Via Joe Mayo, Via Sam Gentile “Reported by CNET, of all the CERT security vulnerabilities of the year 2005, 218 belonged to the Windows OS.  But get this - there were 2,328 CERT security vulnerabilities for UNIX/Linux systems.”

My initial reaction to this was that it was apples to oranges, but after examining the original CERT bulletin, it seems to be a fair comparison. Both lists include vulnerabilities that are not in the core OS and both lists include multiple “distros” of the core OS (e.g., Win2000 & Win XP, Apple OS X & FreeBSD). While there are more UNIX/Linus distros than Windows distros, it’s also true that there are more Windows 3^rd-party apps, so I think that’s a wash.
