Learn Wireshark: Confidently navigate the Wireshark interface and solve real-world networking problems

Book Description
Wireshark is a popular and powerful packet analysis tool that helps network administrators investigate latency issues and identify potential attacks.

Learn Wireshark provides a solid overview of basic protocol analysis and helps you to navigate the Wireshark interface, so you can confidently examine common protocols such as TCP, IP, and ICMP. The book starts by outlining the benefits of traffic analysis, takes you through the evolution of Wireshark, and then covers the phases of packet analysis. We’ll review some of the command line tools and outline how to download and install Wireshark on either a PC or MAC. You’ll gain a better understanding of what happens when you tap into the data stream, and learn how to personalize the Wireshark interface. This Wireshark book compares the display and capture filters and summarizes the OSI model and data encapsulation. You’ll gain insights into the protocols that move data in the TCP/IP suite, and dissect the TCP handshake and teardown process. As you advance, you’ll explore ways to troubleshoot network latency issues, and discover how to save and export files. Finally, you’ll see how you can share captures with your colleagues using Cloudshark.

By the end of this book, you’ll have a solid understanding of how to monitor and secure your network with the most updated version of Wireshark.
