I'm not sure if you're aware of these, but Ron Gula of Tenable Security is conducting a series of Webinars on a variety of interesting network security topics. I watched Tuesday's edition on vulnerability management.
The Webinars are not a selling vehicle for Tenable products. Instead, Ron explains one or more aspects of the security scene. If you know Ron you recognize he knows network security better than almost anyone out there. The next Webinar is scheduled for today, and all are free.
