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.

Chapter 20: Using CloudShark for Packet Analysis

Although Wireshark is a powerful, versatile tool, there are times when you may need to involve your team in a packet analysis exercise. One site that makes it easy to share your packet captures with co-workers is CloudShark (CS). CS does not have as many features as Wireshark; however, you can still complete a number of functional tasks during an analysis. In this chapter, we'll discover CS, a browser-based solution that offers several of the same benefits as Wireshark.

You'll learn that, in addition to the basic tasks, you can create an account and perform more advanced functions such as uploading and sharing captures. So that you can get the full benefit of CS, we'll step through basic packet capture analysis, such as applying filters to narrow the scope. In addition, we'll learn how to create graphs that provide a visual representation of the data. We'll also explore some of the built-in analysis tools...
