To face the changes of network security situation in industrial control field of power industry and the security needs of important information system and meet the requirements for special network security tools, we carry out the top design work of network attack and defense simulation range in power industry and build a network security test simulation platform which include the power monitoring system, an important information system which similar to the real production environment. In this paper, we list recent developments concerning the construction of network security attack and defense range system in power monitoring system at home and abroad. According to the overall scheme of power monitoring system for security. We found a highly simulated range environment containing all of these parts–sending, changing, matching, usage, scheduling, information, design the network security attack and defense platform architecture and ensure the safe, reliable and stable operation of the power system effectively.
