大数据平台安全威胁与防护技术研究

Research on security and protection technology of big data platform

大数据平台安全与其承载数据的安全同生共息,分布式存储和计算等新技术的应用为大数据安全带来新的挑战。首先分析大数据平台面临的安全威胁,在NIST大数据平台参考架构的基础上,提出大数据平台安全总体框架,研究目前主流大数据平台Hadoop的安全机制,分析现有安全机制存在的问题并提出解决建议。

The application of new technologies such as distributed storage and computing brings new challenges to big data security. This paper firstly analyzes the security threats that big data platforms faces. Based on the big data platform of NIST reference architecture, the overall framework of big data platform security is put forward. The security mechanism of Hadoop, the mainstream big data platform, is studied. The existing problems of the security mechanism are analyzed and suggestions are put forward.
