CISSP Certification All-in-One Exam Guide, Fourth Edition (Cissp All-In-One Exam Guide) ReviewNot sure why this book is so highly rated. Having taken (and passed) the CISSP several years ago, I need to retake this exam and bought three books for review and study purposes. I have a previous version of the Harris book and it is ~900 pages. This new version is 1100+ pages, but seems to be filled more with fluff and some of the actually useful knowledge has been removed! One example which stands out is the removal of the effectiveness and acceptance charts for biometrics methods. This is an important concept and it is entirely ignored in this version. Other things have been changed to no real benefit. The CIA triad (as is the de-facto acronym, even in her previous book) has been renamed to the ICA triad. There is no reason for this.
Finally, the entire book is written in a dumbed-down, cutesy fashion in an attempt (I believe) to make the book more approachable. All it has done, IMO, has increased the number of pages, possibly forcing out relevant materials.
I will pass this test, but it won't be because of this book. Buy the ISC book and the Krutz book (and/or a previous version of the Harris book) - you will not be disappointed.
UPDATE: ok, took the test in Sept and passed. I won't turn this into a test review as this is about the book, but when you buy a certification book, your primary requirement is that the book will be timely and relevant to the test material. The 4th Edition Harris book does just that. ISC has made significant changes to both the content and nature of the test (in large part to keep its test current on security trends and to satisfy a larger target audience) and Shon has captured those changes very well. So, having said all that, it is my revised opinion that this book is more than adequate for passing the test (although it is still filled with fluff.) If I could change the review, I would probably give it 4 stars at this point. The ISC book and the Krutz book are both excellent references to actually apply the knowledge in a meaningful way, however if you just want to pass the test, the Harris book will serve you well.CISSP Certification All-in-One Exam Guide, Fourth Edition (Cissp All-In-One Exam Guide) Overview

Elementary Cryptanalysis 2nd edition (Anneli Lax New Mathematical Library) ReviewThis book would be an excellent text for courses in cryptology where some of the students are in computer science. The mathematics behind the encryption/decryption is completely explained at a level where people with a weaker mathematical background can understand it. Basic number theory concepts such as congruences, simple linear algebra and frequency statistics are all the mathematics that is needed. The coverage is introductory, yet the reader is given a sufficiently deep exposure so that they can appreciate the significance and value of encryption in the modern world. The worked examples also impart the sense of intellectual challenge and stimulation that working in encryption can give.
The areas examined are:
*) Monoalphabetic ciphers using additive alphabets
*) General monoalphabetic substitution
*) Polyalphabetic substitution
*) Polygraphic systems
*) Transposition
*) RSA encryption
*) Perfect security - one-time pads
Many exercises with solutions are also included, which would allow a reader to use the book for self study as well.
Of all the areas of mathematics that I have taught, I had the most fun teaching a course in encryption and compression. Furthermore, given the feedback that I received from the students, they enjoyed it as well. This is one of the very best books on the basic tactics of encryption that has ever been published; I would not hesitate to use it as a text.
Published in Journal of Recreational Mathematics, reprinted with permission.Elementary Cryptanalysis 2nd edition (Anneli Lax New Mathematical Library) OverviewOriginally published in the New Mathematical Library almost half a century ago, this charming book explains how to solve cryptograms based on elementary mathematical principles, starting with the Caesar cipher and building up to progressively more sophisticated substitution methods. Todd Feil has updated the book for the technological age by adding two new chapters covering RSA public-key cryptography, one-time pads, and pseudo-random-number generators.Exercises are given throughout the text that will help the reader understand the concepts and practice the techniques presented. Software to ease the drudgery of making the necessary calculations is made available. The book assumes minimal mathematical prerequisites and therefore explains from scratch such concepts as summation notation, matrix multiplication, and modular arithmetic. Even the mathematically sophisticated reader, however, will find some of the exercises challenging. (Answers to the exercises appear in an appendix.)

CISSP All-in-One Exam Guide, Fifth Edition ReviewThere is no simple formula to prepare for the CISSP certification, and no single resource which can guarantee success on the certification exam since every applicant's background is unique. However, this book (fifth edition) was my only resource in preparing for the exam and I passed on my first attempt (April 24, 2010).
I spent 60+ hours in preparation for the exam... that's 60+ hours of DEDICATED individual study using this book and CD, not 60+ hours spent web surfing during lunch hours or commercial breaks. My recent background is in middle management, with 20 years experience in network architecture and data security, so I already had a firm technical foundation for the test areas dealing with protocols and encryption variations. I also have an MS in Computer Science. Nonetheless, the exam was so broad, with topics covering general principles and concepts, that I could have prepared twice as long and still left the exam with questions about the outcome.
My personal opinion is that formal classroom instruction, through one of the many organizations offering CISSP preparation courses, is a worthwhile companion to Shon Harris' book. A study group is also a good idea. You will not obtain CISSP certification if you take the exam without preparation. This book (fifth edition) was sufficient, but not 100% comprehensive, to prepare me for passing the CISSP test.
Note: Some reviewers do not appreciate Shon's frequent analogies and humor. Most of her analogies helped me internalize the complex topics, but that's my personal learning style. The efforts at humor were generally awful, but every once in a while she was subtle and brilliant enough to make me laugh out loud. Working through Shon's unique writing style was not a problem for me... I actually found it refreshing.CISSP All-in-One Exam Guide, Fifth Edition OverviewGet complete coverage of the latest release of the Certified Information Systems Security Professional (CISSP) exam inside this comprehensive, fully updated resource.
