Abstract : Operating in constrained environments and composed of heterogeneous subsystems, today's ships are among the most complex objects that exist. Due to the increasing number of cyber assets among their components, patch and vulnerability management applied to naval systems is an essential process. The work detailed in this PhD thesis aims to define such a process tailored to complex cyber-physical systems. This process relies on a modelling method and formalism allowing to depict CPS behaviour and cyber events – a vulnerability discovery, a cyber attack occurrence or a patch deployment. It also relies on an impact assessment method, allowing to compute the effects of cyber events on CPS ability to fulfill their missions.These impacts are expressed through a specially designed metric aiming to help in decision-making. The process, methods, formalisms and metrics we propose in this work are then evaluated through an experimentation based on a fictitious case-study.
