The U.S. reliance on critical infrastructures.

Discuss U.S. reliance on critical infrastructures. If the U.S. suffered a major nationwide cyber attack, which of these critical infrastructures would be most impacted? Consider what daily activities or resources they would no longer be able to participate in or use. Many of you will realize such an attack’s effect on the internet, cell phones, etc., but they may not consider its impact on water supplies or modes of transportation. Please be detailed in your response.
