  • Protection of sensitive data: Marine organisations deal with sensitive data, including personal and financial information, which can be stolen or misused in a cyber attack.
  • Increase in remote work: With an increase in remote work, there is an increased risk of cyber threats like phishing and ransomware attacks on employees working from home, which can ultimately affect the organisation.
  • Dependence on technology: Marine organisations are becoming increasingly reliant on operational technology for communication, navigation, and operations, making it essential to secure these industrial control systems against cyber threats.

Threats to Marine Cybersecurity

Threats to marine cybersecurity can be significant risks to both the safety and security of ships, ports, and the global maritime transportation network. Here are some of the significant threats to marine cybersecurity:

  • Cyber attacks on ship navigation systems: Cybercriminals can target ship navigation systems, including GPS and electronic chart display and information systems (ECDIS), to cause confusion, alter courses, or even cause ship collisions.
  • Cyber attacks on shipboard control systems: Hackers can also target shipboard control systems, including engine and propulsion control systems, which can potentially cause a loss of control and physical damage to the vessel.
  • Cyber attacks on port control systems: Cybercriminals can target port control systems to disrupt port operations, cause financial damage, or steal sensitive information, including cargo manifests and shipping schedules.
  • Cyber attacks on maritime communication systems: Cybercriminals can intercept and manipulate communications between ships and ports, potentially causing misunderstandings, disrupting operations, or stealing sensitive information.
  • Phishing and social engineering attacks: Cybercriminals can use social engineering tactics, like phishing emails and fake websites, to trick crew members and shore-based personnel into divulging sensitive information or even installing malware on shipboard or port computer systems.
  • Ransomware attacks: Cybercriminals can use ransomware to encrypt critical shipboard or port computer systems and demand payment to restore access, potentially causing significant operational and financial damage.
  • Insider threats: Insiders with authorised access to shipboard or port computer systems can intentionally or unintentionally cause harm by stealing sensitive information, introducing malware, or disrupting operations.

Best Practices for Maritime Cybersecurity: Maritime Cyber Risk Management

How can maritime organisations safeguard shipping-related operational technology assets from cyber risks?

  1. Conduct a Cybersecurity Risk Assessment: Identify the emerging cyber vulnerabilities and threats to the marine vessel or port systems. Determine the potential impact of the cyberattacks and prioritise the risk mitigation efforts.
  2. Cybersecurity Training and Awareness: Train the crew members, staff, and contractors on cybersecurity risks, threats, and best practices. Foster a cybersecurity culture and encourage the reporting of security incidents.
  3. Cyber Hygiene Measures: Implement basic cybersecurity measures, such as password policies, software updates, and patch management. Limit removable media and external devices that could introduce malware or unauthorised access to the cyber systems.
  4. Cybersecurity Incident Response: Develop an incident response plan and train the crew members and staff on the response procedures. Establish communication protocols with the relevant authorities and stakeholders in the event of a cybersecurity incident.
  5. Access Control and Network Segmentation: Limit the access rights to the vessel or port systems to authorised personnel only. Use network segmentation to isolate critical systems and reduce the attack surface.
  6. Cybersecurity Monitoring and Detection: Deploy cybersecurity monitoring tools, like intrusion detection and prevention systems and Security Information and Event Management systems. Monitor the network traffic and system logs for strange activities and indicators of compromise.
  7. Encryption and Data Protection Technologies: Implement encryption and data protection technologies to safeguard sensitive data, like personal data, financial data, and intellectual property. Use secure communication protocols, like SSL/TLS and VPNs, to protect the data in transit.
  8. Compliance with Regulations and Standards: Adhere to the international and national regulations and standards for cybersecurity in the maritime industry, such as the International Maritime Organization (IMO) guidelines, International Ship and Port Facility Security (ISPS) Code, and International Association of Classification Societies (IACS) requirements.
