| "Vista has an improved security vulnerability profile over its predecessor, and a significantly better profile relative to comparable modern competitive operating systems," Jones asserted in his blog. By his count, Vista has been hit by just one vulnerability since its introduction to enterprises at the end of November. The bug, which was in the anti-malware scanning engine used by the bundled-with-Vista Windows Defender, was patched last month. By comparison, said Jones, in their first 90 days, Windows XP was nailed with 14 bugs, Mac OS X 10.4 (Tiger) with 20, Red Hat with 137, Ubuntu with 71, and SuSE with 80. Even when vulnerabilities that were disclosed but not patched are added in, Vista still comes out far ahead. Its five total bugs -- one patched, four made public but not fixed as of Feb. 28 -- compared favorably with XP's total of 18, Mac OS X's 27, Red Hat's 201, Ubuntu's 100, and SuSE's 111. |
