Beneath the mundane world of TCP/IP exists the magical and mysterious realm of ethernet. There are many different types of ethernet protocols in use today, known as ‘ethertypes’, that run the gamut from the boutique to the ubiquitous. In this talk, we will delve into some of the more interesting and obscure ethertypes that exist. We will discuss the network protocols themselves, where they can be found in the wild, what you can do with them, and how they could be abused in the wrong hands. We will explore wide-ranges of networking environments including industrial/facilities, transportation, and medical, and will include several live demos. Attendees will leave this talk with a greater understanding and appreciation for the unseen networking world that exists all around them.
