The Design Of Data Security And Information Security Defense Architecture In Dispatching Automation System Of State Grid

A defense project of information security for enterprises in Power System is proposed in this paper. It aims at data security of Dispatching Automation System by analyzing that of Zhengzhou State Grid, and consists of physical security, security of operation, content security and management security, which forming a characteristic defense architecture in depth from the stand point of protection prioritization. Considering functions, characteristics and significances of Dispatching Automation System in power generation, rational and secure division methods and corresponding implement projects are suggested in order to adapt to requirements of data protection of Dispatching Automation System and ensure safe, reliable and efficient operation of regional power grid.
