After reading chapter 1 and looking at the link above, you’re ready to participate in the first discussion.
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:
1) Create a new thread. As indicated above, please explain how DHS should handle the situation described in the preceding paragraph.
2) Select AT LEAST 2 other students’ threads and post substantive comments on those threads. Your comments should extend the conversation started with the thread. 
To guide your discussions, please consider the following questions:

What did you learn from your classmate’s posting? 
What additional questions do you have after reading the posting? 
What clarification do you need regarding the posting? 
What differences or similarities do you see between your posting and other classmates’ postings?
