To tackle this rising risk the International Maritime Organization published high-level requirements for cyber risk management in 2017. These requirements obligate organisations to establish procedures, like incident response plans, to manage cyber-incidents. However, there is currently no standardised framework for this implementation. This paper proposes a Cyber Emergency Response Procedure (CERP), that provides a framework for organisations to better facilitate their crew’s response to a cyber-incident that is considerate of their operational environment. Based on an operations flowchart, the CERP provides a step-by-step procedure that guides a crew’s decision-making process in the face of a cyber-incident. This high-level framework provides a blueprint for organisations to develop their own cyber-incident response procedures that are considerate of operational constraints, existing incident procedures and the complexity of modern maritime systems. %@ 2083-6473 %R 10.12716/1001.17.02.02
