Homeland Security, Infrastructure Security

Assume you have been appointed chair of a public/private partnership (consortium) involving members of the transportation, cyber, and various infrastructure communities such as factories and transportation systems (roads, rails, air, and waterways). This disparate group has a wide variety of concerns, but all share a concern about security. They will meet and work in subcommittees later, but they want you to guide them in the right direction. Provide a high level and brief overview of the threats we face and provide a high-level list of mitigation strategies they can employ for the industries and infrastructures listed above.
