What is it about?
The paper presents the concept of a risk assessment approach, which can be applied to both safety and security aspects. For including the response of the system to risk management actions, simulations are used. The advantages of the method are shown by means of power grids as a potential application domain.

Why is it important?
A unified treatment of safety and security risks is necessary for taking trade-offs and interactions between them into account. In this way, an adequate risk assessment becomes possible even in the case of e.g. contradictory safety and security aims. Simulations, on the other hand, can represent even an ongoing interplay between safety problems, security problems, and the developing system dynamics. This makes the proposed approach more general than other methods.
Perspectives
The continuously growing complexity of systems challenge traditional risk assessment methods executed by hand. I think, a model-based risk assessment process, which includes the situation dynamics, will turn out beneficial in this respect. Such an approach will help us to successfully handle complex phenomena like fault propagation, back-reactions of the system on failure management, action sequences of intelligent adversaries, and interacting control loops.
