Description

Wireshark is a widely used open source tool to profile and monitor network traffic and analyze packets. It basically lets you control, capture, and dynamically browse the traffic running on the organization's network. This video will teach you about the new Wireshark 2, with enhanced features to help you protect your organization in a better way.

We'll start with brushing up on the various network protocols, OSI layers, and the role of Wireshark. We'll show you the importance of analyzing the network, as if ignored, this can lead to a catastrophe. Then we introducing you to Wireshark 2 and demonstrate its installation and configuration.

The major update in Wireshark 2 was in the interface, so we will expose you to the rich new user interface and show you how it's better than the previous version. Moving ahead, we'll focus on Wireshark's core functionalities such as Packet Analysis, IP filtering, and Protocol filters. You'll see how Wireshark 2 can be used to secure your network. Finally, we'll focus on Packet Analysis for security tasks, command-line utilities, and tools that manage trace files.
