Jones' analysis came in response to users' comments about a similar report he published in January that trumpeted Vista's security status on its first anniversary, he said. "In the wake of my Windows Vista One Year Vulnerability Report, which compared the 'first year of availability' of several products,You are not allowed to view links.

Computerworld - Microsoft Corp. touted Windows Vista's lower patch count yesterday, saying it required about 20% fewer fixes in 2007 than the four-year-old Windows XP Service Pack 2.
In the January report,You are not allowed to view links. Register or Login, Jones had compared Vista with the original version of XP, and called out statistics that said Vista had posted about half as many vulnerabilities in its first full year of availability as Windows XP did in its opening 12 months.
Microsoft also patched fewer flaws marked "critical" and "important" -- the top two rankings in its four-level vulnerability scoring system -- in Vista (36 total) than in XP SP2 (50 total). By Microsoft's numbers, the company quashed 28% fewer critical or important bugs last year in Vista than in XP SP2.
Even as Jones touted Vista, he downplayed the significance of the vulnerability statistics. "This is not an analysis of 'the security' of these operating systems," he said, acknowledging that just one factor -- in this case the patch count -- "can't measure the absolute 'security' of an OS.
"[But] all other things being equal, is it easier to mediate risk on a system that has 10 vulnerabilities in a year or one that has 100 vulnerabilities in a year?" Jones asked rhetorically. "Which has a more negative impact on your security team and risk management process -- deploying 10 security updates per year or deploying 100 security updates per year?"
At the time, some users griped that the comparison was unfair because 2004's XP SP2 was the edition most commonly deployed,You are not allowed to view links.

Jeff Jones, a security strategy director in the company's trustworthy computing group who regularly cites vulnerability statistics, said that Microsoft plugged 45 holes in Vista during 2007 compared to 56 in Windows XP Service Pack 2 (SP2), the version of the aging operating system that was supplanted by SP3 only last week.
