Overview of this book

Wireshark is a popular and powerful tool used to analyze the amount of bits and bytes that are flowing through a network. Wireshark deals with the second to seventh layer of network protocols, and the analysis made is presented in a human readable form. Mastering Wireshark will help you raise your knowledge to an expert level. At the start of the book, you will be taught how to install Wireshark, and will be introduced to its interface so you understand all its functionalities. Moving forward, you will discover different ways to create and use capture and display filters. Halfway through the book, you’ll be mastering the features of Wireshark, analyzing different layers of the network protocol, looking for any anomalies. As you reach to the end of the book, you will be taught how to use Wireshark for network security analysis and configure it for troubleshooting purposes.

A brief overview of the TCP/IP model

Next, it's time to discuss the most important topic in the world of networking. In order to understand how all these things stick together, we need to understand the basics of the TCP/IP model. Even the world of computers needs a set of rules and regulations to communicate, and this is taken care by the networking protocols, which govern the transmission of packets/segments/frames over a dedicated channel between hosts.

The TCP/IP model was originally known as the DoD model, and the project was regulated by United States Department of Defense. The TCP/IP model takes care of every aspect of every packet's life cycle, namely, how a packet is generated, how a single packet gets attached with a required set of information (PDU), how a packet is transmitted, how it comes to life, how it is routed through to intermediary nodes to the destination, how it is integrated back with other packets to get the whole information out, and so on.

If you have any confusion regarding the basics of networking protocols, I would recommend that you do a quick revision before proceeding ahead, as this book requires familiarity with the TCP/UDP protocols. By the time you come back, you will be able to visualize and answer all of these questions on your own.
