Abstract

Abstract:

With application status of the China Petroleum Refining and Chemicals run system MES（manufacturing execution system）in subordinate enterprises as well as the data acquisition interface program in real-time database module, the security risks such as virus, attacks and illegal invasions in production unit automatic control system （DCS, PLC）because of the “two-network integration”were analyzed. Finally, referring to some of the existing domestic industrial insulation products, a complete, viable and secure solution, which has a high reference value for the implementation of petrochemical enterprises MES system real-time database module was proposed.

Key words: MES, real-time database, OPC and computer virus, DCS/PLC system security

标题	防火墙	隔离网关
工作原理	基于TCP/IP协议体系，以数据分组过滤技术为基础，对内网和外网间、专网与公网间通信信息进行处理，拦截不需要的数据分组，允许需要的数据分组通过	网关主要用于两个协议不同的网络互连，在使用不同协议的网络区域间转换通信协议，对收到的信息重新分组，以适应目的系统的协议需求
主要局限	不能保证通讯放行数据分组的安全性，难以阻止已经感染病毒的程序和文件传输	网关可根据不同场合融合不同的协议转换技术和网络安全功能，具有重要且独特的保护作用，但仍存在TCP/IP自身协议缺陷
	只能控制网络四层以下的数据分组，无法阻止因系统漏洞带来的攻击，难以有效防范应用层内蠕虫等病毒	安全网关虽然具有防火墙的功能，具有一定的入侵检测防御、流量控制等功能，但只能实现逻辑上的网络隔离，不能实现物理意义上的网络隔离
