- To ensure safety and security of highly automated driving systems one shall make sure all risks are reduced to a reasonable level and an all potential cyberattacks are addressed with necessary protection. Because of the complexity of such vehicle systems, systematic and structured management approaches are vital to maintaining safety via cybersecurity (CS). The interface of Safety Management System (SMS) with Cybersecurity Management System (CSMS) is one of the key aspects to ensuring that potential safety issues are addressed. Both management systems include planning, concepts, and process development, with significant areas of overlapping management systems is required. Regarding the management systems interface and distribution, it is still a challenge that Highly Automated Driving (HAD) vehicles needs to overcome by means of effective implementation and strategies with continuous improvement and a reduction of miscommunication. From that motivation, a set of engineering risk management framework are proposed in this paper. Subsequently, introducing the interface areas between the safety and the cybersecurity domain is one of the focus areas of this paper, together with the representation of the interface management activities with exemplary interaction template. Additionally, mapping in between safety and cybersecurity related standards in terms of evidence and management systems is represented partially to support both safety case and security assurance.
