Automobile internal network security early warning method and system

Abstract

The invention discloses an early warning method for safety of an internal network of an automobile. The early warning method comprises the following steps: S10, establishing network connection between the internal network of an automobile and remote early warning monitoring equipment through a network security gateway, a vehicle-mounted terminal and a communication processing unit; Step S11, after the network security gateway detects a network security threat, sending a network security event to the vehicle-mounted terminal, and transmitting the network security event to remote early warning monitoring equipment through a communication processing unit; S12, after the remote early warning monitoring equipment receives the reported network security event, obtaining a security early warning level corresponding to the network security event, performing early warning processing by adopting a corresponding early warning form, and displaying on a screen of the early warning monitoring equipment. Meanwhile, the remote early warning monitoring equipment also supports the query processing of the reported network security events. The invention further discloses a corresponding system. By implementing the method and the system, support is better provided for analyzing and processing the security problem of the internal network of the automobile.

Description

technical field [0001] The invention relates to the technical field of vehicle internal network security, in particular to an early warning method and system for vehicle internal network security. Background technique [0002] At present, many cars on the market already have network connection functions, and the internal network of the car has also evolved from the traditional CAN network to the Ethernet, which also brings some security problems to the internal network of the car. [0003] In the existing technology, for example, the patent application with the publication number 108521410A published by the Patent Office of the State Intellectual Property Office on September 11, 2018, which is titled "Security Protection Architecture for Vehicle Ethernet", proposes a vehicle-mounted Ethernet's four-layer network security protection architecture, including external interface security, gateway security, network security, and access security. External interface security includ...

Problems solved by technology

[0004] However, the existing technical solution only focuses on how to achieve network security protection, and does not mention how to deal with network security problems after they occur

Similarly, there is no suitable solution in the prior art for how to detect whether the automobile network is under attack and whether it is facing network security threats.
