One approach is to use whats called a mirror or span port on your switch.
Lifting up the hood of a car is the best way to understand how an internal combustion engine works, and likewise lifting the lid on network traffic and watching packets fly by - even drilling down to the byte level, and examining TCP headers - is a powerful way to learn, and teach others how the internet works.ĭemystifying the motor that runs our information economy can only lead to better-informed business decisions and better government policy, not to mention a better-qualified workforce. There are so many hands-on uses for Wireshark that it’s easy to overlook what an effective learning tool it can be. This makes it easy to spot general trends, and to present findings to less-technical management. Wireshark comes with graphical tools to visualize the statistics. Having a solid understanding of the capabilities can. Symmetric session keys are stored in the browser, and with the appropriate browser setting (and permission and knowledge of the user) an administrator can load those session keys into Wireshark and examine unencrypted web traffic.
