With the advent of smart ships, cyber security threats to ship control system are increasing. In order to strengthen ship cyber security, the IACS issued UR E26 in April 2022 and declared it to be applied to ships contracted for construction on July 1, 2024. Therefore, in this paper, we conduct research on ship networks that can respond to cyber threats by considering the distinct characteristic of the ship network construction environment and the requirements of IACS UR E26. For this purpose, we analyzed the reference model of IEC 62443 along with the requirements of IACS UR E26. In addition, we identified the network structure and characteristics of the recently built smart ship. Based on this, we propose a ship network model that includes the configuration setting of the network and security device along with the deployment of the OT/IT device in the ship. Finally, we applied the proposed ship network security model to the network of recently built smart ships to verify its function and performance.
Abstract
With the advent of smart ships, cyber security threats to ship control system are increasing. In order to strengthen ship cyber security, the IACS issued UR E26 in April 2022 and declared it to be applied to ships contracted for construction on July 1, 2024. Therefore, in this paper, we conduct research on ship networks that can respond to cyber threats by considering the distinct characteristic of the ship network construction environment and the requirements of IACS UR E26. For this purpose, we analyzed the reference model of IEC 62443 along with the requirements of IACS UR E26. In addition, we identified the network structure and characteristics of the recently built smart ship.

Finally, we applied the proposed ship network security model to the network of recently built smart ships to verify its function and performance.
