Research on Classification and Grading Method of Data during Railway Construction Period of Railway Engineering Construction Management Information System
This paper studies and discusses the classification and grading of data during railway construction period and corresponding safety protection strategies.In terms of data classification,according to the informatization planning and its own management status of China State Railway Group Co.,Ltd.,the data is divided into 5 primary subcategories of services and further divided into multiple secondary subcategories of services to generate a detailed data classification table.According to the national planning and the characteristics of railway construction,each secondary subcategory of services is carefully divided to build a multi-level data category system.In terms of data grading,the data is divided into 4 security levels from low sensitivity to extreme sensitivity by taking into account the impact object,impact scope,controllability degree,impact degree and sensitivity degree,providing a clear hierarchical division in terms of data security.In order to meet the security requirements in data activities,this paper proposes a data and network security protection system from technical security,management security and network security:specifically,in terms of technical security,the four-level security protection strategy for acquisition,transmission,storage,processing,sharing and destruction is clarified to ensure data security from the perspective of full life cycle;in terms of management security,the management measures such as safety review,inspection and assessment,emergency response and safety supervision are specified,thus specifying the safety management process of relevant operations;in terms of network security,each organization shall be equipped with boundary security device and unified terminal security management software,and different levels of network security protection shall be defined to ensure the stability of the network and the secure transmission of data.This study provides a comprehensive analysis and solution for classification and grading as well as security protection of data during railway construction and provides theoretical and practical guidance for data management in the field of railway engineering construction.
