I am not suggesting that I agree with this data – to be honest, I haven’t had time to read the full report (warning – PDF) yet. But I will read it, and I thought some of you might find it interesting as well.
Vista came out in front: Vista had 5 vulnerabilities in its first 90 days, one of them fixed, and one pending with a High severity rating. By comparison, XP had a total of 17 vulnerabilities in its first 90 days, 8 of which were rated High, when it shipped in 2001. The surprises, however, come when you compare the non-Microsoft competition. Mac OS X 10.4, a darling of the press, actually suffered from 20 vulnerabilities in its first 90 days, 8 of which were rated High. Worse, OS X 10.4 still suffered from 17 publicly disclosed but unpatched vulnerabilities at the end of those 90 days. "The data doesn’t support [Apple’s] marketing," Jones writes. Linux fared even worse: Ubuntu 6.06 suffered from a whopping 71 vulnerabilities in its first 90 days, 27 of those rated High. And there were at least 29 unpatched vulnerabilities in that OS after the 90 day period ended.Source: Bink.nu | Microsoft: Windows Vista Safer than OS X, Linux
