Microsoft: We patch faster than Apple, Novell, Red Hat

Windows users were at risk for in-the-wild vulnerabilities fewer days on average last year than users of rival operating systems from Apple, Novell, Red Hat and Sun, a Microsoft executive claimed.

Jeff Jones, strategy director in Microsoft's security technology unit, has posted findings that show Microsoft released patches for vulnerabilities in Windows overall -- and Windows XP in particular -- faster than its four competitors did for flaws in their software. A Symantec executive acknowledged that Jones' data "reads accurate."

In two entries on his CSO blog, Jones laid out his analysis of "days-of-risk," a term that describes the time from when a vulnerability is announced or goes public, to when the vendor releases a fix. By Jones' calculations, Windows -- including 2000, XP and Server 2003 -- boasted an average days-of-risk (or DoR) last year of just under 29 days, compared to Mac OS X's 46 days, SuSE Linux Enterprise's 74, Red Hat Enterprise Linux's 107, and Sun Solaris' whopping 168.

That puts Microsoft 159% faster than Apple in preparing and distributing patches, 255% faster than Novell, and 579% faster than Sun.

When Jones focused on specific operating system clients -- Windows XP SP2, Mac OS X 10.4, Red Hat Enterprise Linux 4 Workstation, and SuSE Linux Enterprise Desktop 9 -- Microsoft still took first place, although the race was tighter. Windows XP was patched after an average of 53.3 DoR, just 1.6% faster than Apple's Tiger at 54.2 DoR. SuSE and Red Hat came in third and fourth, with 56.2 and 70.5 DoR respectively.

Alfred Huger, vice president of engineering with Symantec's security response group, said that Jones' numbers look reasonable. "Our latest ISTRs (Internet Security Threat Reports) had more or less the same." In its most recent report, Symantec's reckoning pegged Windows' average DoR for the last six months of 2006 at 21 days, Red Hat's at 58, Mac OS X's at 66, and Sun's at 122.

"We don't disagree, certainly [on the numbers]" said Huger. "[Jones'] reads accurate."
