Wireshark Network Analysis (WNA) is a very practical, thorough, comprehensive introduction to Wireshark, written in an engaging style and produced in a professional manner. WNA provides a variety of methods for teaching network analysis with Wireshark, including description, screen shots, user-supplied case studies, review questions (with answers), "practice what you've learned" sections, and dozens of network traces (available online). Readers who approach the book as more of a class in printed (text) and electronic (trace file) forms will likely understand the higher-than-normal price tag. Anyone trying to learn how to use Wireshark, including basic protocol analysis, will greatly benefit by reading WNA.
WNA will not bore you. Author Laura Chappell offers one of the more lively writing styles you're likely to find in technical books, reminiscent of Michael W. Lucas. The book is expertly organized, starting with multiple chapters explaining Wireshark, followed by sections on common protocols and concluding with other uses and applications. WNA provides plenty of coverage on configuration, customization, and profiles which I have not seen addressed elsewhere.
I've been using Wireshark (previously Ethereal) for at least 10 years, and I still found a few cool tips by reading WNA. These included right click -> Apply As Column, right click -> Filter Field Reference, right click -> Colorize Conversation, Display Filter auto-completion, Display Filter Macros, Mark Packet with ctrl-M, and Ignore Packet with ctrl-X. I also learned that applying a display filter to Tshark (via -R) does NOT change the packets saved to disk -- only those counted or displayed on screen. I liked the chapters on WLAN and VoIP analysis, 26 and 27 respectively.
I only have a few caveats for WNA. First, the book doesn't talk about how to extend Wireshark. It doesn't explain how protocol dissectors work, or how to use the Lua programming language with Wireshark. The chapter on network forensics (ch 30) doesn't saw much about the subject. I would have liked examples of using Rawshark in chapter 33.
I also appreciate that WNA offers an online errata so readers can identify any typos. For example, I expect to see an issue I found with Figure 200 on p 378 to appear soon; basically some of the TCP sequence numbers need to be adjusted. Also on p 452, "Referrer" should be the misspelled but accurate Referer.
I have recommended all my junior analysts read WNA. They will learn a ton about Wireshark, and will also be able to follow Laura's explanations of many common network protocols. We may even pursue the certification tied to the book. Great work Laura!
