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


In this chapter, we've learned about BPF syntax and its history and how to create BPF syntax. We also saw how to use that BPF and then apply it as a capture filter and reduce the packets that we end up capturing on our capturing interface. We then saw how to create and use display filters to prune what we have in a packet capture to what we just need to see. Furthermore, we saw how to follow streams, both TCP and UDP streams, so that we can view specific conversations within a packet capture and export that data if required. We also saw how to go into the different packet fields and lengths and all the different pieces of data within the headers of the packets and be able to create filters based on them.

In Chapter 4, Customizing Wireshark, we'll start tweaking Wireshark and actually customizing it and creating our own preferences and profiles so that we can make Wireshark our own.
