A 2021 survey reveals that Windows has a 40% decrease in the number of security vulnerabilities compared to five years ago.

BeyondTrust reports the Microsoft Product Image Security Survey, indicating that by 2021, the proportion of vulnerabilities in all Microsoft software. has decreased by more than 5% Compared to the past 5 years, at that time, there was a continual increase in trend.

As of 2021, a total of 1,212 new vulnerabilities were discovered, one of which was ‘critical’ by CVSS standards. This year, it’s down 47% from last year, a steady decline every year and the lowest number in nine years since BeyondTrust conducted a survey.

If the focus is only on the security overview on Windows and Windows Server, it is found that both the number of vulnerabilities has decreased to 40% and 50% Respectively, the number of vulnerabilities in Internet Explorer and Microsoft Edge browsers increased to an all-time high. Which is not surprising as IE is very old software and Edge is still the newest browser since the engine switched to Chromium instead.

The survey said that the more recent vulnerabilities seen in 2021 are more frequent, often in which hackers try to gain access to information such as admin privileges. By 2021, this represents 588 of the total number of vulnerabilities ever seen.

Followed by 326 vulnerabilities related to remote code embedding and execution, followed by 66 Microsoft Office key hacking vulnerabilities and 44 Azure/Dynamics 365 vulnerabilities, which looked alike. It’s still a high risk, but the CSO insists it’s a very significant drop compared to the past.
