Anyone who deals with computer and network security in their jobs owes it to themselves to check these two security resources now and then. Microsoft's security-related webcasts have been broken down into slightly smaller (it's all relative - 45 minutes is shorter than 2 hours ) chunks. You can check out archived presentations as well as sign up for live session to be held in the near future.

• Upcoming Live Security Webcasts
• On-Demand (Archived) Security Webcasts

In my experience. these are quality webcasts with actual useful information - A great resource for learning as well as staying on top of things. Webcasts provide a forum for addressing things in a fashion that's a lot like the real-world, so the practical use of the information is often better than that from other means of communication. If you happen to catch any of the live webcasts, there is typically a chance to ask questions during the session - so take advantage where needed.
