Satellite network security analysis method and system

The invention provides a satellite network security analysis method and system, and relates to the technical field of satellite information security, and the method comprises the steps: obtaining the security monitoring data of a to-be-analyzed satellite and twin satellites in a current operation period, the twin satellites and the to-be-analyzed satellites are completely the same satellites and are used for receiving and executing the same remote control instruction; preprocessing the safety monitoring data to obtain target safety monitoring data; and performing comparative analysis on the target security monitoring data of the to-be-analyzed satellite and the target security monitoring data of the twin satellites, and determining the network security situation of the to-be-analyzed satellite, thereby solving the technical problem of lagging of satellite network security defense in the prior art. 本发明提供了一种卫星网络安全分析方法和系统，涉及卫星信息安全的技术领域，包括：获取待分析卫星和孪生卫星在当前运行周期内的安全监测数据，其中，孪生卫星与待分析卫星完全相同的卫星且孪生卫星与待分析卫星用于接收并执行相同的遥控指令；
