集群分布式安全探讨

Research of Distributed Security for Clusters

集群越来越多地暴露给来自公网的攻击者,有效灵活地安全管理机制成为现今集群的本质需求。本文分析集群面临的威协与挑战,从分布式认证、分布式访问控制、分布式监测、分布式安全通信等方面给出了分布式服务的结构性方法,介绍了现存分布式安全基础设施和一个集群安全监测工具中的分布安全机制。

Clusters are exposed to an increasing number of attacks coming from public networks. Mechanisms for efficiently and flexibly managing security have now become an essential requirement for clusters. After analyzing the threats and challenges that clusters faced, structured approaches of distributed services are presented from distributed authentication, distributed access control, distributed monitoring, and distributed security communieations. Existing distributed security infrastructure and the distributed security mechanism in a cluster security monitoring tool are introduced.
