Critical infrastructure, also referred to as nationally significant infrastructure, can be broadly defined as the systems, assets, facilities, and networks that provide essential services and are necessary for the national security, economic security, prosperity, and health and safety of their respective nations. The primary focus of disaster and emergency management is the protection of people, the environment, property, and the economy. Therefore, understanding critical infrastructure and how to protect it is essential for disaster and emergency management professionals across all economic sectors. Students will learn about the different critical infrastructure sectors, how they are interconnected and integrated, and the implications of dependent systems for activities across the mitigation, preparedness, response, and recovery spectrum. This course will employ case studies extensively to enable students to directly apply the material to real-world scenarios.
