Intelligent networked automobile vehicle security asset identification method based on domain division and service division

Abstract

The invention discloses an intelligent networked vehicle information security asset identification method based on domain division and service division, and the method comprises the following steps: 1, carrying out the domain division of an intelligent networked automobile, and building an electrical function domain of the highest level; step 2, classifying the assets of the functional domains ofthe intelligent networked vehicles, namely, firstly, dividing electrical functions of a whole vehicle level, classifying the assets of the intelligent networked vehicles, and then, concluding the assets of the same electrical functional domains to form a preliminary asset list; and step 3, identifying assets on the basis of the service process, identifying a specific case of a specific system of the intelligent networked vehicle, and identifying service process assets of the specific case. According to the intelligent networked vehicle information security asset identification method based onthe domain division and the service division, through the arrangement of the first step to the third step, the vehicle information security assets can be effectively identified after the domain division and the service division.

Description

technical field [0001] The present invention relates to an asset identification method, and more specifically relates to an intelligent networked vehicle information security asset identification method based on domain division and business division. Background technique [0002] With the continuous improvement of automobile intelligence, network connection and electrification, the information security problem of intelligent network connection vehicles is becoming more and more serious. Methods such as information tampering and virus intrusion have been successfully used by hackers in automobile attacks, especially in recent years. The auto information security recall event has aroused great concern in the industry. The information security crisis of intelligent networked vehicles can not only cause personal privacy and corporate economic losses, but also cause serious consequences of car crashes and deaths. It has now risen to a national public security issue. It is immine...

AI Technical Summary

Problems solved by technology

The former classification is logical, but in actual operation, it will be difficult to assign values ​​effectively due to too many and too detailed assets

Currently there is no unified and comprehensive asset classification standard, and asset classification varies from person to person, resulting in difficulties in communication and communication

Moreover, certain assets are closely connected, which leads to the overlap of certain security attributes of these information assets. The value assignment of these information assets on the security attributes directly leads to repeated assignment of the security value of these information assets, which seriously affects the evaluation results. Accuracy

The latter is a better approach in terms of asset identification, but it overemphasizes the importance of identifying core business assets while ignoring non-critical business assets

Overemphasizing the importance of the information assets of the core business to the organization and denying the possibility of key information assets in non-critical businesses will lead to the possibility of weakening the security attribute of an information asset
