Sinopse: Critical infrastructure includes the assets, systems, facilities, networks, and other elements that society relies upon to maintain national security, economic vitality, and public health and safety. We know critical infrastructure as the power used in homes, the water we drink, the transportation that moves us, the stores where we shop, and the Internet and communications we rely on to maintain our contact with friends, family, and colleagues. In the U.S., this physical and cyber infrastructure is typically owned and operated by the private sector, though some is owned by federal, state, or local governments. Not all infrastructure within an industry sector is critical to a nation or region. It is necessary to identify which infrastructure is both critical to maintain continued services or functions and vulnerable to some type of threat or hazard. Prioritizing the allocation of available resources to that subset of infrastructure can enhance a nation’s security, increase resiliency, and reduce risk.
