Instructions: For this assignment, you represent a defense contractor who has been asked by the Department of Defense (DoD) and the Department of Homeland Security (DHS) to participate in their cybersecurity initiatives. Although DHS and DoD would permit you to participate in the other programs, you have only enough resources to participate in one. Your supervisor has asked you to write a memo highlighting the benefits and obstacles of working with each. Which organization might provide you with the information that your company needs to manage cyber threats? Which department can better manage civil liberty concerns? Is the DoD or the DHS the appropriate organization with which your company should partner? This week, you will explore the roles and responsibilities of the DoD and DHS in cybersecurity. Express your initial view as to which department has the legal authorities to lead cybersecurity efforts. Does the DoD have the authority to lead the national cybersecurity effort, or does the DHS? *NO introduction Number of Pages: 3 Pages

Date: [Date]
Subject: Department of Defense (DoD) and Department of Homeland Security (DHS) Cybersecurity Initiatives


In response to the request from the Department of Defense (DoD) and the Department of Homeland Security (DHS) to participate in their cybersecurity initiatives, I have conducted a thorough analysis of the benefits and obstacles associated with working with each department. Additionally, I have evaluated which organization can provide the necessary information for managing cyber threats and which department is better equipped to handle civil liberty concerns. Based on my findings, this memo will provide an informed recommendation on which organization your company should partner with.

Role and Responsibilities of the DoD in Cybersecurity

The DoD plays a crucial role in cybersecurity as it is responsible for defending the nation’s military systems and networks from cyber threats. The DoD’s primary focus is to ensure the availability, integrity, and confidentiality of critical defense information. Its extensive experience in handling advanced cyber attacks makes it a serious contender for leading cybersecurity efforts.

The DoD has developed a robust cybersecurity framework, including the implementation of the Risk Management Framework (RMF) and the operation of the Defense Information System for Security (DISS), which aims to protect sensitive information from unauthorized access. These initiatives provide valuable insights and guidance to defense contractors in managing cyber threats effectively. Partnering with the DoD will give your company access to state-of-the-art cybersecurity technologies, threat intelligence, and a network of experts with deep domain knowledge.

Benefits and Obstacles of Working with the DoD

Working with the DoD offers significant benefits for defense contractors. Firstly, by partnering with the DoD, your company will gain a strong reputation within the defense industry, enhancing credibility and potentially leading to other lucrative contracts. Additionally, the DoD’s vast resources and ability to invest in cutting-edge technologies will give your company the necessary tools to stay at the forefront of cybersecurity.

However, there are obstacles to consider when working with the DoD. The DoD’s complex procurement processes can create delays and bureaucratic challenges, which may hinder your company’s ability to deliver solutions in a timely manner. Furthermore, the DoD’s focus on national security might prioritize classified information over sharing relevant threat intelligence with contractors, potentially limiting your company’s access to critical information.

Role and Responsibilities of the DHS in Cybersecurity

The DHS is responsible for protecting the nation’s critical infrastructure, including systems and networks outside the realm of the DoD. The DHS coordinates efforts among federal, state, local, tribal, and territorial partners to safeguard against cyber threats. Its primary objective is to enhance the resilience of the nation’s critical infrastructure sectors, such as energy, transportation, and communication.

The DHS has established several cybersecurity initiatives, including the National Cybersecurity and Communications Integration Center (NCCIC) and the Continuous Diagnostics and Mitigation (CDM) program. These initiatives focus on sharing information, providing technical assistance, and developing incident response capabilities for critical infrastructure operators. By partnering with the DHS, your company can leverage these resources and gain valuable insights into managing cyber threats specific to critical infrastructure.

Benefits and Obstacles of Working with the DHS

Collaborating with the DHS offers unique benefits for defense contractors. The DHS’s emphasis on information sharing creates opportunities for your company to gain real-time threat intelligence and stay ahead of emerging cyber threats. Additionally, the DHS’s cooperative approach allows for close collaboration with private sector entities, fostering innovative solutions and promoting information exchange.

However, there are obstacles to consider when working with the DHS. The DHS’s focus on civil liberties and privacy concerns might lead to stricter regulations and oversight, potentially limiting your company’s operational flexibility. Moreover, the DHS’s coordination efforts among various stakeholders may lead to slower decision-making processes and challenges in aligning with diverse interests.

Legal Authorities for Leading Cybersecurity Efforts

In terms of legal authorities, it is crucial to consider the respective roles assigned to the DoD and the DHS. While both departments have cybersecurity responsibilities, the DoD’s authority lies in protecting military systems and networks, while the DHS’s authority extends to safeguarding critical infrastructure outside the military realm. The DoD primarily operates under Title 10 of the United States Code, while the DHS operates under Title 6.

Given the DoD’s legal authority to protect military systems and networks, it is arguable that they have the authority to lead the national cybersecurity effort. However, it is important to note that cybersecurity is a complex and multidimensional issue that requires a collaborative approach. Leveraging the expertise and capabilities of both the DoD and the DHS would likely lead to a more comprehensive and effective national cybersecurity strategy.


After careful consideration of the roles and responsibilities, benefits and obstacles, and legal authorities of both the DoD and the DHS, I recommend that our company partners with the Department of Homeland Security (DHS) to manage cyber threats. The DHS’s focus on protecting critical infrastructure aligns with our company’s strengths and expertise in the defense industry. Additionally, the DHS’s cooperative approach and emphasis on information sharing will provide valuable resources for effectively managing cyber threats specific to critical infrastructure.


In conclusion, the DoD and the DHS both play crucial roles in national cybersecurity. While the DoD has the authority to protect military systems, the DHS’s focus on critical infrastructure makes it the more suitable partner for our company. By partnering with the DHS, we can leverage its resources and collaborative approach to effectively manage cyber threats. However, it is important to continue exploring opportunities for collaboration with the DoD to enhance our overall national cybersecurity strategy.

Please note that further analysis and consultation may be necessary to make a final decision based on our company’s specific requirements and capabilities.
