Tao, Y., Lei, Z., Ruxiang, P..  2018.  Fine-Grained Big Data Security Method Based on Zero Trust Model. 2018 IEEE 24th International Conference on Parallel and Distributed Systems (ICPADS). :1040-1045.

With the rapid development of big data technology, the requirement of data processing capacity and efficiency result in failure of a number of legacy security technologies, especially in the data security domain. Data security risks became extremely important for big data usage. We introduced a novel method to preform big data security control, which comprises three steps, namely, user context recognition based on zero trust, fine-grained data access authentication control, and data access audit based on full network traffic to recognize and intercept risky data access in big data environment. Experiments conducted on the fine-grained big data security method based on the zero trust model of drug-related information analysis system demonstrated that this method can identify the majority of data security risks.
