The world's most business-critical transactions run on Unix machines, which means the machines running those transactions attract evildoers. Furthermore, a lot of those machines have Internet connections, which means it's always possible that some nefarious remote user will find a way in. The third edition of Practical Unix & Internet Security contains--to an even greater extent than its favorably reputed ancestors--an enormous amount of accumulated wisdom about how to protect Internet-connected Unix machines from intrusion and other forms of attack. This book is fat with practical advice on specific defensive measures (to defeat known attacks) and generally wise policies (to head off as-yet-undiscovered ones).
The authors' approach to Unix security is holistic and clever; they devote as much space to security philosophy as to advice about closing TCP ports and disabling unnecessary services. They also recognize that lots of Unix machines are development platforms, and make many recommendations to consider as you design software. It's rare that you read a page in this carefully compiled book that does not impart some obscure nugget of knowledge, or remind you to implement some important policy. Plus, the authors have a style that reminds their readers that computing is supposed to be about intellectual exercise and fun, an attitude that's absent from too much of the information technology industry lately. Read this book if you use any flavor of Unix in any mission-critical situation. --David Wall

Customer Review: Excellent Guide
This book is just what I was looking for. Excellent Security Guide to day to day security issues at my workplace. Information about TPC and UDP ports and their security risks have been very useful.
This book must be part of every UNIX System Security Profesional.
Customer Review: Order a wrong edition
I saw that there is a bargain of another paperback edition on the page of 3rd edition, so I didn't recheck whether it is 3rd edition. So I end up in buying 2 books, 2nd and 3rd editions, because I need the 3rd edition for my class. It would be better to put edition number up in the page, not only paperback or library binding!
