Abstract: Grade protection is the basic system of national cyber security. Industrial control system is widely used in many industries, such as power, oil and gas, water conservancy, railway, tobacco, iron and steel, nonferrous metal and so on. Industrial control system is an important kind of protection objects in grade protection. This paper explains the concept, development history, classification and application fields of industrial control systems, introduces the selection criteria, evaluation index and evaluation processes of industrial control system evaluation objects according to different standards and different angles, and gives how to determine the assessment targets from the guidelines of evaluation process. This paper introduces how to determine the evaluation object and index of industrial control system according to multiple grade protection standards step by step from complexity to simplicity, from whole to concrete, which has typical guiding significance for carrying out the evaluation of industrial control system.

Key words: industrial control system, grade protection, information security testing technology, evaluation object, evaluation index
