Definition
Geospatial data
Infrastructure is
| “ | [a] reliable, supporting environment, analogous to a road or telecommunications network, that facilitates the access to geographically-related information using a minimum set of standard practices, protocols and specifications.[1] | ” |
Information technology
Infrastructure means the computer and communication hardware, software, databases, people, and policies supporting an enterprise’s information management functions.
Security
Infrastructure is the framework of interdependent networks and systems comprising identifiable industries, institutions (including people and procedures), and distribution capabilities that provide a reliable flow of products and services essential to the defense and economic security of the United States, the smooth functioning of government at all levels, and society as a whole.[2]
Consistent with the definition in the Homeland Security Act of 2002, infrastructure includes physical, cyber, and/or human elements.
Vulnerabilities
Real vulnerabilities also exist. Infrastructures have always been subject to local or regional outages resulting from earthquakes, storms, and floods. Their owners and operators, in cooperation with local, state, and federal emergency services, have demonstrated their capacity to restore services efficiently. Physical vulnerabilities to man-made threats, such as arson and bombs, are likewise not new. But physical vulnerabilities take on added significance as new capabilities to exploit them emerge, including chemical, biological, and even nuclear weapons. As weapons of mass destruction proliferate, the likelihood of their use by terrorists increases.
