TechNet Learning Paths v1.00
The folk over in Microsoft IT Pro marketing have put together the TechNet Learning Paths site. The site is a rev1.00 to help folk find a range of Microsoft training references and resources on security threats and appropriate countermeasures.
The info is organized by level (from basic to expert) and provides information on the planning, prevention, detection, and response phases of security implementation.
Give it a look at http://www.microsoft.com/technet/security/learning/default.mspx and feel free to fire off comments, edits and ideas on it to me and I'll show your constructive ideas to the IT Pro marketing folk.
