Comparing security on Windows and Linux

Comparing security on Windows and Linux: "Recent U.S. Computer Emergency Readiness Team (CERT) vulnerability metrics reported 250 episodes for Microsoft Windows, 39 of these having a severity rating of 40 or greater. With Red Hat Linux there were only 46 episodes, of which only with only 3 scored over 40. There are thousands of reports that compare the two operating systems but reports like this by an independent government body, on the relative number of critical flaws between them, should be given greatest consideration."
