Intrusion detection method and device of vehicle-mounted network, vehicle and storage medium

The invention relates to the technical field of network security, in particular to an intrusion detection method and device for a vehicle-mounted network, a vehicle and a storage medium, and the method comprises the steps: obtaining a network traffic packet of the vehicle-mounted network; detecting feature information of the network traffic packet, determining a target matching mode according to the number of features in the feature information, and matching the features in the feature information with attack features in a preset rule base according to the target matching mode; and if any feature in the feature information is matched with the attack feature, determining that the network traffic packet is an intrusion traffic packet, and generating a prompt that the vehicle-mounted network is intruded. Therefore, the problems that in the related technology, a vehicle-mounted intrusion detection system is not clear in description of the intrusion behavior, the accuracy of a detection algorithm for the intrusion
