Methodology for safety and security analysis

This report describes a refinement and further development of a safety and security analysis method developed in AEGIS, and is documented in the modelling tool Enterprise Architect, employing UML diagrams to describe the target system and mission, which is based on methods described in the H2020 AUTOSHIP and Seatonomy projects.This report illustrates the refined methodology by applying it to an example mission based on AEGIS Use Case B, specifically a RoRo barge route between Rotterdam and Ghent. Based on this example mission, a set of System Control Tasks and Mission Phases have been defined, and these are subject to a generic safety and security analysis where activities, threats and risks are described and assessed with the help of various UML diagrams. The analysis is not exhaustive, but rather an example of how the methodology can be used.
