Lots of people teach "information security", but far fewer research and discuss physical security in large-scale networks, including university environments. There are many ways to own a campus, and given the time we have, we'll address as many as we can. The goal of the course is to give you a nuanced view of physical security, including movement sensors, magnetic and RFID card readers, and master-keyed physical lock systems. We will also discuss the social implication of the use and abuse of these systems.
