Many of the CIOs and CISOs that I talk to, have, over time, developed mature vulnerability assessment methodologies and security updating processes. But frequently, I find that the focus of these processes is squarely on keeping Microsoft operating systems and browsers up to date. Of course vulnerabilities in popular operating systems or browsers have the potential to affect a broad audience. Another reason for this focus is that Microsoft has made updating relatively easy by offering updates via Windows Update, Microsoft Update, and via various tools like Windows Server Update Services and others.
But data from our latest Security Intelligence Report suggests that customers need to keep all of their software up-to-date, not just Microsoft software.
In the last half of 2015 there were nearly 3,300 vulnerability disclosures across the industry, of which 305 were in Microsoft products. With more than 90 percent of reported vulnerabilities occurring outside the Microsoft portfolio, organizations need to monitor their entire technology stack to minimize their risk.
Microsoft products accounted for less than 10 percent of industrywide vulnerabilities in the second half of 2015.
This is consistent with previous years as well. The software industry worldwide includes thousands of vendors, and historically, vulnerabilities for Microsoft software have accounted for between three and ten percent of disclosures in any six-month period.
To find out what’s happening in the world of software vulnerabilities across your IT environment, take some time to review our latest Security Intelligence Report and the information available through the National Vulnerability Database (NVD), the U.S. government’s repository of standards-based vulnerability management data. And for a high-level look at the top ten trends and stats that matter most to security professionals right now, be sure and download our 2016 Trends in Cybersecurity e-book.
