Symantec's 11th Internet Security Threat Report has found that when it comes to widely-used operating systems, Microsoft is doing better overall than its leading commercial competitors. The report covered a huge range of security and vulnerability issues over the last six months of 2006, including operating systems and found that Microsoft Windows had the fewest number of patches and the shortest average patch development time of the five operating systems it monitored in the last six months of 2006. On average Microsoft took an average of 21 days to fix vulnerabilities. Red Hat came in second requiring an average of 58 days.
