A security analysis and early warning method for vehicle networking data

By constructing a three-tiered defense system of cloud-pipe-end and the TARA+HEAVENS integrated assessment method, the problems of threat generalization throughout the entire lifecycle and fragmentation of the defense system in vehicle network data security have been solved. This has enabled accurate threat identification, real-time risk warning and standardized evaluation throughout the entire lifecycle, thereby improving the defense effect and the accuracy of the evaluation.

AI Technical Summary

⚠Technical Problem

Current technologies for vehicle-to-everything (V2X) data security face challenges such as the generalization of threats throughout the entire lifecycle, fragmented defense systems, lack of early warning mechanisms, and non-standard assessment methods. Furthermore, existing risk assessment methods are too simplistic, resulting in insufficient accuracy in threat level determination.

⚗Method used

We construct a three-tiered data security defense system encompassing cloud, network, and endpoint, employing the TARA+HEAVENS integrated risk assessment method to achieve full lifecycle security analysis and real-time risk warnings. Combining full-process data security analysis, real-time risk warnings, and standardized assessments, we deploy closed-loop security measures throughout the entire lifecycle.

🎯Benefits of technology

It achieves accurate threat identification and defense throughout the entire lifecycle, improves the accuracy of threat rating, enables real-time risk warning and coordinated response, reduces security incident losses, and enhances the standardization of defense effectiveness and evaluation.

Abstract

This invention relates to the field of intelligent connected vehicle data security technology, specifically to a method for security analysis and early warning of vehicle network data. Based on the full lifecycle flow path and multi-dimensional security threat analysis of intelligent connected vehicle data, it constructs a three-layer hierarchical data security defense system of cloud-pipe-end, and forms a four-dimensional security evaluation mechanism of confidentiality, integrity, availability, and traceability adapted to all scenarios. This enables full-process security analysis, real-time risk early warning, and standardized evaluation of vehicle network data, systematic management throughout the entire lifecycle, and full coverage of threat identification. This invention constructs a flow topology model based on the full lifecycle of data, implements a cloud-pipe-end hierarchical defense, and coordinates protection capabilities. This invention creates a three-layer collaborative defense system, a four-level real-time early warning closed loop, and zero-lag risk handling. This invention establishes a graded early warning and linkage handling mechanism, four-dimensional standardized evaluation, and quantifiable defense effects.
