The number of CISSP prep books has gone from zero two years ago, to about 15 in March 2003. With that, choosing the best CISSP prep guide is both a matter of personal preference, and budget; as some of these titles can cost nearly $90.00
While not cheap, ... the `CISSP Training Guide' by Roberta Bragg is definitely an excellent resource for anyone preparing for the CISSP examination.
This book, like all of the other CISSP prep guides is organized according to the 10 domains of the CBK (Common Body of Knowledge).
Where this book shines is in its organization and presentation of the material. The material itself is presented in a well-organized and easily readable style. Other titles are written in a much more technical style, which make memorization of the concepts more difficult. But Roberta Bragg has written her `CISSP Training Guide' in a very readable and clear manner.
The book also has a number of case studies that attempt to make the material more understandable by presenting real-world scenarios. The case studies do a fine job of taking often-abstract security concepts and mapping them into understandable ideas.
The CD-ROM is helpful, but there are many pop-ups requesting the test taker to pay to upgrade to a premium edition of the test.
Overall, the `CISSP Training Guide' is one of the better CISSP prep guides. Anyone looking for a solid CISSP preparation resource should definitely consider this book.
