When I picked up this book I was hoping for a 21 day romp into the world of CISSP. This is not the case. What CISSP in 21 Days is however is pretty awesome.
To become a CISSP you have to have 5 years experience in one of the 10 domains, pass a 100 question test about the 10 domains of being a CISSP, and adhere to a code of ethics set forth by the ISC2.
Now if you have the above requirements licked, then you are going to need CISSP in 21 Days. This is the best review book I have seen for this certification, and it is an easy read.
Author M. L. Srinivasan, CISSP, takes you day by day for 21 days reviewing all the domains of the CISSP. He covers Access Control, Application Security and more.
Be warned this book will not get your ready for your CISSP test if you don't already have the knowledge, this is just a primer!
With that said, I can suggest to anyone thinking of becoming a CISSP, like me, to get this book and read it. Then go back through the book and review each section outside of the book as well. Read about application security and then go and get the required knowledge under you belt. The book will act as an outline for what you need to know to pass the CISSP.
