real-world scenario question

Let’s look at a real-world scenario and how the Department of Homeland Security (DHS) plays into it. In the scenario, 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 Defense’s [DOD’s] ability to communicate with commands overseas). International commerce and financial institutions are also severely hit. Please explain how DHS should handle this situation.

You must do the following:

As indicated above, please explain how DHS should handle the situation described in the preceding paragraph. Must use a minimum of three unique scholarly references for your post. Also, please cite all references, in-text citations and use proper APA formatting. Answer must be atleast 400 words.
