【摘要】：在过去几年几个监控系统已经实施并且建立,但主要的问题仍然存在,如高成本的系统、不安全的连接和速低速的通信。本文研究的目是建立低成本完善的大型分布式系统模型,它将是足够快速和安全的实时管理系统,用以解决安全报警问题。过去两年,在阿拉斯加有一个科学研究小组对12KV变电站分布式系统的安全性进行了研究,但是到目前没有得到预期结果。本文介绍了SCADA控制系统、外部威胁、漏洞和改进方法的研究。此外,还研究了在SCADA环境中不同探测方法的有效性,并最终建立了网络监测原型。给出了一个大型分布式网络的实施方案,介绍了创建SCADA系统的模型和方法,并给出了建立分布式网络SCADA系统的必要设备和系统模型,进而说明了必要的技术和设备特点、功能以及系统所使用的协议(Modbus、DNP3、DeviceNet标准、Control Net等)和组件。描述了12kV变电站SCADA系统网络监测的安全性,SCADA在电力系统中的安全威胁以及应用遗传算法来检测SCADA分布系统的漏洞等技术。最后,证明了本文所提出的测量方法对网络研究人员和安全专业人员收集SCADA系统信息是有帮助的。
[Abstract]:Several monitoring systems have been implemented and established in the past few years, but major problems remain, such as high-cost systems, insecure connections and fast and low-speed communications. The purpose of this paper is to establish a low-cost and perfect large-scale distributed system model. It will be a fast and safe real-time management system to solve the security alarm problem. In the past two years, a scientific research team in Alaska has studied the security of distributed systems in 12KV substations, but so far no expected results have been obtained. This paper introduces the research of SCADA control system, external threats, vulnerabilities and improvement methods. In addition, the effectiveness of different detection methods in SCADA environment is studied, and the prototype of network monitoring is established. This paper presents an implementation scheme of a large-scale distributed network, introduces the model and method of creating a SCADA system, and presents the necessary equipment and system model for establishing a distributed network SCADA system, and then explains the necessary technology and equipment characteristics. Functions and the protocols used by the system (Modbus,DNP3,DeviceNet standard, Control Net, etc.) and components. This paper describes the security of network monitoring of SCADA system in 12kV substation, the security threat of SCADA in power system, and the application of genetic algorithm to detect the vulnerability of SCADA distribution system. Finally, it is proved that the measurement method proposed in this paper is helpful for network researchers and security professionals to collect SCADA system information.
