Information Security Risks for Car Manufacturers based on the in-Vehicle Network

Within this thesis we investigate what information security risks result from the used invehicle network architecture. By combining scientific and empirical data an architectural model is constructed in ArchiMateTM. Using this model we categorize vulnerabilities and identify the group that poses the biggest threat to the informations security within cars. We find that most information security risks are due to the protocols used within cars and the interconnectedness of the various vehicular networks. In order to overcome these risks we suggest the development of new networking protocols that are secure by design. Furthermore, car manufacturers should prepare themselves better for potential crisis situations.
