Critical infrastructure systems such as energy grids, water treatment plants, transportation networks, and healthcare facilities are vital to the functioning of modern society. As these infrastructures become increasingly interconnected and reliant on digital technologies, they also become more vulnerable to cyberattacks, physical threats, and hybrid attacks. The growing sophistication and frequency of these threats pose significant risks to public safety, national security, and economic stability. In response to these challenges, this paper proposes "Infraguard," a comprehensive, real-time threat detection and automated response system designed to enhance the security and resilience of critical infrastructure.This paper explores the architecture and operational framework of Infraguard, detailing its core components such as real-time monitoring, threat intelligence sharing, cloud-based data processing, and automated decision-making. Additionally, it discusses the challenges in deploying such a system, including the management of false positives, privacy concerns, and integration with legacy infrastructure. Finally, the paper highlights the potential of Infraguard to strengthen the security posture of critical infrastructure by providing a proactive, agile, and scalable solution to the evolving landscape of threats.The introduction of Infraguard marks a significant advancement in the field of critical infrastructure protection, offering a robust defense against both cyber and physical threats.
