The CISSP Exams are meant to certify interested individuals in the CISSP form of accreditation. Passing this IT accreditation allows the candidate to eventually be granted the status of Certified Information Systems Security Professional (or CISSP.) This means having to undergo the appropriate training, which in turn means having to purchase CISSP textbooks so you can learn what the CISSP exams cover.
So where can you buy your CISSP examination textbooks then?
You can try buying one reputable book for the CISSP exams (entitled The CISSP Prep Guide: Mastering the CISSP and ISSEP Exam, Second Edition) from either the well-known Amazon.com site, or the not-so-well-known www.bigwords.com site. This book was written by co-authors Ronald L. Krutz and Russell Dean Vines. Amazon.com highly recommends this book for both future candidates for CISSP accreditation and practicing professionals in the realm of Information Systems Security. Both authors Krutz and Vines are very competent at explaining even very complex topics in a way that does not alienate even the newbies to CISSP accreditation.
Amazon.com and previous users of The CISSP Prep Guide recommend as well that you use other books about the CISSP exams and their coverage to supplement this book.
If you need such complementary books, head for Barnes and Noble and inquire online about the book entitled: CISSP Certification All-In-One Exam Guide, Third Edition (authored by Shon Harris.) If you find the original price tag of $63.99 a bit steep, it is possible that used copies of the same book are available for a much lower price (being second-hand.) Like the CISSP Prep Guide, it provides information not just about CISSP but also about the other form of IT accreditation called ISSEP.
