Computer Security: Principles and Practice [Hardcover]

Stallings and Brown directs the book at a computer professional, who might be a programmer or system administrator. The book deliberately minimises the mathematical aspects. Much of the topic consists of layers above sophisticated encryption algorithms. Alas, a detailed treatment of the latter often requires heavy math background. If you do desire such a treatment, I recommend Matt Bishop's Introduction to Computer Security. That book was deprecated by some reviewers, who found it too mathematical.

Anyway, back to Stallings and Brown. It does proffer good technical explanations of various malware. Like worms and viruses. And attack modes like Denial of Service, and Distributed Denial of Service. Important variants are also covered - reflector and amplifier attacks.

Countermeasures to malware then naturally enter the narrative. So you learn how a firewall functions. Plus how to set up a honeypot to attract spam, phishing and malware.

So far, the above might be regarded as external attacks on your system. Sometimes, worms or viruses might try to take advantage of weaknesses in installed programs. Hence, another section of the book is for those of you who write such programs. Explaining how to guard against buffer and stack overflows, for example. These 2 are perhaps the most common entry points for malware.

The content is okay. I would prefer some more detail and less "fluff" that's been pulled from old papers about security. My main complaint about this book is the sheer number of misspellings and typos. For example, I've just read one section that says "see section E" for further detail. There isn't a section "E" -- contextually, you can determine quickly that they mean section "D". I feel like I'm reading someone's draft and not a final product.

Also, most modern books include either a self-testing CD or a web site where you can quiz yourself. If you're using this book for self-study (as opposed to being in a class), it's difficult to gauge how well you're retaining the information. This book does not include a CD. It does, however have a companion web site but I was unable to find a self-assessment tool on that website.

The author of this book also wrote the widely used text "Cryptography and Network Security". I like that book well enough, but you have to use outside resources to understand what's going on in that book, and I would say that is even more true for this textbook. That is because the author is basically taking subjects discussed in the Cryptography and Network Security book and adding topics like management issues and security of specific operating systems - without getting specific enough that you could actually solve too many problems. To me the best parts of the book are the appendices. The information on number theory is quite good, as are the suggestions for projects and labs. Unfortunately, this book does not contain sufficient information to perform those projects and labs. The contents make a good starting point for the study of computer security, but if you are an instructor be prepared to use lots of supplemental material or your students are going to be left high and dry. Currently the table of contents is not shown, so I include it next. This book is just under 900 pages long, so its 24 chapters are covering their subject matter in under 40 pages each, which does not give much room for detail.
