Security Engineering: A Guide to Building Dependable Distributed Systems ReviewFor the typical busy security professional, reading a 900-page tome cover to cover represents an investment of time that may be difficult to justify. Frankly, security books that are worth the effort are few and far between. Security Engineering is one such book, for several reasons.
First, Ross Anderson's vast knowledge, experience and insight on the subject are well known, and his reputation as one of the top security experts in the world is well deserved. No doubt a reflection of this, his book covers a very broad range of security topics, the discussions ranging from high-level policy issues, all the way down to details of smartcard hacking and the mathematics of cryptography. The topics are well researched and described at a level of detail useful to the non-specialist. Concise summaries and occasional nuggets of insight indicate an in-depth understanding of the subject matter. The book is well written, easy to follow, and devoid of the vagueness and platitudes so typical of much of the security literature.
Second, the book exposes the sheer difficulty of engineering secure systems in the face of the many forces at play in a typical product development lifecycle. Through many case studies of success and failure, the author illustrates the numerous pitfalls that may befall even a well-intentioned design. Lessons learned from deploying products in the real world include the negative impact of perverse economic incentives, the importance of designing security features for maximum usability, and the need to look at a security problem from many different angles in a holistic manner. The book is a treasure trove of wisdom for the aspiring security engineer.
Lastly, the book brings together insight from many diverse areas of research. Disciplines ranging from economics, psychology, sociology, criminology, banking and bookkeeping, safety research, electronic warfare, to politics are all mined for ideas and results that could yield a better understanding of - and novel approaches to - difficult security problems. It is perhaps in this aspect that the book will prove to be most influential. Since the first edition was published in 2001, security economics, security usability, and security psychology have emerged as fertile areas of research.
Security Engineering: A Guide to Building Dependable Distributed Systems OverviewThe world has changed radically since the first edition of this book was published in 2001. Spammers, virus writers, phishermen, money launderers, and spies now trade busily with each other in a lively online criminal economy and as they specialize, they get better. In this indispensable, fully updated guide, Ross Anderson reveals how to build systems that stay dependable whether faced with error or malice. Here?s straight talk on critical topics such as technical engineering basics, types of attack, specialized protection mechanisms, security psychology, policy, and more.

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.
