Implementation of Security Technology of Cloud Computing Platform Based on Hadoop

Abstract

In recent years, cloud computing has been widely researched and applied, and the key factor that affects the popularity or acceptance of cloud computing is the security of cloud computing. As an open source basic cloud computing framework, Hadoop has become more and more widely used in the corporate world. Research on the security technology of cloud computing platform based on Hadoop is of great significance for better research on cloud computing security and promotion of Hadoop. The purpose of this paper is to study the security technology of cloud computing platform based on Hadoop. This article first summarizes the basic theories of cloud computing security and the core framework of Hadoop, and then researches and designs the cloud computing file management system based on Hadoop, and conducts research and analysis on its security solutions. This paper systematically expounds the architecture design, function design and detailed design of the cloud computing file management system, and uses comparative analysis and observation methods to study the subject of this paper. Experimental research shows that the choice of k (nearest neighbor range) has little effect on the detection rate. It is inferred that the detection rate is mainly affected by the length of the subsequence. However, as the value of k increases, the detection rate decreases slightly, but the false detection rate is proportional to the value of k, that is, the detection effect is relatively reduced.
