An infrastructure is a set of facilities and processes that provide a foundation for human civilization. Between 1996 and 1997, a list of eight critical infrastructures was established, and the President's Commission on Critical Infrastructure Protection produced a report on how to defend these infrastructures. The report spurred extensive activity both in government and in the private sector.

Interest remains at a high level, and many persons are planning a career in infrastructure assurance. At infrastructure.org, we offer a description of each of the eight infrastructures, noting the threats and providing references to current responses. The presentations can help you learn about

• why each infrastructure is important
• what major items are included in an infrastructure
• how engineers and planners have studied an infrastructure
