Abstract
A system for in-vehicle network intrusion detection includes a microcontroller having first and second cores and memory. The first core may be configured to obtain one or more network messages from one or more communication buses of a vehicle describing one or more events associated with the vehicle. The memory may be configured to store the one or more network messages obtained by the first core. The second core may be configured to: (i) read the one or more network messages from the memory; (ii) detect whether at least some of the one or more events constitute an anomaly based on predefined rules; (iii) generate one or more resident incident logs including metadata associated with one or more detected anomalous events based on the detected anomaly event data; and (iv) generate one or more transmitted incident logs based on the one or more resident incident logs.
