Technical Solution to Information Security of Intelligent Operation and Maintenance System for Urban Rail Transit Vehicles

Abstract

Objective With the rapid growth of urban rail transit scale, the application of information-based intelligent vehicle operation and maintenance system becomes increasingly extensive, and the information security problem of the intelligent vehicle operation and maintenance system for urban rail transit becomes prominent gradually and needs to be solved urgently. Method Based on the information security risks and problems that the intelligent operation and maintenance system for urban rail transit vehicles may face, such as software vulnerabilities, systematic protection missing, network transmission security, etc., and with reference to a number of national and industrial information security standards, the technical solutions to information security protection are systematically proposed, including security zoning, boundary isolation, vertical authentication, and centralized supervision. The device host security is safeguarded by software hardening, access control, security audit and intrusion prevention.The network transmission security is safeguarded by secure partition, boundary isolation, secure transmission and robust network of the communication networks between vehicle-mounted, vehicle-ground and ground communication networks.The business data security is improved by controlling and protecting the processing steps including storage, transmission, application and destruction.The security of application platform is safeguarded by identity authentication, session management, access control, security audit and intrusion prevention. The security of the whole system management center is implemented through decentralized management and centralized control. Result & Conclusion A systematic, unified and comprehensive information security protection technology system is constructed to prevent the vehicle intelligent operation and maintenance system from malicious attacks and illegal intrusions, and protect the system, so as to achieve safe, efficient and reliable vehicle operation and maintenance in urban rail transit.
