Railway network security risk visual analysis method and device

The invention provides a railway network security risk visual analysis method and device, and belongs to the technical field of railway network security. The prototype system of the railway informatization asset surveying and mapping platform adopts a service-oriented system architecture design under the constraint of a technology and industry standard specification system and the constraint of an information security system mechanism, and the overall architecture comprises an infrastructure layer, a data layer, a system support layer, an application layer and a presentation layer. The expansibility of the system is considered, and an extended network system structure of a data and service application system is realized. The railway network security risk visual analysis method comprises the following steps: positioning a railway network security risk visual analysis device; and acquiring and analyzing railway network security risk data by using the equipment main body, and classifying the railway network security risk data into primary risk data, intermediate risk data and advanced risk data. According to the method, the personnel with the corresponding level of authority can obtain the corresponding analysis information.
