Time is of the essence to address a multifaceted problem to protect the United States from individual actors, nefarious groups, or rogue nation-states. We have seen three industrial revolutions that have transformed our modern society. With each of these advancements from the steam engine, the age of science and mass production, and the rise of digital technology—the world around us has fundamentally changed. Technology is moving so quickly and those in the arena of homeland security must be equally prepared to evolve with a versatile adversary to combat threats and protect our nation. Emerging technologies will play a large role and looking into the future to create problem- solving strategies and deploy tactical responses is a necessity.
Question:
Looking toward the next decade for DHS, what should their organizational priorities and mission(s) areas be?
The Department of Homeland Security (DHS) was established in response to the evolving threats of the 21st century, primarily after the tragic events of 9/11. Its core mission has since been to protect the United States from a wide range of threats, including terrorism, natural disasters, cyberattacks, and other forms of domestic and international harm. As we move into the next decade, the nature of these threats is shifting in unprecedented ways. With each passing year, technological advancements, globalization, and geopolitical realignments bring new challenges that necessitate rapid adaptation by DHS. The past three industrial revolutions have reshaped the fabric of society, and the fourth industrial revolution — characterized by artificial intelligence, biotechnology, cyber technologies, and automation — will transform the threat landscape and require equally transformative responses.
To address the question of what the DHS’s organizational priorities and mission areas should be in the next decade, this essay argues that the department must adapt to a rapidly evolving security environment driven by technological change. Specifically, the DHS should focus on five key priority areas: cybersecurity, counterterrorism and domestic extremism, border security and immigration reform, disaster preparedness and resilience, and the integration of artificial intelligence and emerging technologies into homeland security. These priorities, informed by the lessons of past revolutions and the current trajectory of global threats, will allow the DHS to effectively protect the United States against individual actors, nefarious groups, and rogue nation-states in the years to come.
The most pressing challenge facing DHS in the next decade will be the need to address the growing threat of cyberattacks against the nation’s critical infrastructure, private sector, and governmental agencies. As society becomes increasingly dependent on digital networks and data systems, cybersecurity has become the backbone of national security. A 2022 report by the World Economic Forum identified cyberattacks as one of the top global risks, a sentiment echoed by U.S. national security leaders. The vulnerability of critical infrastructure, such as power grids, water supplies, transportation systems, and financial institutions, to cyberattacks from state and non-state actors alike presents a significant challenge. In recent years, ransomware attacks on major corporations like Colonial Pipeline have highlighted the devastating potential of cyberattacks to disrupt everyday life and the economy. DHS must ensure that it is capable of responding to and preventing such incidents on a broader scale.
The establishment of the Cybersecurity and Infrastructure Security Agency (CISA) within DHS in 2018 marked an important step in addressing these issues, but its scope and capabilities must be expanded. In the next decade, CISA will need to develop more robust public-private partnerships, as much of the nation’s critical infrastructure is owned and operated by private entities. Collaborative defense frameworks will need to be enhanced through real-time information sharing, joint security protocols, and collaborative threat analysis with major industries. DHS should invest heavily in improving the nation's cybersecurity posture by funding research into more advanced encryption technologies, secure communications platforms, and incident response capabilities. As cyber threats increasingly originate from sophisticated state-sponsored actors such as China and Russia, this will require coordinated efforts across all levels of government and the private sector.
The "asymmetry" of cyber warfare, as described in international security literature, suggests that smaller, less resourced adversaries can cause disproportionate harm to larger, more powerful nations through cyberattacks. This means that while the U.S. might have the most advanced military, cyberattacks can provide adversaries with a low-cost, high-impact weapon, amplifying the need for DHS to prioritize robust cybersecurity defenses. For instance, the SolarWinds cyberattack, in which Russian hackers infiltrated U.S. government systems, demonstrates the profound implications of failing to adequately secure federal networks. Going forward, the DHS should work toward creating a "zero trust" architecture across government agencies, ensuring that any unauthorized access to sensitive information is immediately flagged and mitigated. In summary, DHS must prioritize strengthening cybersecurity defenses to protect critical infrastructure and government systems, preparing for more advanced and persistent threats from state-sponsored actors and criminal networks.
As traditional foreign terrorism remains a threat, the rise of domestic extremism and radicalization presents an evolving challenge for DHS. While foreign terrorist organizations such as al-Qaeda and ISIS continue to pose a threat, there has been a notable shift in the nature of terrorism in recent years. Domestic terrorism, particularly from white supremacists, anti-government militias, and other radicalized groups, has surged to the forefront of homeland security concerns. The 2021 storming of the U.S. Capitol on January 6th marked a turning point, demonstrating that domestic actors motivated by disinformation, conspiracy theories, and extremist ideologies could orchestrate large-scale attacks. This growing trend has been exacerbated by online radicalization and the proliferation of extremist content on social media platforms.
DHS will need to strengthen its counterterrorism efforts by focusing more on the prevention of domestic extremism, which will involve a multi-pronged approach. First, DHS should enhance its intelligence capabilities to better monitor extremist networks and prevent attacks. This may involve greater coordination with the FBI, local law enforcement, and technology companies to track the activities of radicalized individuals online. Second, counter-extremism initiatives will need to expand their focus on de-radicalization and early intervention programs. DHS should work with community organizations, mental health professionals, and educational institutions to identify and assist individuals at risk of radicalization.
Theories of radicalization, such as Marc Sageman’s “Leaderless Jihad” concept, suggest that decentralized networks of self-radicalized individuals can pose as significant a threat as well-organized terror cells. This insight implies that a key priority for DHS must be the monitoring of online spaces where radicalization takes place and where lone actors may be planning attacks without direct ties to terrorist organizations. For instance, the 2018 Tree of Life synagogue shooting in Pittsburgh, committed by a lone actor radicalized through online platforms, exemplifies the growing risk of domestic terrorism. DHS needs to adopt more comprehensive monitoring of extremist activity online to prevent such acts of violence before they materialize. In conclusion, addressing domestic extremism and continuing efforts in counterterrorism must be a top priority for DHS. The agency must adapt its strategies to account for the increasingly decentralized and homegrown nature of modern terrorism, particularly through online radicalization.
With increasing political tension over immigration, DHS must continue to develop comprehensive border security measures while also reforming immigration policies to address both humanitarian and security concerns. Border security has long been one of the core responsibilities of DHS, particularly through agencies such as U.S. Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE). The southern border of the United States remains a focal point for immigration and drug trafficking, but the growing complexity of migration patterns — driven by economic instability, climate change, and political unrest in Central America and elsewhere — will require DHS to adopt a more nuanced approach to border management. Securing the border does not just involve building physical barriers but rather investing in technology, such as drones, sensors, and biometric systems, to monitor and manage the flow of people and goods efficiently.
DHS must also prioritize comprehensive immigration reform, focusing on creating legal pathways for immigration and addressing the root causes of migration, such as poverty, corruption, and violence in migrants’ home countries. The agency should work closely with other federal entities, such as the Department of State, to develop policies that promote stability in regions like Central America, which are the source of much of the migration pressure on the U.S. southern border. At the same time, immigration enforcement must be conducted in a manner that respects human rights and ensures the humane treatment of migrants.
According to deterrence theory, strict border enforcement alone is insufficient to stop illegal immigration if the root causes of migration (push factors) are not addressed. Research suggests that migration deterrence is more successful when coupled with legal avenues for migration and efforts to improve conditions in migrants’ home countries. For instance, the Migrant Protection Protocols (commonly referred to as the "Remain in Mexico" policy) created significant controversy and led to poor humanitarian outcomes. In contrast, efforts to provide legal work visas and improve infrastructure at legal ports of entry have demonstrated more effective and humane ways to manage migration.
Thus, DHS should shift towards a strategy that combines the use of advanced technology for border security with policies that address the humanitarian aspects of immigration. This approach will ensure a secure and humane system of border control that meets the challenges of the next decade.
In an era of increasingly frequent and severe natural disasters, DHS must enhance its focus on disaster preparedness and resilience, especially in light of climate change. The effects of climate change, such as more intense hurricanes, wildfires, floods, and droughts, have escalated the demand for disaster response capabilities. As climate-related disasters become more frequent, DHS, through the Federal Emergency Management Agency (FEMA), will need to bolster its efforts in both disaster preparedness and resilience-building. This involves not only responding to disasters but also investing in infrastructure that can withstand extreme weather events and in communities’ capacity to recover quickly.
In the next decade, DHS should prioritize pre-disaster mitigation efforts, such as investing in climate-resilient infrastructure and community preparedness programs. The agency must also develop stronger partnerships with local governments, non-profit organizations, and the private sector to improve disaster response coordination. DHS should push for the integration of emerging technologies, such as artificial intelligence and geospatial data analytics, to improve predictive modeling for disasters and optimize the deployment of resources.
The concept of "resilience" in disaster management emphasizes the ability of systems and communities to withstand and recover from disruptions. This approach, rooted in ecological and systems theory, suggests that DHS must not only focus on immediate disaster response but also on enhancing the long-term resilience of vulnerable populations and infrastructures. For instance, the devastating impact of Hurricane Maria on Puerto Rico in 2017 revealed significant gaps in disaster preparedness and response. FEMA's slow response and lack of resources underscored the need for better coordination and pre-disaster planning. Going forward, DHS must ensure that similar failures are avoided by investing in infrastructure that can better withstand the impact of extreme weather events. In conclusion, DHS must take a proactive approach to disaster preparedness and resilience, focusing on building the capacity of communities to adapt to and recover from the effects of climate change.
As technology rapidly advances, DHS must prioritize the integration of artificial intelligence (AI) and other emerging technologies into its operations to stay ahead of evolving threats. The fourth industrial revolution has brought about transformative technologies such as AI, machine learning, and autonomous systems that have the potential to revolutionize homeland security. In the next decade, DHS must leverage these technologies to enhance its capabilities across a range of mission areas, including cybersecurity, border security, and disaster response. AI can be used for predictive analytics, enabling DHS to anticipate threats before they materialize. For example, machine learning algorithms can analyze vast amounts of data to identify patterns that indicate potential terrorist activity or cybersecurity breaches. Autonomous drones and robotic systems can assist with border surveillance and disaster recovery operations, providing real-time intelligence and reducing the risk to human personnel.
However, the integration of AI and emerging technologies into DHS operations will require careful management to avoid unintended consequences. Issues such as bias in AI algorithms, privacy concerns, and the risk of over-reliance on technology must be addressed. DHS will need to establish clear ethical guidelines for the use of these technologies and invest in human oversight to ensure that AI systems are used responsibly and effectively.
The "technological determinism" perspective suggests that technological advancements drive social and political change, often in ways that are unpredictable. This theory underscores the importance of DHS staying ahead of the curve in technological innovation while remaining vigilant about the potential risks and ethical implications of relying too heavily on AI-driven systems. For instance, the use of AI-powered facial recognition technology by CBP at U.S. airports has been both praised for improving efficiency and criticized for its potential to infringe on privacy rights. As DHS continues to adopt such technologies, it must strike a balance between security and civil liberties, ensuring that the use of AI does not lead to discrimination or violations of individual rights. In summary, DHS must prioritize the integration of AI and other emerging technologies to enhance its capabilities, while also ensuring that these technologies are used ethically and responsibly.
As the world moves into the next decade, DHS faces an increasingly complex and multifaceted threat landscape driven by rapid technological advancement, domestic extremism, climate change, and evolving geopolitical tensions. In response, DHS’s organizational priorities must adapt to meet these challenges head-on. By focusing on strengthening cybersecurity, countering domestic extremism, reforming border security and immigration policies, enhancing disaster preparedness, and integrating emerging technologies like AI, DHS can better protect the United States from the full spectrum of threats it faces. The lessons of the past industrial revolutions teach us that those who fail to adapt to technological and societal change are left vulnerable. As such, DHS must evolve in its mission and capabilities to stay ahead of adversaries and protect the American people in the next decade.
