*1 Transmission-Interference techniques may cause a Denial-of-service condition on the bus
*2 These devices use Transmission-Interference, which might cause network reliability issues, or even be exploited to perform a Denial-of-service attack
*3 Transmission-Interference is usually performed by causing intentional bit collusions or transmitting NACK bits in violation of CANBUS standards
*4 Protection against attacks originating from devices that were installed after the vehicle was manufactured, by either the vehicle owner or the dealership
