With the wide adoption of Information and Communication Technology (ICT) in the marine environment, ship systems are increasingly similar to other networked computing systems. The integration of positioning systems with navigational and propulsion control systems and the increasing reliance on Supervisory Control And Data Acquisition (SCADA) systems for monitoring the ship's performance makes modern ships vulnerable to a wide range of cyber security issues. Moreover, frequent or permanent onshore connection makes the ship's communication network a potential target for cyber-criminals. Such attacks can incapacitate the vessel, i.e., through a ransomware attack, or greatly degrade the performance of the ship systems, i.e., causing delays in the propagation of control messages between critical components within the ship. Furthermore, crew members and marine engineers are challenged with the task of configuring security policies for networked devices , using low-level device specific syntax, which is an error prone and time consuming process. In addition to this, crew members must also be familiar with the specific syntax for low-level network management task, which exacerbates the problem.
