Applying a Risk-based Approach for ensuring Network Connection Safety in a Maritime Environment

In this paper a risk-based approach is applied to a maritime use case in order to guarantee dependable operation of the involved network connection. The dynamic positioning control system is studied, specifically the network communication, and a case scenario is considered in which Electro-Magnetic Interference (EMI) induced failures remain undetected at the network level. Electromagnetic diversity is proposed as an electromagnetic resilience measure to deal with such EMI induced failures already at the network level.
