基于工业以太网的信息网络安全应用研究

Research on the Information Network Security of Industrial Ethernet

自动化作为现代制造业发展的核心,对工业以太网技术的需求空前巨大。工业以太网在实践应用中既可与现场总线结合,又可单独控制网络以及嵌入式网络控制平台,前景广阔,但也存在诸多安全性问题。针对工业控制网路的信息安全,笔者着重以Modbus TCP协议以及Ethernet/IP协议为代表,分析了其安全性问题及相应的解决措施,以期促进工业以太网技术的升级与完善。

As the core of modern manufacturing industry,automation has an unprecedented demand for Industrial Ethernet technology.In practical application,the Industrial Ethernet can not only combine with field bus,but also independently control network and establish embedded network control platform.The prospect of Industrial Ethernet is broad,but there are also many security problems.Aiming at the information security of industrial control network,this paper analyzes the security problems and the corresponding solutions of Modbus TCP protocol and Ethernet/IP protocol,which is to promote the upgrade and improvement of Industrial Ethernet technology.
