Very nice. This book covers various interconnected internet security issues including email forensics, the inner workings of SMTP, spam, phishing, hacked spam-bot servers, proxy servers, anonymous surfing, and DNS. This is a relatively easy read considering the topics and the book is generally written in such a way as to tie all the topics together into a cohesive analysis. This was helpful since real-world situation never involve only one of these technologies but instead require a progression. The book discusses both theory and practical application.

I found the information helpful and would like to see the next edition cover each topic with more depth. Also I would like to see more variation of the email topics. For example, a section on Outlook/Exchange specific emails, IMAP protocol emails, etc. could be useful. There were some sections that would benefit from more examples as well. For instance, a section on how to dissect Microsoft Outlook formatted emails using Cygwin or Linux would have been a nice edition.

I definitely recommend it and enjoyed studying the contents.

Summary:

- Very good advice for both professional in the computer security field, hobbyist, and those concerned with personal computer security.
- Focus is on practical advice and examples
