Applying Public Health Systematic Approaches to Cybersecurity: The Economics of Collective Defense

The U.S. public health system increased life expectancy by more than 30 years since 1900 through systematic data collection, evidence-based intervention, and coordinated response. This paper examines whether cybersecurity can benefit from similar organizational principles. We find that both domai...
