1简介监控及数据采集系统(SCADA)是指与工业控制系统(ICS)进行通信的系统/网络,它为ICS操作员提供监控过程管理所需的数据。随着自动化技术的持续发展及其全球重要性的提升,ICS和SCADA的应用越来越广泛。早期SCADA设备主要基于电力管道和水处理管道等分布式应用,主要通过不可靠的或不稳定低带宽的或高延迟的链路来采集远程数据。虽然SCADA设备在全球范围内得到推广应用,但却面临着安全性缺失这一基本问题。 1 Introduction SCADA is the system / network that communicates with industrial control systems (ICS) and provides ICS operators with the data they need to monitor process management. With the continuous development of automation technology and its global importance, ICS and SCADA are more and more widely used. Early SCADA equipment was mainly based on distributed applications such as power and water pipelines, where remote data was collected mainly through unreliable or unstable low-bandwidth or high-latency links. Although SCADA devices are widely used worldwide, they face the basic problem of lack of security.
