Artificial intelligence (AI) has become a key force in modern national defense, influencing how nations approach cybersecurity—particularly in the area of ​​critical infrastructure. AI has been used in cybersecurity for years, but the recent focus on generative AI has spurred further innovation and highlighted its security applications. Integrating AI into defense strategies is not only a technological advancement, but also a necessity to protect critical infrastructure and national security from evolving threats.

While there are concerns about how AI could be used to conduct cyber incidents, these risks underscore the importance of using AI for security benefits. This analysis focuses on the critical role of AI as a cybersecurity tool, with critical infrastructure being a prominent example of its application. While significant progress has been made, more work is needed to fully realize the potential of AI in securing national defense and critical infrastructure.

AI as a Cybersecurity Tool for National Defense

AI has impacted national defense cybersecurity by improving threat detection, automating responses, and enabling predictive capabilities. Its continuous learning allows defense systems to evolve with emerging threats while adapting algorithms to counter new attack vectors. One of AI’s key benefits is its ability to assess and prioritize threats based on their severity, helping defense teams allocate resources effectively.

To better illustrate the role of AI, consider two specific examples: AI-powered threat intelligence platforms that enable faster, more effective responses, and the integration of AI into critical infrastructure security management. Both highlight the importance of AI in creating a dynamic and resilient defense posture, driving innovation, and strengthening homeland security.

Detection and analysis of threats in networks
AI algorithms are excellent at identifying patterns and anomalies in massive amounts of data, making them ideal for detecting cyber threats in real time. By continuously analyzing network traffic, AI can pinpoint malicious activity that might go unnoticed by human analysts (or at least take up valuable human time), including zero-day vulnerabilities. This ability is crucial in defending against sophisticated and constantly evolving cyberattacks.

Automated response and mitigation for systems
AI-based systems can minimize damage and improve response times by autonomously responding to detected threats. Automated responses include isolating compromised systems, blocking suspicious IP addresses, and patching vulnerable systems. This automation is essential in national defense scenarios where every second counts. By reducing the need for human intervention, AI enables threats to be addressed more quickly and effectively—essential in high-stakes environments.

Behavior analysis and anomaly detection
AI systems use machine learning to understand typical behavior across networks and identify anomalies that could indicate a cyber threat. This ability is particularly useful in military contexts, where rapid detection of unusual activity can prevent insider threats and other major security breaches. AI’s ability to analyze and learn from large data sets means it can adapt to new threats and continually improve its detection capabilities.

Artificial Intelligence in Critical Infrastructure

Critical infrastructure includes energy, water, transportation, and communications—all of which are essential to national and public security. Protecting these sectors from cyber threats is essential because disruptions can have broad impacts. AI is increasingly being used across critical infrastructure sectors, with some applications directly targeting cybersecurity and others not directly related to cyber threats but with the potential to be used for security purposes. This is especially important because most critical infrastructure is privately owned, limiting direct government adoption of the technology. Selected examples of AI use in these sectors offer best practices that can be more broadly adopted to improve cybersecurity.

Energy
AI-powered predictive maintenance systems in the energy sector prevent outages by resolving potential issues before they develop. For example, the Tennessee Valley Authority implemented AI systems that monitor equipment health and predict failures, facilitating timely maintenance and preventing costly power outages.

Water
In the water sector, AI technology has proven valuable in monitoring and securing water distribution networks. For example, the city of Atlanta implemented an AI-based system that analyzes data from sensors throughout the water network to detect leaks and potential contamination. This proactive approach ensures a safe and reliable water supply by identifying problems before they develop.

Additionally, researchers at Florida A&M University and Florida State University are exploring the potential of AI to improve water quality in the state. Their work includes developing AI models that can predict harmful algal blooms, monitor water quality and optimize resource use. These initiatives aim to provide more accurate and timely information, ultimately leading to better water management and protection against pollution.

Transport
AI is making significant progress in the transportation sector, particularly in improving cybersecurity and operational efficiency at critical infrastructure locations. For example, the Port of Los Angeles has deployed AI to strengthen its cybersecurity posture. By analyzing network traffic and identifying anomalies, AI helps protect the port’s critical infrastructure from cyber threats, ensuring the smooth operation of this important hub for international trade.

In addition, GridMatrix has deployed AI software to improve operational efficiency and safety at the Port of Newark-Elizabeth Marine Terminal in New Jersey. This AI-based system analyzes traffic patterns, optimizes vehicle movements and reduces congestion, while also focusing on cybersecurity. The integration of AI in these ports underscores its essential role in securing critical infrastructure and streamlining the flow of goods and services.

Healthcare
In healthcare, AI is playing a key role in securing sensitive patient data and ensuring the integrity of medical devices—especially in light of recent widespread cyber incidents targeting healthcare systems. For example, Mayo Clinic uses AI-based systems to monitor network traffic for signs of cyber threats, effectively protecting both patient data and critical healthcare infrastructure. By detecting and responding to emerging threats, these systems help mitigate the risk of sophisticated cyberattacks on healthcare organizations.

Application

Integrating AI into cybersecurity efforts has had a profound impact on protecting critical infrastructure. Joint public-private sector initiatives, such as AI-powered threat intelligence sharing platforms, have enabled faster and more effective responses to cyber threats, demonstrating AI’s role in enhancing national defense. And programs such as the Federal Communications Commission’s U.S. Cyber ​​Trust Mark are designed to certify products that meet cybersecurity standards, contributing to a more secure technology landscape. With its continued ability to further enhance cybersecurity, AI remains key to addressing future challenges. Ongoing research, development, and strategic collaboration will be essential to realizing AI’s full potential to protect critical infrastructure and national security. The future holds promising opportunities for continued AI innovation and cybersecurity advancement.
