Attack defense method, device and equipment and storage medium

Abstract

The invention discloses an attack defense method, device and equipment and a storage medium, relates to the technical field of information safety, and the method and the device can be used for intelligent transportation or automatic driving scenes. According to the specific implementation scheme, the method comprises the steps of obtaining an instruction set comprising at least one instruction forcontrolling the state of the vehicle, and respectively comparing each instruction in the instruction set with at least one attack instruction in an attack behavior knowledge base, determining a maximum similarity value corresponding to each instruction, and determining the type and processing strategy of each instruction according to the maximum similarity value corresponding to each instructionand a preset similarity range. According to the technical scheme, each attack instruction in the attack behavior knowledge base is obtained by performing attack analysis on the chain type data set ofat least one vehicle-mounted component, and the context data of the source data is associated when the attack instruction is generated, so that the accuracy of the determined instruction type and theattack defense precision are improved.

Description

technical field [0001] The embodiments of the present application relate to the field of information security technology in the field of data processing technology, and in particular to a method, device, device, and storage medium for defending against attacks. Background technique [0002] With the development of Internet of Vehicles technology, there are more and more smart vehicles. For example, after connected to the network, smart vehicles can perform real-time road navigation, download video and audio, and voice interaction. However, the Internet of Vehicles brings convenience to users in life and travel At the same time, many potential safety hazards may also be added. For example, criminals can attack any connected vehicle through the network, steal data in the vehicle, and even seize driving control rights, thereby threatening human life and property safety. [0003] In the prior art, in order to improve the information security of the Internet of Vehicles, the gene...
