Critical infrastructure protection is becoming increasingly important in the 21st century, but the people in charge of defending and regulating the different sectors often do not know enough about the systems themselves to make proper decisions. The course aims to provide students with foundational understandings of what critical infrastructure is and how it relates to cyber- threat intelligence for decision-makers. The course material is designed to give students the tools they need to think critically about cyber threats to critical infrastructure and the assignments are designed to give students flexibility on what to dig into.
