Study on Classification of Data in Power Industry

Abstract

The electric power industry is an important energy industry, and is related to economy and people's livelihood, so the data security issues is very important. Today is the era of cloud and big data, but the cloud environment and huge amounts of data cause the problem of data security, including the illegal acquisition and leakage of information and so on. In order to ensure data security, it’s necessary to classify the data and protect the key data according to the different needs. According to the domestic standard regulations and the internal norms of the state grid, the data which including user data and enterprise data is classified according to the subject. Data classification is divided into low-impact, medium-impact, and high-impact levels based on security objectives (confidentiality, integrity, availability).It is important for defining boundaries of data sharing and data open to classify data, protect the important and sensitive data in electric power industry and to improve the data security and access control of cloud platform.
