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: https://www.whitehouse.gov/presidential-actions/presidential-executive-order-strengthening-cybersecurity-federal-networks-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. 1) Create a new thread. As indicated above, 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.

The Department of Homeland Security (DHS) plays a crucial role in handling a large-scale, coordinated cyber attack that cripples various sectors of the United States, including government agencies, critical infrastructure, and commercial ventures. In this scenario where the attack is orchestrated by China, DHS must implement a comprehensive strategy to mitigate the damage and restore normalcy.

Firstly, DHS should activate the National Cybersecurity and Communications Integration Center (NCCIC) to lead the response efforts. The NCCIC serves as the 24/7 cyber situational awareness, incident response, and management center for the federal government. Its role in this situation would be to provide real-time analysis of the attack and coordinate with the affected agencies, critical infrastructure operators, and private sector entities. By quickly identifying the attack patterns and sharing threat intelligence, NCCIC can enable a more coordinated and effective response.

To address the paralysis of IT infrastructure in government agencies, DHS should work closely with the affected entities to initiate incident response and recovery procedures. This involves isolating affected systems, determining the extent of compromise, and developing a plan to restore services. DHS can provide technical assistance through its U.S. Computer Emergency Readiness Team (US-CERT) to help these agencies recover their systems and enhance their cybersecurity posture.

In terms of the disrupted electric grid, DHS should collaborate with the Department of Energy (DOE) and relevant industry partners to assess the extent of the damage and expedite restoration efforts. The Cybersecurity and Infrastructure Security Agency (CISA), within DHS, can play a key role in coordinating communication between government agencies and private sector entities responsible for the operation of critical infrastructure. By leveraging their expertise in the energy sector, DHS can prioritize the restoration of power to essential facilities and gradually bring the grid back online.

Addressing the limitations in telephone and satellite communications is critical for the Department of Defense (DOD) to maintain command and control capabilities. DHS should work in tandem with the DOD to identify alternative communication channels, such as secure military satellites or backup terrestrial systems, to ensure uninterrupted communication with overseas commands.

Additionally, DHS should engage in international collaboration to address the impact on commerce and financial institutions. Through existing partnerships and forums, such as the International Cyber Threat Intelligence Collaboration Group, DHS can collaborate with other nations to share information, identify the perpetrators, and impose consequences on the responsible actors. This multilateral approach will not only strengthen the response effort but also deter future cyber attacks.

Overall, in a scenario where the United States faces a large-scale cyber attack orchestrated by China, DHS must coordinate efforts across government agencies, critical infrastructure operators, and private sector entities to mitigate the damage and restore normalcy. By leveraging the capabilities of NCCIC, US-CERT, CISA, and collaborating with partner organizations, DHS can effectively address the challenges posed by the attack and strengthen the resilience of the nation’s cybersecurity infrastructure.
