We are presenting four lines of evaluation. First, in order to demonstrate that the requirements as they are demanded for a Break-Glass solution are fulfilled by our approach, in section 9.1 we will compare the requirements listed in section 3.1 with the properties of our solution. To show the generalizability of our approach, second, we have shown how existing approaches can be modeled along our Break-Glass model (chapter 8) and will present an approach to classify existing Break-Glass approaches along our Break-Glass model in section 9.2. Third, we will show how to model Break-Glass on top of a selected set of Access Control (AC) models in section 9.3. Fourth, to demonstrate the feasibility of the presented approaches, we have described a prototypic implementation in chapter 7.
