Maritime security is not a convenience but a necessity.
The ocean is not only a source of life but also of wealth. It plays a vital role in the world economy as it facilitates international trade, provides jobs and income, and supports innovation and development. Sea trade is the movement of goods and services by sea using ships, ports, and other maritime infrastructure. It is the backbone of international trade, accounting for more than 90% of the global trade volume. Sea trade enables countries to access foreign markets, diversify exports, and import essential goods at lower costs. It also contributes to regional integration and cooperation as well as to the development of coastal and island states.
Rising Cyber Threats in the Maritime Industry
Cyberattacks have become a widespread threat in the modern digital era. This threat affects not only the tech industry but also other sectors, including the maritime industry. There are two types of technologies employed in the ships, namely IT and OT.
IT stands for information technology and covers the spectrum of technologies for information processing, including software, hardware, and communication technologies. IT devices on merchant ships include computers, laptops, tablets, smartphones, routers, switches, servers, printers, and scanners. IT devices are used for various purposes, such as data storage, data analysis, data transmission, office applications, email, internet access, and entertainment.
OT stands for operational technology, and refers to devices, sensors, software, and associated networking that monitor and control onboard systems. OT devices on merchant ships include engines, generators, pumps, valves, sensors, actuators, controllers, alarms, navigation systems, and communication systems. OT devices are used for various purposes, such as propulsion, steering, stability, cargo handling, safety, and emergency response.
IT and OT devices on merchant ships have similarities and differences. Both types of devices use digital technologies and communicate with each other through networks. Both types of devices can be vulnerable to cyber threats, such as malware, hacking, denial-of-service attacks, and data breaches. Both types of devices require regular maintenance and updates to ensure optimal performance and security.
However, IT and OT devices on merchant ships also exhibit significant differences. IT devices are designed for data processing and information exchange, whereas OT devices are designed for physical monitoring and control. IT devices are usually standardised and interchangeable, whereas OT devices are customised and specific to each ship. IT devices are usually updated frequently and remotely, whereas OT devices are updated infrequently and locally.
The differences between IT and OT devices on merchant ships have implications for cybersecurity and safety management. IT devices can be more easily protected using firewalls, antivirus software, and encryption and authentication methods. OT devices can be more difficult to protect because they may not support these methods or may have compatibility issues. OT devices can also have more severe consequences if compromised, because they can affect the physical safety of the ship, crew, and environment.
– GPS spoofing or jamming attacks on ships or navigation systems can alter or block the signals used for positioning and timing. This can cause ships to deviate from their intended course or to collide with other vessels or obstacles. For instance, in June 2017, several ships in the Black Sea reported that their GPS systems were located near Russian airports.
– Cyberattacks on shipboard systems or equipment, such as propulsion, steering, communication, and cargo handling. This can compromise the safety and performance of a ship and its crew. For example, in July 2018, a US Navy destroyer was reportedly hacked by Chinese hackers who stole classified information on its missile system.
Therefore, it is important for ship owners, managers, and operators to understand the characteristics of IT and OT devices on merchant ships and implement appropriate measures to ensure cyber resilience.
A hacker who manages to infiltrate a merchant ship’s IT and OT systems, can cause chaos on board, and potentially result in significant financial losses. This is now an actual risk in the maritime sector.
As alarming as this may sound, it is essential to understand that there are ways to defend against these cyber threats. One such approach is ethical hacking, which involves conducting simulated cyberattacks to identify vulnerabilities before malicious hackers can exploit them.
Current Cybersecurity Landscape in the Maritime Industry
Understanding Cyber Security Risks in the Maritime Sector- Merchant ships are increasingly reliant on cyber physical systems which integrate physical components such as engines and steering mechanisms with digital technology for automation and control. These systems form the nerve centre of modern vessels but also present attractive targets for cyber attackers because of their critical role in navigation and ship operations. The interconnected nature of these systems can lead to cascading effects in the event of a cyber breach, potentially endangering a ship’s safety, cargo, and crew.
How Maritime Organizations Manage Cybersecurity Risks- To combat these risks, maritime organisations have turned to comprehensive cybersecurity frameworks, such as the NIST Cybersecurity Framework (CSF). This framework offers a structured approach for managing and mitigating cybersecurity risks across five key functions.
-Identify: Cataloguing assets and systems on board.
-Protect: Implementing safeguards to ensure delivery of critical services.
-Detect: Developing capabilities to identify cybersecurity events.
-Response: Formulating action plans for incident responses.
-Recover: Restoring impaired services and improving post-event quality
By applying the NIST CSF, maritime organisations can align their cybersecurity practices with industry standards, ensuring a heightened security posture.
Understanding Potential Cyber Threats- In parallel, understanding sophisticated cyber threats requires in-depth knowledge of the potential attack vectors. For instance, the MITRE ATT&CK Threat Model is provides a detailed matrix of tactics and techniques used by threat actors. For maritime security teams, this model aids in pre-empting attacker behaviours and securing IT and OT assets against:
-Intrusion tactics, such as spear-phishing or exploiting public-facing applications.
-Techniques designed to evade detection and maintain persistence within shipboard systems.
-Actions targeting specific control system components or seeking to manipulate sensor data.
-By integrating knowledge gleaned from MITRE ATT&CK with robust frameworks, such as NIST CSF, merchant ships can fortify their defences against the evolving landscape of cyber threats.
Securing Merchant Ships: Industry Standards and Best Practices
Protecting the vast network of merchant vessels navigating the vast seas requires a comprehensive approach to cybersecurity, adherence to rigorous industry standards, and employment of advanced risk assessment tools. Among these protective measures, the International Maritime Organization’s (IMO) guidelines on cyber risk management are at the forefront, offering ship operators a robust framework for identifying and mitigating cyber threats.
Industry Standards
International Maritime Organization (IMO) Guidelines: These are a set of recommended practices that help maritime organisations manage and reduce cyber risk. The guidelines emphasise the importance of leadership, integration into existing risk management processes, and continuous improvement. They advocate a cyber risk management strategy that is specific to the nuances of maritime operations.
Risk Assessment Tools
-Cybersecurity Frameworks: These tools assist in aligning security practices with business requirements, risk tolerances, and resources on merchant ships. Adopting such frameworks facilitates the identification of current security postures and planning for the desired outcomes.
-Methodologies: Comprehensive methodologies often include both automated vulnerability scanning to uncover potential weaknesses and manual penetration testing to simulate attacks on shipboard systems. These tools are vital in creating a clear picture of potential vulnerabilities within the maritime cyber infrastructure.
Industrial Control Systems (ICS) Infrastructure Security
A particular point of concern in securing merchant ships is safeguarding the ICS infrastructure.
–Industrial Control Systems (ICS): These systems control engines, steering gears, ballast systems, among others. Ensuring their security is paramount as they are linked to the safe operation of ships. Protective measures include network segmentation, robust access control, and regular system update. By adhering to established standards and utilising proven risk assessment methodologies, the maritime sector can fortify its defence against cyber threats. A special focus on ICS infrastructure acknowledges its critical role in ensuring not only digital safety, but also physical operational integrity aboard ships worldwide.
Identifying and Assessing Cyber Risks on Merchant Ships- To effectively safeguard merchant ships from cyber threats, a rigorous and layered approach to risk assessment is required. Risk assessment methods play a pivotal role in the defence strategy of the maritime industry against cyber-attacks. There are several approaches to conducting comprehensive assessments.
Automated Vulnerability Scanning-This method employs software tools to systematically check the systems for known security issues. Vulnerability scanning allows for quick identification of flaws that can be exploited by attackers.
Manual Penetration Testing- Sometimes referred to as ethical hacking, penetration testing involves simulating cyber-attacks to identify weak points in a system’s defence. Unlike automated tools, manual testing can uncover subtle vulnerabilities that require human intuition and experience for detection.
Expert-Led Audits
Engaging external security professionals provides an unbiased evaluation of the shipboard systems. These experts provide fresh perspectives and specialised knowledge that can reveal critical insights into the security posture of maritime operations.
Illustrative case studies have shed light on the effectiveness of combining these methods.
-A leading container carrier implemented regular vulnerability scans, followed by targeted penetration tests conducted by an external cybersecurity firm. Engagement uncovered previously undetected network vulnerabilities, leading to fortified network defences.
-In another instance, a cruise line hired cybersecurity consultants to discover that their ICS systems were accessible via the Internet without adequate protection. This finding prompted an overhaul of security protocols and implementation of stricter access controls.
By integrating these risk assessment methods, the maritime industry can better understand cyber vulnerabilities and reinforce their defence against evolving threats. The next step involves translating this understanding into actionable cybersecurity controls and measures to protect vital shipboard systems.
Implementing Effective Cybersecurity Controls and Measures
Implementing robust cybersecurity controls is crucial for protecting merchant ships from cyber threats. The key principles and measures to consider are as follows.
Principle of Least Privilege- The principle of least privilege mandates that access to sensitive data and operations should be restricted, with personnel granted only the minimum level of access necessary for their job functions. This helps minimise the potential damage caused by insider threats or compromised accounts.
Defence-in-Depth- Defence-in-depth is a multilayered approach to security that ensures that, if one security control fails, others are in place to thwart potential breaches. This approach includes:
-Network segmentation: The ship’s network is divided into numerous segments, each with its own protective measures. Network segmentation can limit the spread of an attack, effectively containing potential breaches and minimising their impact on critical ship systems.
-Perimeter security: Firewalls, intrusion detection systems, and other security measures are implemented at the network perimeter to prevent unauthorised access.
-Endpoint Protection: Installing antivirus software, conducting regular patch management, and implementing device encryption to secure endpoints such as computers and mobile devices.
-Data Encryption: Encrypting sensitive data at rest and in transit to ensure confidentiality, even if it falls into the wrong hands.
-Security Awareness Training: Educating crew members about common cyber threats, phishing techniques, and best practices for safe online behaviour.
-Multi-Factor Authentication (MFA): Authentication mechanisms also play a pivotal role in preventing unauthorised access to sensitive maritime data. The adoption of multi-factor authentication (MFA) can significantly enhance security. MFA requires users to provide at least two forms of identification before granting access, thereby adding an extra layer of protection against cyber-attacks.
By implementing the above controls and measures, merchant ships can bolster their cyber resilience and ensure the safety of their crew, cargo, and operations.
Regular Training and Awareness Programs for Ship Crew
Human elements have a significant role in maritime cybersecurity. Regardless of the robustness of the security measures, if the ship crew is not well versed with cybersecurity training, the ship remains vulnerable to attacks. Emphasising ongoing training and education initiatives is crucial for fostering a cyber-secure culture among seafarers. With the rapid evolution of technology, it is critical to stay updated on the latest threats and defence strategies. The training modules cover a range of topics:
-Phishing Awareness: Phishing is one of the most common tactics employed by cybercriminals. Seafarers must be trained to identify and report suspicious emails or messages that could be phishing attempts.
-Incident Response Procedures: The crew should be aware of the steps to take in the case of a cyber incident, including who to report to, how to contain the threat, and how to document it for further investigation.
Such initiatives can transform seafarers from potential security vulnerabilities to first-line defenders against cyber threats. By promoting an environment in which every crew member understands their role in maintaining cybersecurity on board, we can significantly enhance the resilience of merchant ships to cyber-attacks.
Ethical Hacking: Strengthening Cyber Defences through Responsible Vulnerability Assessment
Ethical hacking plays a pivotal role in fortifying the cybersecurity of merchant ships. Ethical hacking involves authorised cybersecurity experts known as white-hat hackers, who employ the same tactics as malicious hackers to evaluate and assess the security of IT and OT systems. In the maritime industry, these specialists simulate cyberattacks under controlled conditions to identify weaknesses before adversaries can exploit them.
