Top Cyber Security Risks And Innovative Solutions in Maritime

October 29, 2020 MARITIME CYBER SECURITY

Anastasios Arampatzis reports for Tripwire.com in its official website about the biggest challenges and best practices to mitigate risks in maritime cybersecurity.

Lets look at the essential factors that are crucial in strengthening the cybersecurity of Maritime Industry.

Maritime industry a target for cyber attackers

With more than 90% of the world’s trade being carried by shipping, according to the United Nations’ International Maritime Organization, the maritime industry is an attractive target for cyber attackers.

The European Union has recognized the importance of the maritime sector to the European and global economy and has included shipping in the Network and Information Systems (NIS) Directive, which deals with the protection from cyber threats of national critical infrastructure.

Ships rely on information and technology

Ships are increasingly using systems that rely on digitalization, integration, and automation, which call for cyber risk management on board.

The convergence of information technology (IT) and operational technology (OT) onboard ships and their connection to the Internet creates an increased attack surface that needs to be addressed.

Challenges in Maritime Cybersecurity

The evolution of digital and communications technology has allowed the integration of these two worlds, IT and OT.

The IT world includes systems in offices, ports, and oil rigs, OT is used for a multitude of purposes such as controlling engines and associated systems, cargo management, navigational systems, administration, etc.

Adjunct Professor at the Hellenic American University says, “Maritime industry, especially through vessels digitalization and with the numerous different Operational Technology devices deployed, creates a digital landscape previously unknown to a big extent due to the specific hardware and software being used. New security risks will be evolved with the impact being very significant mainly due to the direct connection with the physical world and the consequent operational damage.”

The maritime OT world includes systems like:

  • Vessel Integrated Navigation System (VINS)
  • Global Positioning System (GPS)
  • Satellite Communications
  • Automatic Identification System (AIS)
  • Radar systems and electronic charts

 

These technologies and systems provide significant efficiency gains for the maritime industry.

They also present risks to critical systems and processes linked to the operation of systems integral to shipping.

These risks may result from vulnerabilities arising from inadequate operation, integration, maintenance, and design of cyber-related systems as well as from intentional and unintentional cyberthreats.

To address the cyberthreats, it is important to consider the uniqueness of OT systems, as these assets control the physical world. There are certain challenges to consider, such as:

  • OT systems are responsible for real-time performance, and response to any incidents is time-critical to ensure the high reliability and availability of the systems.
  • Access to OT systems should be strictly controlled without disrupting the required human-machine interaction.
  • Safety of these systems is paramount, and fault tolerance is essential. Even the slightest downtime may not be acceptable.
  • OT systems present extended diversity with proprietary protocols and operating systems, often without embedded security capabilities.
  • They have long lifecycles, and any updates or patches to these systems must be carefully designed and implemented (usually by the vendor) to avoid disrupting reliability and availability.
  • The OT systems are designed to support the intended operational process and may not have enough memory and computing resources to support the addition of security capabilities.

Disruption of the operation of OT systems may impose significant risk to the safety of onboard personnel and cargo, cause damage to the marine environment, and impede the ship’s operation.

Safety warning from USCG

In fact, it was only last July that the U.S. Coast Guard issued a safety alert warning all shipping companies of maritime cyber-attacks.

The incident that led to this warning happened in February 2019 when a large ship on an international voyage bound for the Port of New York and New Jersey reported “a significant cyber incident impacting their shipboard network.”

The Coast Guard led an incident-response team to investigate the issue and found that “although the malware significantly degraded the functionality of the onboard computer system, essential vessel control systems had not been impacted.”

A series of incidents

  • This was not the first time the U.S. Coast Guard had released a cyber safety warning.
  • In May 2019, they published a bulletin to raise the awareness of maritime stakeholders of “email phishing and malware intrusion attempts that targeted commercial vessels.”

A cyber incident in ships might have severe consequences for the crew, the passengers, and the cargo on board.

Considering that many ships carry harmful substances, a cyber incident might have severe environmental consequences or might lead to hijacking the ship to steal the cargo.

The Baltic and International Maritime Council (BIMCO) has defined a cyber safety incident any incident that leads to “the loss of availability or integrity of safety critical data and OT.”

Cyber safety incidents can be the result of:

  • a cyber security incident, which affects the availability and integrity of OT (for example, corruption of chart data held in an Electronic Chart Display and Information System (ECDIS))
  • a failure occurring during software maintenance and patching
  • loss or manipulation of external sensor data that’s critical to the operation of a ship including but  not limited to Global Navigation Satellite Systems (GNSS)

Best practices to mitigate maritime cyber threats

In 2017, the International Maritime Organization (IMO) adopted resolution MSC.428(98) on Maritime Cyber Risk Management in Safety Management System (SMS).

The Resolution stated that an approved SMS should consider cyber risk management and encourages administrations to ensure that cyber risks are appropriately addressed in safety management systems.

The same year, IMO developed guidelines that provide high-level recommendations on maritime cyber risk management to safeguard shipping from current and emerging cyber threats and vulnerabilities.

In addition, BIMCO has developed the Guidelines on Cyber Security Onboard Ships, which are aligned with the NIST Cybersecurity Framework.

To achieve this goal, maritime companies should follow these best practices:

  • Identify the threat environment to understand external and internal cyber threats to the ship.
  • Identify vulnerabilities by developing complete and full inventories of onboard systems and understanding the consequences of cyber threats to these systems.
  • Assess risk exposure by determining the likelihood and impact of a vulnerability exploitation by any external or internal actor.
  • Develop protection and detection measures to reduce the likelihood and the impact of a potential exploitation of a vulnerability.
  • Establish prioritized contingency plans to mitigate any potential identified cyber risk
  • Respond and recover from cyber incidents using the contingency plan to ensure operational continuity.

“Maintaining effective cybersecurity is not just an IT issue but is rather a fundamental operational imperative in the 21st century maritime environment,” said the U.S. Coast Guard in their July 2019 security warning.
