Trends in international and domestic maritime cybersecurity guidelines

International maritime organizations such as IMO, IACS, and BIMCO are actively promoting the development and dissemination of cybersecurity guidelines as the threat of cyber attacks increases rapidly due to the digitalization of ships and the digital transformation of shipping and port operations. Accordingly, in Korea, Maritime Safety Primary Act and Cyber Safety Management Guidelines are being enacted and implemented in 2023 to accelerate the safety of ship operations. In this paper, we examine the development trends of maritime and shipping cybersecurity guidelines that are actively underway at home and abroad and suggest the direction of development of domestic maritime cybersecurity policies in the future.
