Analysis of Computer Network Information Security in the Era of Big Data

摘要

In the era of big data, computer network has brought great convenience to people's work and life, but also brought security risks in information. Therefore, the analysis of network information security plays an important role in the development and use of computer network. Under the background of big data, this paper puts forward three research hypotheses from three different factors of technology, personnel and environment, and constructs the evaluation model of computer network information security. By using the structural equation with good adaptability to test the research hypothesis, it is found that the correlation coefficients of the research hypothesis have no significant difference, and the model hypothesis is all valid. In this paper, entropy method is also introduced, and an index weight model is proposed. Experiments show that the index weight model based on entropy method is reasonable.
