摘要
依据物理隔离与专网防护的传统思路,工业控制系统(ICS)亟需解决"内在"的功能安全和"外在"的信息安全问题,以及构建"可信、可管、可控"环境下的ICS典型信息安全验证场景。为了适应ICS信息安全问题的研究与验证,基于ICS五层结构模型,建立工控信息模型并利用MATLAB来模拟电厂现场实际物理过程,利用Lab VIEW软件构造监控系统操作界面,通过OPC协议及共享变量引擎SVE实现Lab VIEW与MATLAB之间的实时数据交换,同时通过PLC来对现场数据进行采集,构建了ICS半实物仿真模型,对ICS信息安全防护提供了一种新思路。
According to the traditional idea of physical isolation and private network protection,industrial control system( ICS) urgently needs to address the inherent functional security and external information security issues,as well as the construction of trusted,manageable,controllable ICS typical information security verification scenes. In order to adapt to the research and verification of ICS information security problem,this research is conducted based on the ICS five-layer structure model. Industrial information model is adopted to establish and use the MATLAB to simulate the actual physical process of power plant. Lab VIEW software is used to construct the monitoring system operation interface. Real time data exchange between Lab VIEW and MATLAB is realized by OPC protocol and shared variable engine( SVE). The collection of the field data is realized by PLC,and the data constructs the ICS semi-physical simulation model. A new idea for ICS information security protection is provided.
