Number: RL32631 Title: Critical Infrastructure and Key Assets: Definition and Identification Authors: John Moteff and Paul W. Parfomak, Resources, Science, and Industry Division Abstract: This report reviews the concept and definition of critical infrastructure as it has appeared in federal reports, legislation and regulation since the early 1980s. The report highlights the changes and expansion of that definition as the focus of public policy debates shifted from infrastructure adequacy to infrastructure protection. Finally the report summarizes current policy issues associated with critical infrastructure identification by federal agencies and the private sector. The report is intentionally limited to definitional issues and categorization of infrastructure. For a more general discussion of national policy regarding critical infrastructure protection, including its evolution, implementation, and continuing issues, see CRS Report RL30153, Critical Infrastructures: Background, Policy, and Implementation.
