Abstract (en)
[origin: WO2020247993A1] The invention relates to a method for checking the security of a technical unit (1), wherein at least one first plausible model variant and, as applicable, a number of alternative model variants are determined, the method being performed on a test computer system (2) and comprising the following steps: assigning known weak points to components of the model variants; defining an attack target; creating at least one attack model for each model variant on the basis of the attack target; weighting the nodes of the attack model in respect of at least one assessment variable; determining an assessment of at least one test vector of the attack model in respect of the assessment variable; determining a security value as pessimal value of all assessments; and outputting a security confirmation if the security value complies with a security criterion.
