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.

Discovering CloudShark

Most of us would agree that Wireshark is a great tool for troubleshooting, along with identifying malware and other anomalies on a network. However, Wireshark has some limitations in that it must be installed on a local machine to gather traffic, and it can be resource-intensive. In addition, Wireshark is not designed to be used concurrently by multiple people, such as in a team.

CS is a browser-based Software as a Service (SaaS) that provides a way to upload packet captures and share them with co-workers or even the world. You can also do an analysis on the fly, or simply use it as a browser-based solution to learn about protocol behavior.

CS offers the following features:

  • Capture Index, where you can store and share captures
  • The main interface, where you can apply filters and add notes
  • The ability to conduct advanced analysis and threat evaluation
