基于星载网络探针的通信卫星信息安全监测系统设计

Design of the Monitoring System for Communication Satellite Information Security Based on Spaceborne Network Probe

为提升通信卫星信息安全防护能力,在星上资源受限的情况下,实现系统信息安全监测,在比较部分典型信息安全防护设计的基础上,梳理通信卫星系统基本特性和面临的安全威胁,分析并总结安全防护能力提升的制约因素,提出一种利用星载网络探针技术采集卫星安全数据,依托地面系统构建数据分析平台和综合监测系统的信息安全监测方法,在资源占用度较低的前提下保证卫星业务正常运行,实现系统安全监测和安全告警,并对系统实际工作运行展开分析和验证。

To enhanced the information security protection capability of communication satellites and solved the information security monitoring problem of the system under the condition of limited on-board resources,based on the comparison of some typical information security protection designs,this paper summarized the characteristics and security threats of the communication satellites,analyzed the constraints on improved security protection capabilities,then proposed a sort of collecting satellite security data by using space based probe technology,built data analysis platform and integrated monitoring system based on the ground system,which could realized the system security status monitoring and security alarm on the premise of ensuring the normal operation of the satellite business and low resource occupancy.At last the actual operation of the system was analyzed and verified.
