This interactive lecture course will explore various legal and policy issues related to enabling a safe and secure Internet and protecting government and private sector networks. The topics to be discussed include relevant U.S. legal authorities, cybersecurity roles and responsibilities of government agencies, private sector cybersecurity risk management, information sharing, Internet governance, and the application of international law to nation state activity in cyberspace. Lectures by the professor and occasional guests with relevant expertise will be used to stimulate class discussion. Students will be assigned a short, ungraded (credit/no credit) reflection assignment to prepare for an in-class table top exercise, and an oral presentation on a topic selected by the student from a list provided by the professor. There will be a four-hour take-home exam that must be completed during the first week of the exam period.
