The rapid digitalization of the maritime industry has transformed operational efficiency and global supply chain connectivity but has also introduced significant cybersecurity challenges. This study explores the critical components of cybersecurity within maritime infrastructure, highlighting vulnerabilities in vessels, port systems, logistics networks, and cargo management platforms. It addresses the increasing prevalence of cyber threats such as ransomware, phishing, and GPS spoofing, and their potential impacts on operational safety, financial stability, and data integrity. Key strategies for mitigating these risks include implementing robust network security measures, encrypting sensitive data, developing comprehensive incident response plans, and fostering cybersecurity awareness through employee training. Furthermore, adherence to international compliance standards, such as the IMO’s cybersecurity guidelines, underscores the importance of a unified and proactive approach to managing cyber risks in maritime operations. Case studies, such as the NotPetya attack on Maersk, illustrate the real-world implications of cybersecurity breaches and the necessity for resilient frameworks. This research underscores the urgent need for the maritime sector to integrate advanced cybersecurity practices to safeguard critical infrastructure, maintain global trade continuity, and build a secure future for digital maritime operations.
