在数据中心分布式架构部署中，Apache Hadoop 早期版本因其设计过程中对安全设计的缺失，导致在实际应用中数据中心存在安全隐患问题。通过在常见安全问题分析基础上，本文针对性地提出安全管控模型，给出了一种基于Kerberos认证机制进行数据中心加固的解决方案，提高整个数据中心的安全性。

The first version of the Apache Hadoop has caused a security problem in the architecture of data distribution, which leads to the potential hazard in applications. Based on the analysis of security problems, a managing and monitoring model is established,which is a solution of strengthening the data security. The model is on the basis of Kerberos authentication mechanism.Through the project, the security of data center can be reinforced significantly.
