Research on cloud computing in the key technologies of railway intelligent operation and maintenance sharing platform

Abstract

Cloud data center has become a trend and mainstream, and the first phase of the main data center of National Railway Group has been completed, and the main data center also adopts cloud computing technology. Compared with traditional data centers, cloud data centers bring great convenience of unified and flexible resource scheduling to railroads, but also bring many new security risks. Therefore, the study of security architecture and key technologies for cloud data centers becomes an important requirement for securing railroad cloud data centers. While cloud computing brings convenience to railroads, it also brings new security risks. By studying the information security model, we construct a cloud security architecture that meets the actual situation of railroads. In terms of responsibility, according to the level protection responsibility sharing model should be divided into cloud-based security protection and cloud platform foundation protection; in terms of construction, according to the sliding scale model, it should overlap and evolve, and gradually complete the security construction in several stages of infrastructure security, deep defense, active defense and threat intelligence.
