There have been six vulnerabilities deemed "important" or "critical" for Windows Server 2003 since its release last April against 21 vulnerabilities in the same period of time after the Windows 2000 Server release, according to Nash.
Hmmm.... I'd suggest that a 72% decrease in vulnerabilities shows a distinct improvement on M$'s part to fix their ailing security reputation. The naysayers will probably refute that but if there were a 72% decrease in crime in their neighborhood they would be voting the local leader back into power I'm sure.
