The boys over at Activewin have done something Microsoft haven"t (and should really), they have gone and made a compilation of all the security bulletins released for 2002. Titled Microsoft Security Bulletin Summary List 2002 the list is complete with brief description, date and link to the Technical article on the Microsoft website.
Microsoft also unleashed a campaign in 2002 to better the companies stance towards the customer on security issues, before the release of Windows XP it was widely speculated that Microsoft needed to brush up on its security focus toward customers who just plain didn"t know where they could get their "fix" other than good ol Winnie Update.
With the release of the "Security Roll-up Package" Microsoft is on the correct path when it comes to offering tools for administrators to secure their environments. We wish Microsoft a better and more secure 2003 and from what we"ve seen this year with the first client based Service Pack for Windows (that actually got off the ground and meant something) I think MS are on track to achieving something on the Patch, Secure and Update initiative.
