IP模式测控系统实时数据库的安全性研究

Study on Security for Real-time Database of IP Mode Measurement & Control System

分析IP模式测控平台实时数据库的安全威胁,提出系统的安全保护体系模型,阐述包括基于网络空间的数据备份、控制命令编码及被屏蔽子网等关键技术。基于《可信计算机系统评测标准》对所设计系统的安全性进行评价,结果表明,其安全等级介于B2和B3等级之间,具有较高的安全性能。

Possible threats to real-time database of IP mode measurement and control system were analyzed. Then the model on safety system was brought forward and some key technologies were presented, including data backup based on networked space, code of control command and shielded subnet, etc. By means of ＂Test Computer System Evaluating Criterion （TCSEC）＂, the design on security for real-time database of IP mode measurement and control system was evaluated. The results show that the real-time database of IP mode measurement and control system which safety rank is between B2 and B3 nossesses high securitv performance.
