Abstract: By analyzing the construction status of security classified protection for electric information systems and the security demand of smart grid, this paper proposes an information security protection model for smart grid based on classified protection. According to the characteristics of smart grid, the presented model describes possible information security protections from aspects of physical, terminal, boundary, network, host, application and data security. With the aim of enhancing the information security defense capability of smart grid, the proposed model can be useful and practical during the construction of smart grid information security facilities.
