<p>Wireshark is the world's foremost and most widely-used network protocol analyzer. It lets you see what's happening on your network at a microscopic level. Wireshark deals with the second to the seventh layers of network protocols, and the analysis made is presented in a human-readable form. It is used for network troubleshooting, analysis, software, and communications protocol development.</p> <p>This course starts setting up a Wireshark lab in the Windows and Linux operating systems. We dive into the overall process of packet capturing and Wireshark filters. Then, we introduce tshark, a command line-version of Wireshark, and we learn about various tshark commands. Later, we are introduced to various types of network cyber attack and essential remedies. We also go through an array of techniques to monitor and secure these attacks using Wireshark. Lastly, we cover network troubleshooting using Wireshark.</p> <p>Towards the end of the course, you'll use Wireshark efficiently to find primary sources of network performance problems and also different ways to secure networks.</p> <h1>Style and Approach</h1> <p>This course aims to provide complete coverage of every objective in Wireshark. The course is filled with apt and concise demonstrations and explanations to help you to understand Wireshark and its uses.</p>
