Abstract
Systems, methods, and software can be used to configure a firewall system in a vehicle network. In some aspects, a computer-implemented method includes receiving a software code of a network node connected to a trusted network of a vehicle network that includes the trusted network internal to a vehicle and an untrusted network external to the vehicle, wherein the trusted network includes one or more functional domains for controlling functionalities of the vehicle; performing an analysis of the software code to identify connectivity of the network nodes in the vehicle network; determining connectivity information of the network nodes in the vehicle network based on the analysis, wherein the connectivity information includes at least one of Network Layer connectivity information, Transport Layer connectivity information, or Application Layer connectivity information; and configuring one or more firewalls in the vehicle network based on the connectivity information.
