An Industrial Control Safety Situation Assessment Based on Standard Deviation

With the rapid development of information technology, and the integration of informationization and industrialization, industrial control systems access the Internet in various ways, which changes the original characteristics of these systems, including closure and specialization. However, many information security issues also appear in industrial control systems. In view of the status of industrial control safety, the multi-attribution evaluation based security situation assessment on industry control has been proposed in this paper, and this approach has also been applied to the evaluation and prediction on the network security situation of China's networked power system, in order to find the potential threat information. Meanwhile, facing with the threat, some technical methods are put forward to give early warnings effectively.
