Managing cyber risk requires avoiding the mistakes of the past, understanding how to navigate within a layered security environment, and an appreciation of when best practices are likely to fail. This course develops a firm understanding of cybersecurity concepts and recent history through case studies of cyberattacks and responses. Students will develop an appreciation for how the U.S. government's approach to cybersecurity has changed over time. Students will apply analytical tools to the policy problems created by that system, such as how the current system leads to gaps between the Federal and state governments, government and the private sector, and various nations. Given the ever evolving nature of cyber risk, this course will examine how these policies are playing out against current attacks highlighted in unclassified sources.
