Wireshark Network Analysis Masterclass

Wireshark Network Analysis Masterclass equips you with the skills to capture, analyse and troubleshoot network traffic using Wireshark, the world's most widely used network protocol analyser. Wireshark lets you see exactly what is happening on your network, making it invaluable for diagnosing performance problems, investigating security incidents and understanding how applications communicate. The masterclass is designed for network administrators, security analysts, IT support engineers and anyone responsible for keeping networks running smoothly.

You will start with an introduction to network analysis and Wireshark, understanding packet capture, the Wireshark interface and how to open and navigate trace files. Next you will learn capture methods and how to use capture filters, including where to capture on switched, wireless and virtual networks. You will then customise Wireshark for efficiency, configuring global and personal preferences and profiles, and learn to navigate quickly and focus faster with colouring rules, display filters, columns and time settings.

The course continues with analysing key protocols such as Ethernet, IP, TCP, UDP, DNS, DHCP and HTTP, following streams, using the expert information system and statistics, and graphing traffic to identify latency, packet loss and retransmissions. You will also apply Wireshark to detecting suspicious and malicious traffic. Every topic is hands-on with real trace files. By the end of the masterclass, you will be able to use Wireshark confidently to troubleshoot network problems and investigate security issues.
