Chapter 1 provided a high-level overview of the need for a national framework for protecting critical infrastructure. For some additional reading, take a look at the latest Presidential Order that relates to strengthening cybersecurity that relates to critical infrastructure: 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 3 other students' threads and post substantive comments on those threads. Your comments should extend the conversation started with the thread. ALL original posts and comments must be substantive. (I'm looking for about a paragraph - not just "I agree.") 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? Week 1 discussion (Chapter 1) Due date is 05/10/2019 on Friday

Paper For Above instruction

The Department of Homeland Security (DHS) plays a vital role in responding to large-scale cybersecurity crises such as the scenario described, where coordinated cyberattacks incapacitate critical infrastructure across the United States. To effectively handle such a situation, DHS must adopt a comprehensive, multi-layered approach that incorporates immediate response, strategic coordination, and long-term resilience planning.

Immediately following the cyberattack, DHS should activate its National Cybersecurity and Communications Integration Center (NCCIC), which functions as a central hub for cyber threat analysis and incident response. The NCCIC's primary role is to coordinate efforts across federal, state, local, tribal, and private sector partners to mitigate impact and contain the spread of the attack. In doing so, DHS should work closely with the Department of Defense (DOD), Federal Emergency Management Agency (FEMA), and private sector stakeholders to stabilize systems and prioritize critical infrastructure sectors such as energy, communications, transportation, and finance.

Given the scope of the attack, DHS should also initiate an all-hands-on-deck approach, leveraging an incident management framework aligned with the National Response Framework (NRF). This involves establishing a unified command structure that ensures a coordinated effort across agencies and jurisdictions. The usage of cyber emergency response teams (CERTs) and cybersecurity task forces would be instrumental in providing specialized expertise to counteract the attack and restore affected systems.

In addition to immediate response efforts, DHS should facilitate crisis communication strategies to inform the public, government officials, and international partners without inciting panic. Clear, accurate, and timely information dissemination is crucial to maintain confidence and enable coordinated response efforts globally and domestically.

Since this scenario involves a cyber attack disrupting national security and economic stability, DHS should work closely with the President and Congress to invoke emergency powers and allocate necessary resources. Cyberattack scenarios of this magnitude also require long-term strategic planning; DHS should prioritize strengthening resilience by emphasizing cybersecurity infrastructure enhancements, developing redundant systems, and creating rapid response capabilities for future incidents.

Furthermore, DHS should revisit and strengthen its partnerships with international agencies to facilitate information sharing and coordinated responses. Cyber threats are global, and collaboration with allies and international organizations is vital to mitigate future incidents and respond effectively when attacks originate from foreign adversaries like China. Overall, DHS’s handling of such a crisis depends on swift, coordinated response efforts combined with strategic planning to bolster resilience and defend against future threats.
