Cybersecurity for an industry where digital risk can become operational risk.
Modern maritime operations depend on interconnected information technology, operational technology, navigation, communications, cargo and shore-based systems.
As vessels, ports and maritime businesses become more connected, cybersecurity must extend beyond traditional enterprise IT. A weakness in an exposed application, remote-access channel, network, onboard system or third-party connection can affect confidentiality, integrity, availability and operational resilience.
- Assess vessel and shore-based attack surfaces.
- Evaluate connected IT, OT, applications and networks.
- Prioritize risks according to operational impact.
Where maritime cyber risk can originate
Maritime environments combine enterprise IT, shipboard operational systems, communications, third parties and physical operations. Effective maritime cybersecurity therefore considers both cyber exposure and operational impact.
Shipboard IT & OT
Connected navigation, engineering, cargo and operational systems can create attack paths between environments.
Ship-to-Shore Connectivity
VSAT, remote access, fleet management and shore connectivity expand the maritime attack surface.

Frequently Asked Questions About Maritime Cybersecurity
Find answers to common questions about maritime cybersecurity, vessel security assessments, IT and OT environments, IACS requirements and maritime cyber risk management.
Maritime cybersecurity protects the information technology (IT), operational technology (OT), connected systems, networks, applications and data used across ships, ports, maritime operators and supply chains from cyber threats. It combines cyber risk management, security assessment, technical testing and resilience measures to reduce the potential impact of cyber incidents on safety, operations and business continuity.
A maritime cybersecurity assessment can evaluate vessel and shore-based IT and OT environments, network architecture, segmentation, remote access, connected systems, applications, cloud services, third-party connections and security controls. Depending on the approved scope, it may also assess navigation, communication, cargo, engineering and other operational systems to identify vulnerabilities, cyber risks and potential attack paths.
Depending on vessel architecture and approved scope, a vessel cybersecurity assessment may cover ECDIS, AIS, GNSS, radar, VDR, GMDSS, VSAT, onboard networks, cargo systems, engineering and machinery systems, remote access, crew networks and ship-to-shore connectivity. The assessment should also consider how these systems interact with enterprise IT, OT and third-party services.
Yes. Maritime cybersecurity should consider both information technology (IT) and operational technology (OT), including how systems are connected and how a cyber incident could affect vessel operations, safety or business continuity. Assessments may examine network segmentation, remote access, system dependencies, third-party connections and controls protecting critical operational environments.
IACS UR E26 addresses the cyber resilience of ships, while UR E27 addresses the cyber resilience of onboard systems and equipment. They establish cybersecurity requirements relevant to the design, construction, integration and operation of applicable new ships and onboard systems. The current revised requirements should be considered when determining the cybersecurity expectations applicable to a specific vessel, system or project.
Depending on the organization's role, vessel type and scope, relevant maritime cybersecurity requirements and standards may include IMO maritime cyber risk management guidance, IMO Resolution MSC.428(98), the ISM Code, IACS UR E26 and E27, BIMCO industry guidance, ISO/IEC 27001, IEC 62443 for relevant OT environments and applicable national cybersecurity requirements. The appropriate requirements should be determined based on the organization's operational and regulatory context.
