Research of Distributed Security for Clusters
Cheng Dian-qin · Modern Computer · 2006
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 communications. Existing distributed security infrastructure and the distributed security mechanism in a cluster security monitoring tool are introduced.
