主机监控系统的分布式控制研究

Research of Distributed Control of Host Monitoring System

研究了传统的主机监控系统,为了使主机监控系统能应用于大型关联主机群环境,对主机监控系统实现分布式管理。提出了一种新型的基于树形安全域的分布式管理模型,给出了了该模型的形式化定义,并分析了该模型的优点,最后描述基于树形安全域的分布式控制模型节点管理服务、分布安全策略访问管理、命令交互协议、主控主机故障恢复问题。在大型关联主机群分布式主机监控系统中,该模型较好地解决了分布策略的统一灵活管理的问题。

In order to apply host monitor system in large scale host system and realize distributed control,a lot of research on traditional host monitoring system is presented.A new concept of safety domain based on tree architecture and a distributed control pattern based on security domain is introduced.The formal definition and the benefits using the model are given.At last,the key problem using the model such as security node management,security policy management,command interaction and implementation interface are analysed.The resuls show that it realizes unified management of distributed policy in distributed host monitoring system.
