Abstract
In one embodiment, a device of a vehicle receives a packet comprising a source address, a destination address, an internet protocol (IP) encapsulated controller area network (CAN) message, and CAN message identifier information. The device compares the source address, the destination address, and the CAN message identifier information to an access control list (ACL). The device makes a determination that delivery of the CAN message to the destination address would be a policy violation based on the comparison. The device drops the packet based on the determination that delivery of the CAN message to the destination address would be a policy violation.
