I have had the CISSP certification squarely on my radar for about a year now, but the sheer amount of information to compile and read and remember is simply too much. This is because the compiled readings are mainly at best, guesswork. What's more, the weightages of the Ten Domains of Computer Security can be markedly different, and no one can really be sure of the importance of certain sections as compared to others. For example, both authors who are themselves CISSP certified, place Telecommunications and Network Security as more heavily covered in the exam than say, Security Management Practices, clearly a time saver for those who like me, am also pursuing the BS7799 Auditor certification.
Within each chapter, the authors also clearly prioritize the topics. In the Chapter entitled Access Systems, the topic Decntralized/Distributed Access Control takes up half of the chapter, again, demonstrating that more attention has to be paid by the reader.
Though the information to cover is vast, I never felt that I needed a map to navigate the contents. Each chapter's objectives are clearly stated, and the section lucidly explained. Best of all, the visual and textual aspects are just right for the eye. Of course, for a exam that covers 10 domains, the number of acronyms faced is numerous, but the nifty Glossary takes care of any confusion that may arise. Besides the coverage of the ten domains in 10 chapters, the Appendices are extremely helpful. Topics such as HIPAA Compliance through HIPAA-CMM are covered, so is the British Standard 7799.
If you feel that coverage is not deep enough (which is not really a factor in the exam), the authors provide useful References for Further Study, also found as Appendix H.
In summation, the book is extremely well organized, and the additional information provided in each Appendix make this not only a required study tool, but also a "must have" reference.
