Linux riskier than Windows?

Companies face greater risks if they run their Web sites on Linux rather than Windows, a Microsoft-funded study has concluded.

Last year, Web servers based on Windows Server 2003 had fewer flaws to fix than those based on Red Hat Enterprise Linux ES 3 in a standard open-source configuration, researchers said in a paper released on Tuesday.

Moreover, the study indicated that the Microsoft-based Web server had far fewer "days of risk"--a measure of the number of days that each vulnerability is known, but unpatched--than the open-source rival.
