Abstract

The embodiment of the invention discloses a vehicle information security threat assessment method and device, a medium and electronic equipment. The method comprises the following steps: determining a function safety target and an information safety target according to related item definitions and application scenes of a vehicle, wherein the definition of the related items is composed of at least one system in the vehicle, and the functions of the whole vehicle can be achieved or partially achieved; determining an attack tree model by using the function security target and the information security target; and attacking the attack tree model through an attack method to obtain a vehicle information security threat. According to the technical scheme, the information security technology and the function security technology can be fused, the vehicle risk is assessed based on the multi-dimensional attack method, and the accuracy of vehicle security threat assessment is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of intelligent networked vehicle information security, and in particular to a vehicle information security threat assessment method, device, medium, and electronic equipment. Background technique [0002] With the rapid development of the market economy, people's living standards are constantly improving. At the same time, the number of vehicles is also increasing year by year. However, due to frequent traffic accidents, it has caused great casualties and economic losses. Therefore, the safe operation of vehicles is very important. [0003] In the development of intelligent networked vehicle information security, in order to determine the risk level of the whole vehicle, the vehicle security threat assessment model is established by combining the STRIDE method to evaluate the vehicle security threat. [0004] The STRIDE method is used to establish a vehicle security threat asses...
