Although multiple approaches for the combination of safety and security analysis exist, there are still some major gaps to overcome before they can be used for combined risk management. This paper presents the existing gaps, based on an overview of available methods, which is followed by the proposal towards a solution to achieve coordinated risk management by applying a quantitative security risk assessment methodology. This methodology extends established safety and security risk analysis methods with an integrated model, denoting the relationship between adversary and victim, including the used capabilities and infrastructure. This model is used to estimate the resistance strength and threat capabilities, to determine attack probabilities and security risks.
