I thoroughly enjoyed Winn Schwartau's book. He gives the reader an insightful look of hackers and phreakers community. He doesn't berate that community, but helps the reader understand what they are about. Schwartau's book makes this dangerous issue easy to understand and is written in a way that everyone has a chance of reading this book. He also fills the book with examples of security breaks that he has encountered. His stories seem scary at first, but he also emphasizes that there are ways to deter such attacks. His idea is not to get readers to stop using computers and the Internet because of such attacks, but to get them aware of what it out there and to take countermeasures. His real life stories are what make the book interesting to read and enjoy. I think that he could have offered sort of program that would allow the reader to see an example of a security program, maybe negotiating a deal to market a program would have been nice to include.
