Abstract
Methods and systems are provided for detecting vehicle controller spoofing. The vehicle includes a plurality of vehicle controllers, a vehicle network switch, and a content addressable memory (CAM). The plurality of vehicle controllers includes first and second vehicle controllers. A first port of the vehicle network switch is designated to only receive data frames from a first vehicle controller. The first vehicle controller is associated with a first media access control (MAC) address. The CAM is configured to store an association between the first port and the first MAC address, receive a first data frame including a source MAC address at the first port, determine whether the source MAC address matches the first MAC address, and generate an anomaly event based on the determination. A generated anomaly event indicates that the first vehicle controller is masquerading as the second vehicle controller using an invalid source MAC address.
