Reddit mentions of CompTIA Network+ Certification All-in-One Exam Guide, Seventh Edition (Exam N10-007)

If you've got a couple of weeks until your start date, buy this book and read it:

CompTIA Network+ Certification All-in-One Exam Guide, Seventh Edition

You can also look up the author's series of videos on Youtube. You don't actually have to take and pass the certification but it wouldn't be the end of the world if you did. Since you say you didn't have a single comp sci class it would actually probably help with your confidence to get certified and to understand the ins and out of networking. If you can break down how computers communicate with each other you can go a long ways towards figuring out potential security problems.

My guess is that their "analyst" training will be much more about NIST Special Publication 800-53 than any actual network or security analysis but that's fine. If you can learn some tech stuff on your own you won't look like a total n00b when they deposit you at a client site and tell you to add value immediately or else.
