This post is for those who've been doing some network security and want to make it official and get the CISSP certification.
ISC2 has a set of intro videos to get you started. They are about 15 minutes each. The first is an introduction and then there is one for each of the 10 domains. This is not a course on becoming a CISSP, just an introduction to the type of information you would need to be familiar with.
If you are at that point of your career that moving firmly into the domain of security is appealing to you, this is a nice little preview of what's ahead of you.
