Need for a national framework for protecting critical infrastructure. Overview of https://www.whitehouse.gov/presidential-actions/presidential-executive-order-strengthening-cybersecurity-federal-networks-critical-infrastructure/. Please explain how DHS should handle the below situation from the above link & need for a national framework for protecting critical infrastructure. The United States will be hit by a large-scale, coordinated cyber-attack organized by China. These attacks debilitate the functioning of government agencies, parts of the critical infrastructure, and commercial ventures. The IT infrastructure of several agencies are paralyzed, the electric grid in most of the country is shut down, telephone traffic is seriously limited, and satellite communications are down (limiting the Department of Defenses [DODs] ability to communicate with commands overseas). International commerce and financial institutions are also severely hit.
