Research on Cyber Security Defense and Protection in Power Industry

The power information network is a significant part of national key information infrastructure, as well as the core promoting force to guarantee the strategic development of energy internet. Due to its correlative characteristics in industrial control network, the internet and IoT, superadd a large of nodes and data sensitivity, the evolving network attack technology has put forward new requirements and challenges to its security protection system, which also hinders the overall interconnecting and interworking of energy internet to a certain extent. In order to improve the network security capability of full-service power network under the energy internet environment, a power information security framework based on cloud service was proposed to improve the safety and reliability, build an end-to-end electronic authentication mechanism and security management mode of strong data interworking, finally realize the life cycle data protection, trusted identity management and reliable electronic voucher application, meet the rapid development of the energy internet and escort the new digital economic of the power industry.
