Aiming at the shortcomings of the existing active defense system in the visual display of alarm data, including the lacking of hierarchical display, alarm data linkage function and the weak access control of the alarm data, the paper designs and implements a hierarchical deployment of active defense system visualization display platform. Through the design of three-layer system which contains presentation layer, business logic layer and data access layer, the platform realizes the visualization of security situation, safety analysis and real-time threat perception which are contained in alarm database. Through the multilevel cascaded design of server and multi role user authority design, the access of alarm data is safely controlled within the legitimate users. The experiment demonstrates that the display platform not only provides the situation of defending viruses and Trojans to the leadership, but also informs the related personnel the alarm information to effectively curb the spread of viruses and Trojans.
