Abstract

The invention discloses a safety protection method and device for a vehicle-mounted system. The method comprises the following steps: S1, generating a corresponding vehicle machine defense rule according to acquired vulnerability information and a defense strategy corresponding to the acquired vulnerability information; S2, issuing the vehicle machine defense rule to a vehicle machine terminal, sothat the vehicle machine terminal performs vulnerability defense according to the vehicle machine defense rule; S3, acquiring vulnerability information fed back by the vehicle-mounted terminal through self-attack detection, and generating a defense strategy corresponding to the fed-back vulnerability information, and further executing the step S1. According to the scheme, vulnerability prediction, defense of the predicted vulnerability, attack detection of the terminal and quick response to attack detection of the terminal can be realized; loophole prediction is provided for the other terminal according to loophole detection and response results of the terminal, circulation is carried out in sequence, and a complete protection ecological cycle for the vehicle-mounted system is formed, sothat safety protection of the vehicle-mounted system can be integrally realized in multiple directions, and an excellent protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a safety protection method and device for a vehicle-mounted system. Background technique [0002] With the continuous development of science and technology and society, the emergence of various intelligent and automated vehicles has greatly facilitated people's work and life, but at the same time it has also spawned many security threats against vehicles. For example, the programmable or remote-controllable on-board system in the vehicle provides a new intrusion channel for illegal intruders, thus posing a great threat to people's property and life safety. [0003] In order to ensure the normal operation of the vehicle-mounted system, methods such as hot patches are usually used in the prior art to protect the security of the vehicle-mounted system. However, the current security protection for vehicle systems is often a single-point protection method, that is, a certain d...
