The Windows Vista Blog pointed out a new report by Jeff Jones (a Microsoft Director from the Trustworthy Computing group). The conclusion? Vista is still faring better than other OSs, even though it’s under a larger microscope.

Jeff initially released his Windows Vista – 90 Day Vulnerability Report which looked at Vista’s vulnerabilities, and compared them to Windows XP, Mac OS X, Ubuntu, Novell SLED, and RHEL4LWS at their 90-day point. He’s now doing the same at the 180-day point, comparing against the same OSs. His conclusion is:

…Windows Vista continues to show a trend of fewer total and fewer High severity vulnerabilities at the 6 month mark compared to its predecessor product Windows XP (which did not benefit from the SDL) and compared to other modern competitive workstation OSes (which also did not benefit from an SDL-like process).

Considering that Vista is arguably the most scrutinized OS ever created, that’s doing pretty well. Seems that some of those practices that Microsoft put into place are working!
