Hongguo Shi · 2014
A railway information sharing platform is the key technology to realize the railway information systems connectivity, integration and optimization of all kinds of information resources 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 interaction and become "Information Island". In order to solve these problems, the need is urgent for the construction of a railway information sharing platform connecting the various systems to share information and optimizing the overall effect of system construction. To ensure security of the information sharing platform, the security demands of the platform must be made clear. In this paper, the key security requirements are put forward for laying the foundation for system security.
