The shipping industry is increasingly vulnerable to cyber threats, including ransomware attacks, GPS spoofing, and supply chain disruptions. The intersection of IT and operational technology (OT) in modern shipping makes it a lucrative target for cybercriminals and state-sponsored actors. Key vulnerabilities exist in e-navigation systems, industrial control systems, and port management platforms, which can lead to navigation issues, operational downtime, and even environmental disasters. The shift towards digital-first shipping operations has introduced significant cybersecurity risks, including the use of IoT-enabled sensors and remote fleet management via cloud-based platforms. AI-driven threat detection is playing a growing role in maritime cybersecurity, enabling real-time monitoring of shipboard systems for anomalies. Zero trust architecture is being adopted to enforce strict access controls and continuous verification for all onboard systems. The industry must shift from reacting to attacks to proactively preventing them, with a combination of cutting-edge AI defenses, zero trust security principles, and robust collaboration across the industry.
