Cybersecurity in Shipbuilding: Why It Must Start at the Shipyard

The maritime industry is undergoing a digital transformation. Increased reliance on automation, integrated operations, and connected systems improves efficiency—but also creates new cyber risks. Prevention is key, and it starts with design.

This article explores cybersecurity by design in shipbuilding, why it must start at the shipyard, and how Fortytwo Security helps stakeholders ensure robust cyber resilience from the very first blueprint.

What is Cybersecurity by Design, and Why Does It Matter?

Cybersecurity by design means embedding security into every aspect of a vessel’s systems from day one. Every onboard system is analyzed, selected, and integrated with cybersecurity as a core requirement—ensuring that vulnerabilities don’t become risks once the vessel is operational.

Neglecting security at the design stage can have catastrophic consequences. The Maersk NotPetya attack, detailed in Wired’s article The Untold Story of NotPetya, the Most Devastating Cyberattack in History, is a prime example. The cyberattack shut down Maersk’s global operations for weeks, paralyzing vessels, ports, and logistics.

To avoid such scenarios, cybersecurity must be a fundamental part of the shipbuilding process:

• Applies to all systems, including those that may not appear security-critical.
• Involves all key stakeholders, such as shipowners, shipyards, integrators, suppliers, and certifiers.

Industry Standards: IACS UR E26 & E27

New regulations reinforce this approach. IACS UR E26 & E27 set cybersecurity resilience requirements for ships and onboard systems:

• UR E26 focuses on securing the onboard environment for safe vessel operations.
• UR E27 ensures manufacturers and OEMs integrate cybersecurity into onboard equipment and operational systems..

Shipbuilders and owners must now ensure compliance with these standards while also preparing for evolving threats.

Cybersecurity Responsibilities in Shipbuilding

Shipowners: Define cybersecurity policies, ensure compliance with IACS standards, and require security measures from shipyards.
Shipyards: Install and integrate secure systems, conduct risk assessments, and implement cybersecurity controls.
Vessel Integrators: Design network architecture, ensure secure integration and implement access controls.
Suppliers: Provide secure equipment and ensure cybersecurity documentation meets compliance standards.
Class Societies: Enforce IMO regulations, conduct audits, and certify cybersecurity compliance.
