<p>This article in our <a href="/b/security/archive/2012/07/31/microsoft-s-free-security-tools-series-introduction.aspx">series</a> on Microsoft’s free security tools is focused on a tool called the <a href="http://approjects.co.za/?big=en-us/download/details.aspx?id=7558">Microsoft Baseline Security Analyzer</a> (MBSA). Many years ago before Windows Update was available, servicing software was much more painful than it is today. Microsoft released security updates weekly, and there were few deployment technologies available to help determine which systems needed which updates. I wrote an <a href="/b/security/archive/2012/03/26/trustworthy-computing-learning-about-threats-for-over-10-years-part-6.aspx">article on this topic</a> if you are interested in a walk down memory lane. For those IT administrators that lived through those days, the MBSA was a godsend. Today, 10 years later, the MBSA is still a free security tool that many, many IT Professionals use to help manage the security of their environments. </p>
