Reflections on the Construction of Cyber Security Range in Power Information System

With the continuous development of the Internet in the energy field, the architecture of the power information network system is also evolving, which brings serious security problems to the power information network. To cope with the increasingly complex network security situations, strengthen the protection of power critical information infrastructure, improve network security protection level throughout the life cycles of the power industry research and development for security, security detection, offense and defense and vulnerability mining, emergency response capabilities and production control systems, management information systems, this paper proposes using network virtualization technology and cloud computing technology to build a cyber security offense and defense simulation range in the power industry. The network security range is an important infrastructure for personnel training which can provide a good management and practical environment for offensive and defensive drills and training, thereby to improve the overall information security capabilities of the power industry.
