The power terminal network has the characteristics of a large number of nodes, various types, and complex network topology. After the power terminal network is attacked, the impact of power terminals in different business scenarios is also different. Traditional impact assessment methods based on network traffic or power system operation rules are difficult to achieve comprehensive attack impact analysis. In this paper, from the three levels of terminal security itself, terminal network security and terminal business application security, it constructs quantitative indicators for analyzing the impact of power terminals after being attacked, so as to determine the depth and breadth of the impact of the attack on the power terminal network, and provide the next defense measures with realistic basis.

To solve the problem of big data security and privacy protection, and expound the concept of cloud computing, big data and the relationship between them, the existing security and privacy protection method characteristic and problems were studied. A reference model is proposed which is based on cloud platform. In this model the physical level, data layer, interface layer and application layer step by step in to implement the system security risk early warning and threat perception, this provides an effective solution for the research of big data security. At the same time, a future research direction that uses the blockchain to solve cloud security and privacy protection is also pointed out.
