Following a number of high profile security incidents affecting both the information and operations assets of several industry and business sectors in recent years, the need to consider the risks associated with the use of innovative technologies in a number of production and business processes and environments has never been greater. The maritime sector, like many others, is exposed to a number of potential hazards that need to be assessed and addressed. On the assumption that in the last few years Information and Communication Technologies (ICT) have been widely applied in the processing of information and support operations, then passenger and cargo ships, yachts, supply and offshore vessels, as well as waterways transport, harbour facilities and infrastructures are all relevant... elements in international cyber risk assessment programs. Similar to hazards associated with other technologies and activities, the ‘cyber environment’ needs to be considered through appropriate risk assessment processes and the subsequent risks that are identified need to be mitigated by appropriate measures. The rapid evolution of digital and information technologies that attract marine operators and owners by optimising and improving their business demands a similar continuous evolution of protective techniques and testing procedures. This paper will explore the cyber environment and focus on the management of the cyber risk in the marine industry.
