In this paper, the authors present a survey on security and privacy issues in big data and NoSQL. Due to the high volume, velocity and variety of big data, security and privacy issues are different in such streaming data infrastructures with diverse data format. Therefore, traditional security models have difficulties in dealing with such large scale data. In this paper, they present some security issues in big data and highlight the security and privacy challenges in big data infrastructures and NoSQL databases.
