Wireshark is the world's most popular network analyzer solution.
Used for network troubleshooting, forensics, optimization and more, Wireshark is considered one of the most successful open source projects of all time.
Laura Chappell has been involved in the Wireshark project since its infancy (when it was called Ethereal) and is considered the foremost authority on network protocol analysis and forensics using Wireshark.
This book consists of 16 labs and is based on the format Laura introduced to trade show audiences over ten years ago through her highly acclaimed Packet Challenges.
This book gives you a chance to test your knowledge of Wireshark and TCP/IP communications analysis by posing a series of questions related to a trace file and then providing Laura's highly detailed step-by-step instructions showing how Laura arrived at the answers to the labs.
Book trace files and blank Answer Sheets can be downloaded from this book's supplement page (see https: //www.
