Jeff Jones, a security strategy director in Microsoft’s Trustworthy Computing group, reported that Windows Vista is more secure OS than XP since it was hit by significantly fewer publicly disclosed security flaws in its first year than Windows XP and open source rivals in their first years. In its first year Microsoft released 17 security bulletins and patches affecting Vista, compared to 30 for XP in its first year. Vista had 9 patches, XP had 26, Red Hat 64, Ubuntu had 65 and Mac OS X 17. Most of those success is related to the changes made in way Microsoft handles patching and that resulted in less work for system administrators on Vista compared to Windows XP. However those figures do not indicate which operating system is “more secure” than the others.
