Mastering Wireshark 2

By: Andrew Crouthamel

Overview of this book

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.

Installing Wireshark 2


So in this chapter, you've learned about some email analysis using POP and SMTP. We also looked at 802.11, which is wireless, what certain things look like in a packet capture, and the fact that you'll need to do additional troubleshooting outside of what you can do in Wireshark in order to properly diagnose wireless. We also looked at VoIP analysis using SIP and RTP, creating that connection and then transmitting that audio data directly from one device to another. Then, we also played that back using the built-in tools in Wireshark, and manipulated some of the settings in that for jitter, in order to recreate problems and be able to listen to what that sounds like.

Next is Chapter 10, Command-Line Tools, where we'll use some command-line tools to extend Wireshark, and talk about some of the enhancements that you can add to it.
