5.0 out of 5 stars Excellent book with material beyond Wireshark, April 9, 2010
This review is from: Wireshark Network Analysis: The Official Wireshark Certified Network Analyst Study Guide (Paperback)
I was a little nervous when I started reading this book. Chapter 1 provided an overview of network analysis, but had a lot of "personality." When I read, "Wait...more data is coming in...and more...and...SCREECH!" I wasn't too sure if I was going to finish the book. At over 700 pages, I was hoping that each page contained only "meat and potatoes," without a lot of dry humor and meaningless analogies. Thankfully, a few pages later I began what turned into a great read -- full of solid content.

Wireshark Network Analysis goes well beyond Wireshark functionality. Although the first several chapters outline how to best use Wireshark -- examining the settings, filters, and other configurations -- I think the true value of the book is in the detailed explanations of network traffic analysis. For instance, pg. 304 delves into DNS. This section tells the reader exactly what DNS is used for and provides an analysis of normal and abnormal DNS traffic. It also shows screenshots of the packet, displays and describes its contents. This type of analysis is provided throughout the book and covers all forms of network traffic (including suspect traffic -- my personal favorite).

Page 563 resonated with me, as I'm a firm believer in baselining network traffic. In this section, Wireshark Network Analysis details the importance of baselining and the types of traffic to focus on. Like other sections, this section also provides screenshots and shows how to analyze traffic and packet statistics.

There were minimal grammar errors, and it does seem like the case studies were not tech edited by the book editor -- many of them contained several grammar mistakes. Although, it does appear that the case studies were all submitted by third parties and probably used as-is. Nevertheless, I can provide plenty of other examples as to why Wireshark Network Analysis is a great book. There are plenty of screenshots, review questions with answers on the next page (instead of making the reader turn to the back of the book), and links to tons of packet captures for analyzing on your own. Overall, the book is well-written and, in my opinion, the best network analysis book on the market today.

5.0 out of 5 stars Best introductory book on Wireshark available today, August 5, 2010
This review is from: Wireshark Network Analysis: The Official Wireshark Certified Network Analyst Study Guide (Paperback)
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!

5.0 out of 5 stars Hands down the best network analysis book to date., June 13, 2010
By 
Dan (Calgary, AB Canada) - See all my reviews
(REAL NAME)   
This review is from: Wireshark Network Analysis: The Official Wireshark Certified Network Analyst Study Guide (Paperback)
I saw this book in the Tech Ed 2010 book store the day before Laura's session and thought $99 - you've got to be kidding! After seeing her present in her first session, my opinion changed completely and I rushed (along with many other attendees at the session) directly to the bookstore down the hall to grab a copy.

Needless to say the book sold out immediately and I was lucky to have obtained one.

I have been in the Networking industry for close to 20 years, and Laura has the unique ability to make this material understandable and accessible for anyone that has basic network knowledge. Coupled with her sense of humor, it enables one to tackle this esoteric topic and even enjoy it along the way.

This book has enabled me to "fill in the gaps" in my network analysis skill set and I look forward to referring to it for a long time to come.

Great job Laura, I look forward to seeing more material from you in the future!
