Who This Book Is For

If you are a security professional or a network enthusiast and are interested in understanding the internal working of networks, and if you have some prior knowledge of using Wireshark, then this book is for you.

What You Will Learn
  • Understand what network and protocol analysis is and how it can help you
  • Use Wireshark to capture packets in your network
  • Filter captured traffic to only show what you need
  • Explore useful statistic displays to make it easier to diagnose issues
  • Customize Wireshark to your own specifications
  • Analyze common network and network application protocols
In Detail

Wireshark, a combination of a Linux distro (Kali) and an open source security framework (Metasploit), is a popular and powerful tool. Wireshark is mainly used to analyze the bits and bytes that flow through a network. It efficiently deals with the second to the seventh layer of network protocols, and the analysis made is presented in a form that can be easily read by people.

Mastering Wireshark 2 helps you gain expertise in securing your network. We start with installing and setting up Wireshark2.0, and then explore its interface in order to understand all of its functionalities. As you progress through the chapters, you will discover different ways to create, use, capture, and display filters. By halfway through the book, you will have mastered Wireshark features, analyzed different layers of the network protocol, and searched for anomalies. You'll learn about plugins and APIs in depth. Finally, the book focuses on pocket analysis for security tasks, command-line utilities, and tools that manage trace files.

By the end of the book, you'll have learned how to use Wireshark for network security analysis and configured it for troubleshooting purposes.

Style and approach

This step-by-step guide on Wireshark 2 starts with capturing and filtering traffic and follows with analysis and statistics, as well as all the new features of Wireshark 2.
