摘　　要：现有安全机制不能满足Linux集群的需要。本文通过对Linux集群的分布式安全进行研究,以进程作为基本安全实体,将强制访问控制机制由结点级扩展到整个集群,提出了一个在集群内实现安全区的分布式安全模型,用LMBehch3.0进行了测试,给出了性能比较结果。Existing security mechanism can not satisfy the need of Linux cluster. After studying the distributed security for Linux clusters,an extension to Mandatory Access Control（MAC） mechanism used at node level to the whole cluster with processes as basic security entities is given, a new distributed security model that implements security zones inside the cluster is presented. Tested using LMBench3.0, the comparison of performances between a LSM patched kernel without any security mechanism implementeda nd a kernel supporting DSI distributed security services is shown.
