If you didn't make it to SharePoint Connections 2008 this year, we have a little taste of what you're missing. Currently showing on the ITTV.com video site is a roundtable discussion of SharePoint security. Listen to SharePoint gurus Michael Noel, Kevin Laahs, and Dan Holme, all presenters at the show, give a high-level overview of the different aspects of securing your information assets within SharePoint. Learn about topics such as Rights Management Services (RMS), authentication, and authorization and how they relate to SharePoint security. And get the low down on how ISA Server and IAG can help protect your Internet-facing SharePoint sites. Good stuff here. Scroll down to see the video, or go to ittv.net.
