本文研究探讨了一种基于虚拟化技术的石化企业过程信息集成的安全策略。在石化企业的办公网/生产专网/控制网络3层结构中,将安全内嵌到基础架构中并进行虚拟化,建立安全服务管理中心对生产专网的安全进行管控和预警,同时将安全作为服务进行交付,从而改变了传统的安全模式。还通过采用虚拟防火墙,结合oPC服务器分配的动态端口进行限定的方法,进行安全数采从而提升与控制系统接口的安全。结合企业现有情况,进行了过程信息集成的安全策略的部署和应用,提高了网络的安全。
In this paper, we discuss the security strategy of process information integration in petrochemical enterprises based on virtualization technology. In the petrochemical enterprise office network / production network / control network three-tier structure, will be securely embedded in the infrastructure and virtualization, the establishment of a security service management center on the production of private network security control and early warning, while the safety Delivered as a service, thus changing the traditional security model. But also through the use of virtual firewall, combined with the dynamic port oPC server to limit the method of quantitative security to enhance and control system interface security. Combined with the current situation of the enterprise, the deployment and application of the security policy of process information integration are carried out, which improves the security of the network.
