSA23x86.zip

This zip files are approximately 1.3 MB in size.

Important Note: If you currently have another version of the Microsoft Baseline Security Analyzer installed, you should uninstall the older version, before installing an updated version of the software.

Important: Microsoft has ended support for the MBSA tool, which is why CeRTNA has the software available for download directly from our website. In the future, CeRTNA plans to replace the MBSA tool with another security analyzer, but until further notice, we will continue to use Microsoft Baseline Security Analyzer version 2.3 for our security scanning/reporting needs.

Unzip either the MBSA23x64.zip or the MBSA23x86.zip file to a working directory, for example C:\MBSA_Setup or a name of your choosing.
