Hadoop作为一种开源的基础云计算框架,在企业界逐步得到了有效的应用,但其安全机制的薄弱已成为阻碍其发展的主要问题之一。文中首先归纳了传统网络的安全问题以及安全机制,分析了云计算的安全问题,然后通过对Hadoop工作模式的描述,提出了Hadoop的安全需求,最后通过对Hadoop当前安全机制的研究,分析了其中的安全隐患,并提出了相应的解决办法,为Hadoop新安全需求的企业应用提供了技术支持。 As an open-source basic cloud computing framework, Hadoop has been gradually applied in the business community. However, the weakness of its security mechanism has become one of the major obstacles to its development. The paper first summarizes the security and security mechanisms of traditional networks, analyzes the security issues of cloud computing, and then puts forward the security requirements of Hadoop by describing the working mode of Hadoop. Finally, by analyzing the current security mechanism of Hadoop, Security risks, and put forward the corresponding solutions for Hadoop new security needs of the enterprise applications provide technical support.
