Abstract

With the rapid development of big data and cloud computing technology, the problem of data security has become increasingly prominent, and has become one of the key factors restricting its wide application. This paper aims to deeply analyze the status quo, main problems and countermeasures of data security in big data cloud computing environment, in order to provide reference for research and practice in related fields. First of all, this paper summarizes the basic concepts of big data and cloud computing, expounds the basic theory of data security, and analyzes the particularity and challenges of data security in the environment of big data cloud computing. Secondly, by summarizing the data security practices in the current big data cloud computing environment, this paper discusses the development of data security technologies and standards, as well as the sorting out of data security policies and regulations and the promotion and education of data security awareness. Thirdly, this paper discusses in detail the risks of data leakage and theft, the challenges of data privacy protection, the threats to data integrity and availability, and the security issues of cross-domain data sharing. Finally, countermeasures and suggestions are put forward to strengthen the research and development of data security technology and standards, improve the data security policy and regulation system, enhance the whole society's data security awareness and ability, and build a cross-domain data security sharing mechanism. This paper not only reveals the complexity and urgency of data security under the big data cloud computing environment, but also provides useful ideas and directions for promoting the healthy development of data security field.
