Understand the fundamentals of the Wireshark tool that is key for
network engineers and network security analysts. This book explains how
the Wireshark tool can be used to analyze network traffic and teaches
you network protocols and features.
Author Vinit Jain walks you through the use of Wireshark to analyze
network traffic by expanding each section of a header and examining its
value. Performing packet capture and analyzing network traffic can be a
complex, time-consuming, and tedious task. With the help of this book,
you will use the Wireshark tool to its full potential. You will be able
to build a strong foundation and know how Layer 2, 3, and 4 traffic
behave, how various routing protocols and the Overlay Protocol function,
and you will become familiar with their packet structure.
Troubleshooting engineers will learn how to analyze traffic and identify
issues in the network related to packet loss, bursty traffic, voice
quality issues, etc. The book will help you understand the challenges
faced in any network environment and how packet capture tools can be
used to identify and isolate those issues.
This hands-on guide teaches you how to perform various lab tasks. By the
end of the book, you will have in-depth knowledge of the Wireshark tool
and its features, including filtering and traffic analysis through
graphs. You will know how to analyze traffic, find patterns of offending
traffic, and secure your network.
What You Will Learn
- Understand the architecture of Wireshark on different operating
systems
- Analyze Layer 2 and 3 traffic frames
- Analyze routing protocol traffic
- Troubleshoot using Wireshark Graphs
