I've started preparing for the CISSP exam. I'm planning to take it later this year and definitely after they update the test in April. No problem. I've downloaded the exam objectives and am using that as the basis for my study plan. I've compared the new objectives with the old and found there's not much difference. I'm using some free sources such as Cybrary and FedVTE, and I have access to the Eric Conrad book on Skillsoft (paid for by my agency). I would like to have yet another point of view, so I've started looking at the official guide. Many of the reviews state that this guide is crapola.
However, the Sybex book, written by Darril Gibson, et al, has glowing reviews. And honestly, if it's anywhere close to being as good as Gibson's Security+ book, I'm sold.
The only thing is that these guides were written for the 2015 test. I realize that not much will change. So, my question (finally!): Should I wait for the Sybex book to be updated or just buy the 2015 version?
