Abstract
Maritime ports play a pivotal role in the global economy, handling billions of tonnes of cargo annually. The security landscape of ports has evolved alongside their modernisation, which increasingly integrates technologies such as Information Technology (IT), Operational Technology (OT), Internet of Things (IoT), cloud computing, and digital data management. This growing digitalisation has, however, exposed ports to a rising number of cyber threats, as seen in recent incidents including the Port of Nagoya cyber attack, the DP World Australia incident, and Port of Seattle cyber attack. Cybersecurity now ranks among the top risks for ports, alongside piracy and terrorism, yet many ports remain underprepared. Every device, software, and network connection must be secured due to the highly complex and interconnected nature of port systems. According to a report by Lloyd’s of London, a single cyber attack on major ports in the Asia-Pacific could result in losses of up to US$110 billion.
Southeast Asia hosts some of the world’s busiest ports, including the Port of Singapore, Port of Tanjung Pelepas, and Belawan Port in Indonesia, all located along or near the Strait of Malacca, one of the busiest and most critical maritime chokepoints globally. Disruptions to these hubs would have severe consequences for the global maritime supply chain. While ports in the region are adopting advanced technologies to enhance efficiency and capacity, accelerating digitalisation also increases vulnerability to cyber threats. The diverse management structures and multiple operators across ports, combined with the absence of uniform security standards, exacerbate these vulnerabilities.
Given these challenges, there is a pressing need for systematic, harmonised regulatory frameworks and compliance mechanisms to strengthen port cybersecurity across Southeast Asia. Ensuring cyber resilience requires coordination between public authorities, private operators, and international standards. This paper seeks to provide recommendations for regulatory and policy readiness in major Southeast Asian ports, aiming to address cybersecurity gaps, improve preparedness, and safeguard the region’s critical maritime infrastructure.
