Firewall and Intrusion Detection and Prevention Concept for Automotive Ethernet

Vehicles continue to evolve with different technologies introduced into the automotive domain. The amount of data to be processed grows accordingly, resulting in the increase of the number of bugs in software. As the domain becomes more complex with millions of lines of code, new attack vectors appear. When it is vehicles in discussion, the attack surface has to be tackled more carefully as it constitutes the safety of the driver as well as the passengers and other drivers on the road.This paper introduces a conceptual model for Firewall and Intrusion Detection and Prevention System that aims to act as a solid security mechanism for the vehicular communication network
