The maritime industry is facing increased cybersecurity risks due to pivotal environmental regulations that prioritize vessel efficiency. These regulations include the Energy Efficiency Design Index (EEDI) and the Energy Efficiency Existing Ship Index (EEXI) introduced by the International Maritime Organization (IMO) in 2011 and 2023, respectively. Additionally, the European Commission (EC) adopted Fit for 55 in 2021, aiming to reduce net greenhouse gas emissions by 55% by 2030. While these regulations aim to achieve environmental sustainability, they have inadvertently raised concerns about operational technology (OT) cybersecurity in the maritime industry.
The implementation of these efficiency measures requires vessels to make substantial investments in advanced technologies and sophisticated equipment to enhance efficiency, which in turn increases the risk of using OT in the maritime industry. Integrating these technologies with existing OT systems and real-time cloud-based monitoring presents a unique challenge to maritime cybersecurity, a field characterized by inherent vulnerabilities.
Just as the naval industry underwent a significant transformation in the late 1800s with the invention of steam propulsion technology, the maritime industry is now experiencing a shift towards greener technologies. Mariners had to adapt to the new technologies that came with unique challenges, similar to the current cybersecurity risks faced by the industry.
One of the factors that increase maritime cybersecurity risks is the vulnerability of legacy systems within OT networks. These systems, which encompass critical systems such as radar, electronic charts, cargo and engine monitoring, and automatic identification systems (AIS), often operate on outdated software and protocols, making them susceptible to cyberattacks. Replacing or upgrading these legacy systems should be considered within strategic planning and resource allocation, despite the high costs involved.
Authentication and access controls, which are crucial for cybersecurity, must be implemented appropriately within OT networks. Weak or shared passwords can facilitate unauthorized network access, increasing the risk of cyberattacks. Additionally, the inherent design limitations of many OT systems make it challenging for system administrators to detect security breaches, highlighting the need for more visibility and monitoring within these networks.
The integration of OT systems with cloud-based infrastructure, as required to achieve efficiency standards, expands the potential attack surface for cyber threats. Furthermore, with increased connectivity to shore-based systems, external networks, and cloud-based infrastructure, the cybersecurity risk escalates in vessels’ OT systems.
Supply chain attacks are also a significant concern in the maritime sector. Attackers can exploit vulnerabilities in third-party vendors or suppliers to gain entry into the systems of target organizations. Once access is obtained, they can plant malware or gain unauthorized access to a vessel’s systems.
The new environmental regulations have created additional risks for the maritime industry, including economic implications, operational challenges, legacy systems vulnerability, authentication and access control issues, the need for robust cybersecurity measures, and the need for third-party vetting and monitoring.
Adherence to the new regulatory environment requires considerable investments in advanced technology and equipment, as well as the integration of these technologies with existing OT systems. This results in high upfront costs and ongoing maintenance expenses.
The necessity for real-time cloud-based monitoring and data transmission adds complexity to maritime operations. The increased integration between onboard OT and external systems also increases vulnerability to cyberattacks, which can lead to severe operational disruptions.
Legacy systems within OT networks, which often have outdated designs and protocols, are particularly vulnerable to cyberattacks. However, replacing or upgrading them poses a daunting task due to the high costs involved and their critical nature.
The underimplementation of robust authentication and access controls in OT networks exacerbates cybersecurity threats, including unauthorized access and network breaches that can impact critical operations and data integrity.
To combat the augmented cybersecurity risks, maritime companies must implement robust cybersecurity measures. These measures may include intrusion detection systems, regular system updates, enhanced access controls, and network segmentation. However, these measures add to the operational complexity and financial burden faced by maritime companies.
Mitigating supply chain attacks requires thorough vetting and monitoring of third-party vendors. This adds complexity to procurement processes and necessitates ongoing monitoring to ensure compliance with cybersecurity best practices.
Amid escalating cybersecurity threats and critical OT systems, the maritime industry and its partners face profound challenges. Immediate investments in cutting-edge technologies, system upgrades, stringent access controls, network segmentation, and rigorous vendor vetting are essential. Delaying action can have significant and potentially catastrophic consequences. By acting swiftly and confidently, the maritime industry can protect itself, secure its resilience, and fortify itself against future threats. The industry’s future rests on resolute action taken today.
