Query: Not for Beginners

Cox & Sheldon take a lot for granted - Their book is great if you're studying for the MCSE or have any kind of networking background but if you're new to group policy, domains and OUs and the like, then it's likely going to be a struggle to read. I gave the book 5 stars because eventually, through hands on, self-taught trial & error on my own system, I was able to master some of the basic security concepts. If you're a lazy n00b and you don't have any kind of initiative or a mentor, then don't waste your time or money with the book.
