Modern society depends on robust and resilient critical infrastructure. Our health system relies on energy, water, transport, information and communications technology, and other services, just as those sectors depend on essential services from health organizations and providers. Interdependencies within and between sectors are becoming increasingly complex. The rate and severity of natural disasters is also increasing, as is our overall connectivity and dependence on information and communication technologies.
Understanding and mitigating risks posed by potential hazards is essential to the resilience of our critical infrastructure. This requires an integrated perspective since vulnerabilities in one area can have cascading effects across organizational boundaries, sectors, and borders.
