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, you learned about the UDP protocol and its connectionless abilities—the very small header that it has, all the different fields in the TCP header, and the options that are available in it.

We also looked at TCP, the connection-oriented protocol, and the guaranteed transmission of certain data. We looked at the header and learned about the fact that it has different flags and different options to expand upon its capabilities. We also learned about the graphing functionality in Wireshark, and the fact that you can add multiple layers and change the way the lines and bar charts work, in order to get the most useful graph out of it.

In Chapter 8, Application Protocol Analysis I, we will take a look at HTTP and FTP, and some of the common applications that you'll run across on a day-to-day basis.
