Railway Information Sharing Platform Security Requirements Analysis

摘要

Railway information sharing platform is the key technology to realize the railway information systems connectivity, integration and optimization of all kinds of information resource in railway companies. The system security requirements analysis is the foundation of controlling the system security. With the technical features analyzed and the key business processes described, information security requirements are pointed out as access control security, information transmission security, data storage security and building a unified security control center. Demand analysis is the premise of railway information sharing platform security technology implementation. Due to historical reasons, Most Chinese railway information systems have little interactions and become "Information Island". In order to solve these problems, in urgent need of the construction of railway information sharing platform, connecting the various systems to share information, optimizing the overall effect of system construction. To ensure information security of the information sharing platform, the first thing to do is to make it clear that what security demands of the platform are. In the paper, the key security requirements are put forward to laying the foundation for the system security.
