When I took the SANS long course a few months ago online, they provided several books of course, but I found them all hard to digest. Are there any additional resources out there, a bit more condensed, that could help me understand the concepts I need to learn? I've looked on Amazon for resources but oddly, all of the books on the GSEC exam and how to study are quite outdated.
What about the Network Security Bible? That one at least had good reviews.
Oh, why oh why can't someone create an Exam Cram for this cert?

I'm finding it invaluable for studying for the A+ along with the Messer videos.
I just received my 60-day warning that I have to schedule my exam so I have to get cracking on that as soon as I get A+ under my belt in a few weeks. Ugh...
