This course provides a comprehensive introduction to the issues surrounding the regulation and governance of cyberspace. Contrary to John Perry Barlow’s “Declaration of the Independence of Cyberspace” in 1996, cyberspace has become an arena for national and international regulation. Increased awareness of cyber threats and risks resulting in efforts to enhance cybersecurity has only added to this development. This course traces the various regulatory efforts in this space to investigate which institutions, norms, and processes govern the behavior of different actors, including states, companies, and individuals. Discussions will cover, among other things, Internet governance, norms of responsible state behavior during times of armed conflict as well as during peace time, human rights online, surveillance and data collection, as well as cybercrime.
