The increasing sophistication and frequency of cyberattacks pose a critical risk to the security of essential infrastructure systems, such as energy grids, water systems, and transportation networks. Real-time threat monitoring has emerged as a crucial component of modern cybersecurity strategies, enabling proactive identification and mitigation of vulnerabilities. InfraGuard, a collaborative initiative between the FBI and private sector stakeholders, has played a pivotal role in strengthening the cybersecurity posture of critical infrastructure sectors. This review explores the current state of real-time threat monitoring, evaluates the contributions of InfraGuard, and highlights emerging technologies and best practices for securing critical infrastructure against evolving cyber threats.With cyber threats growing in both sophistication and frequency, the need for real-time threat monitoring and rapid response mechanisms has become paramount. InfraGuard, a public-private partnership initiated by the FBI, plays a pivotal role in enhancing the cybersecurity of critical infrastructure through collaborative efforts among government agencies, private-sector companies, and cybersecurity professionals. This paper explores the role of InfraGuard in real-time threat monitoring for critical infrastructure, highlighting its impact on proactive threat detection, information sharing, and collaborative defense strategies. We also examine the challenges, opportunities, and future directions for InfraGuard in addressing the evolving landscape of cybersecurity threats.
