Description:
<jats:title>Abstract</jats:title><jats:p>Cyber-physical systems (CPS), like autonomous vehicles, are intelligent and networked. The development of such systems and its components requires interdisciplinary cooperation between different stakeholders. A lack of system understanding between stakeholders can lead to unidentified and unresolved security threats & safety hazards in early engineering phases, resulting in high costs in product development and potentially compromises compliance with the safety of CPS.</jats:p><jats:p>Model-based systems engineering (MBSE) improves the system understanding between stakeholders by using models.</jats:p><jats:p>However, MBSE approaches only partially address security threats & safety hazards. In particular, their integrative consideration is not taken into account.</jats:p><jats:p>Established security & safety approaches are either only applicable to specific disciplines or only partially consider security threats & safety hazards.</jats:p><jats:p>In the context of this paper we present a method for the resolution of safety relevant security threats in the system architecture design phase using design patterns.</jats:p><jats:p>We illustrate our approach with the example of the automotive sector.</jats:p><jats:p>Finally, we present an evaluation of the method, based on an 8 week project with 67 master students.</jats:p>
