The maritime industry with its main components—port logistics, ships, cargo and container distribution systems, autonomous control and navigation systems, global identification and navigation systems—is a substantial and plausible target of cyberattacks. The goal of the present study is to reveal and de-scribe all components of the shipping industry’s cybersecurity policy, the main types of cyberattacks, methods, means, and stages of implementation, cyber vulnerability assessment of on-board information and communication systems, as well as technological measures for cyber defence.
