Design of vehicle traffic information security risk evaluation index system based on grey evaluation method

Abstract

Abstract The network security problem of vehicle traffic information system is becoming more and more prominent. In order to effectively defend the system, this paper conducts in-depth research on the network security of vehicle traffic information system and proposes an information security risk assessment system for vehicle traffic control center. Specifically, the vehicle traffic control center is divided into components, and the security attributes of each component of the vehicle traffic control center system are constructed. By studying the information interaction process between the vehicle traffic control center and other subsystems, the security attributes of each component are abstracted; Identify the risk value of the component based on the influence of the component’s security attribute on the risk assessment index, aiming to enhance the security defense capability of the vehicle traffic information system.
