Abstract:Under the intelligent development of energy Internet and power grids, various new power grid services and work scenarios have a increased demand for the access to dispatching master station system. It is necessary to standardize the authority configuration of dispatching terminals, strengthen the safety audit of operation process, improve the management system and technical means, which can effectively prevent security attacks and improve risk prevention level in response to extreme situations. By analyzing the current status of the use of KVM extension technology for dispatching terminals, a regulatory terminal security control technology based on cloud computing and biological multi-factor authentication is proposed. According to the business scenarios of power grid dispatching automation, the proposed technology integrates software technologies such as computing virtualization, network virtualization, storage virtualization, operation and maintenance monitoring and management, and cloud desktop business process delivery to form a standardized regulatory terminal security management and control system solution.
