The Certified Information Systems Security Professional (CISSP) rating is difficult to earn and rare in the marketplace, which means you"re a valuable commodity if you"ve proven your skills by passing the exam. The CISSP Prep Guide, one of only a handful of books on its subject, does a good job of giving readers a feel for the scope of the test and the style of its questions. It"s ideal for use either as a preliminary survey of the CISSP subject areas (the test"s publisher and the authors of this book call them "domains") for relative newcomers to computer security, or as a pure study guide to help more experienced professionals zero in on the weak spots in their knowledge. Don"t expect to do well on the CISSP exam having only read this book. You"ll want to have some practical experience and some specialized reading under your belt.Ronald Krutz and Russell Vines are good writers and fine teachers; they explain the wide-ranging CISSP domains (which have to do with everything from cryptographic algorithms to fire-suppression techniques to legal principles). They take care to explain potentially unfamiliar terms--there"s a good glossary in the back of this book--and employ conceptual diagrams well. However, the answer keys for the sample questions that conclude each chapter aren"t annotated and some readers will wish for more references to specialized sources. --David Wall Topics covered: The subjects covered by the Certified Information Systems Security Professional (CISSP) exam published by the International Information Systems Security Certification Consortium, including cryptography, access control, security policy, legal matters, and the physical safety of information, equipment, and people.
