Why Cyber Security Matters at Sea

Maritime cyber security is about more than just protecting systems, networks, and data; it is about ensuring the security and continuity of maritime operations and anticipating and mitigating cyber security threats to prevent the compromise of sensitive and personal information for VIP stakeholders.  

This article will look at the various aspects of maritime cyber security and provide practical insights and strategies for protecting maritime assets. 

Understanding Maritime Cyber Security  

From navigation and communication systems to engine controls and onboard entertainment, virtually every aspect of modern vessel operations relies on digital technology. Any vulnerability in these systems can be exploited by cyber attackers, posing a significant risk to the vessel, its crew, and its passengers. We've identified several risks specifically affecting the maritime industry, including:

1. Increasing digitalisation and the introduction of faster connectivity, such as Starlink, has expanded the attack surface and made vessels more vulnerable to cyber threats. 
2. Many vessels still use outdated technology and systems that are costly to upgrade and do not easily integrate with modern cyber security measures or are not easily detectable, leading to security gaps. 
3. Multiple third parties (e.g., cargo operators, port authorities, and other technology providers) are involved, increasing the risk of vulnerabilities through interdependent systems or the need for external remote access to support systems. In some cases, third parties are left to work unsupervised. Alternatively, the crew could be required to supervise their activities, preventing them from focussing on other tasks.
4. Vessels frequently communicate with multiple suppliers, vendors, authorities, and contractors. The contacts they interact with often change, making it challenging to verify the legitimacy of incoming emails and communications.

To effectively manage the cyber risks that can occur at sea, captains, owners, and fleet managers must first understand the potential consequences of a successful attack. Apart from the immediate disruption to operations, a cyber breach can have extreme consequences, such as: 

• Compromised systems: A malicious actor could gain unauthorised access to and take remote control of critical systems.  

• Data theft: A breach of sensitive data or financial records that could lead to identity theft, fraud, blackmail, vessel damage and significant financial costs.

• Reputational damage: A cyber-attack that damages the reputation of the yacht owner, captain, fleet manager, or charter company. 
  

• Legal and regulatory consequences: Failure to protect against cyber threats can lead to legal implications, fines, and regulatory compliance issues, particularly with the IMO’s strict maritime cyber security regulations. 
  
  
• Financial implications: Any of the above consequences can have far-reaching financial implications caused by damage to the vessel, its systems, or other property, cancelled charters, and regulatory fines.

A Strategic Approach to Maritime Cyber Security 

To effectively protect your environment against cyber threats, as attacks become more sophisticated and more difficult to detect, yacht owners and operators must implement a solid cyber security strategy that includes a series of proactive measures to identify, mitigate, and respond to potential cyber risks. Below is an overview of the key components of such a strategy: 

1. Risk Assessment:  
   Regular checks are important to identify potential vulnerabilities and threats to the systems and data on board. Assessments that consider the specific characteristics of the vessels, the types of technology on board and the potential impact of a cyber-attack should be carried out regularly to maintain the security and safety of systems and data in the face of potential cyber threats. 
   
   
2. Cyber Security Awareness Training: 
   Educating crew members and passengers on cyber security best practices is key to maintaining a safe environment on board and promoting a culture of security awareness.
    
3. Password Management:  
   Implementing strong password policies and practices and using the right password management tools can help store and manage passwords securely, reducing the risk of unauthorised access due to weak or compromised credentials.
   
   
4. Network Segmentation: 
   Network segmentation helps to divide the onboard network into separate sections based on functions or sensitivity levels. This helps vessel operators contain the spread of malware and minimise the risk of unauthorised access to their systems.
     
   
5. Access Control: 
   Strict access controls restrict unauthorised access to systems and data, just as authentication mechanisms ensure that only authorised persons can access sensitive information or control internal systems. Implementing ‘least privilege access’, where users are given the minimum levels of access or permissions needed to perform their job, is recommended.
     
6. Continuous Monitoring and Improvement: 
   Continuous monitoring and reassessment of your security, along with closing identified security gaps are key to detecting and responding to cyber threats in real-time. Vessel operators should have the right systems in place to monitor network traffic for signs of suspicious activity and automatically block or quarantine malicious traffic.  

The Road Ahead  

Maritime professionals must prioritise cyber security as an integral component of your risk management strategy. Just as there would be investment in advanced navigational equipment, safety protocols, and crew training to reduce physical risks at sea, there must be investment in strong cyber security measures to protect your vessels and crew from cyber threats. Effective maritime cyber security requires a layered approach that factors in both technical vulnerabilities and human factors. By taking a proactive stance against cyber threats and adopting a strategic approach to cyber security, vessel operators can sail the digital seas with confidence and peace of mind.
