From hackers to hurricanes, suicide bombing to supply chain interruptions, infrastructure failures to infectious disease outbreaks, the nation's governments, companies and non-profits must prepare for, protect against, respond to, and recover from a growing array of risks and threats. The fields of emergency preparedness, homeland security and cybersecurity are central to those efforts, and there is an ever growing demand for individuals prepared in these areas. Through lectures, discussion, and case studies, students in this course will develop a broad theoretical, substantive, and practical understanding of the fields of emergency preparedness, homeland security and cybersecurity. Students will be exposed to various ways to think about, measure, assess and compare risks, as well as how to mitigate them and respond to incidents that do occur. The three disciplines will be explored through the crosscutting themes that tie them together, including prevention, incident management and response, crisis communication, recovery and resiliency.
