Overview of this book

Wireshark is a popular and powerful packet analysis tool that helps network administrators investigate latency issues and potential attacks. Over the years, there have been many enhancements to Wireshark’s functionality. This book will guide you through essential features so you can capture, display, and filter data with ease. In addition to this, you’ll gain valuable tips on lesser-known configuration options, which will allow you to complete your analysis in an environment customized to suit your needs. This updated second edition of Learn Wireshark starts by outlining the benefits of traffic analysis. You’ll discover the process of installing Wireshark and become more familiar with the interface. Next, you’ll focus on the Internet Suite and then explore deep packet analysis of common protocols such as DNS, DHCP, HTTP, and ARP. The book also guides you through working with the expert system to detect network latency issues, create I/O and stream graphs, subset traffic, and save and export captures. Finally, you’ll understand how to share captures using CloudShark, a browser-based solution for analyzing packet captures. By the end of this Wireshark book, you’ll have the skills and hands-on experience you need to conduct deep packet analysis of common protocols and network troubleshooting as well as identify security issues.

Summary

By now, you understand the many different types of networks that can influence how data travels. In addition to the various network types, we saw how we must also contend with the media that transmits the data. So that you can effectively capture traffic, we took a closer look at various capture selections that include display options, using multiple files, and name resolution.

We then moved into a discussion of the different types of traffic you will see when tapping into a switched network and compared the difference between conversations and endpoints. We then looked at the many options for analysis within the Conversations window. Finally, we summarized the importance of baselining the network and provided some steps on how to move through this process.

In the next chapter, we will discover the many ways to personalize the Wireshark interface. You will learn ways to adjust the appearance and basic layout. I'll show you ways to add, modify, and personalize the...
