If you are in to Critical Infrastructure Protection (CIP), you need to read this article. It is a very long read, but well worth it. Give's a great indepth description of CIP and where it's headed.
The eighteen Critical Infrastructure and Key Resource (CIKR) sectors are defined as:
| Agriculture and Food | Water | Nuclear Reactors |
| Defense Industrial Base | Chemical | Information Technology |
| Energy | Commercial Facilities | Communications |
| Healthcare and Public Health | Critical Manufacturing | Postal & Shipping |
| National Monuments & Icons | Dams | Transportation Systems |
| Banking and Finance | Emergency Services | Government Facilities |
The events of September 11, 2001 brought about a rapid expansion of critical infrastructure protection efforts. The first National Strategy for Homeland Security was published in 2002 and was followed by the National Strategy for the Physical Protection of Critical Infrastructures and Key Assets and Homeland Security Presidential Directive 7, which replaced PDD63, in 2003. These documents expanded critical infrastructure to thirteen sectors and added five key resources and led to the publication of the first National Infrastructure Protection Plan (NIPP) in 2006, with the second edition following in 2009. Currently, the NIPP defines Critical Infrastructure as:3
Systems and assets, whether physical or virtual, so vital that the incapacity or destruction of such may have a debilitating impact on the security, economy, public health or safety, environment, or any combination of these matters, across any Federal, State, regional, territorial, or local jurisdiction.
