轨道交通自动化系统信息安全应用浅析

Application of Information Security in Railway Transportation Automation System

工业控制系统向工业以太网结构发展,开放性越来越强,基于TCP/IP以太网通讯的OPC技术在该领域得到广泛应用。在工业控制系统中,由于工业系统集成和使用的便利性,大量使用了工业以太环网和OPC通信协议进行了工业控制系统的集成,也大量使用了PC服务器和终端产品,操作系统和数据库,同时还大量使用了通用系统,这样很容易遭到来自企业管理网或互联网病毒、木马、黑客的攻击。为了防止工业控制系统在通信过程中遭受各种威胁与攻击,需要使用多层安全措施来实现对系统的保护。论文从网络边界防护、安全协议和安全控制器方面,介绍了控制系统信息安全问题的解决思路。

The industrial control system to the industrial Ethernet structure development,opening up more and more strong.OPC technology based on TCP/IP Ethernet communication is widely used in this field.In the industrial control system,industrial system integration and the use of convenience,a large number of industrial Ethernet and OPC communication protocol for industrial control system integration;at the same time,also a lot of use of PC server and terminal products,operating system and database also use a general system,it is easy to come from business management network or internet virus,Trojan,hackers attack.In order to prevent the industrial control system in the communication process of the above various threats and attacks,the need to use a multi-level security measures to complete the protection of the system.In this paper,we introduce the information security solution of the control system from the aspects of network boundary protection,security protocol and security controller.
