DSI: A New Architecture for Secure Carrier-Class Linux Clusters

An approach for distributed security architecture that supports advanced security mechanisms for current and future security needs, targeted at telecom applications running on carrier-class Linux clusters.

We presented the need for a new security approach for telecom applications running on carrier class Linux clusters. Based on our motivations to develop a coherent solution addressing the security needs of Linux carrier class clusters, we proposed a new design for a secure distributed infrastructure. We presented the main elements of this design and discussed some of the preliminary results. We believe that this design is a practical approach to enhance security for large-scale clusters with carrier-class needs.

To complete DSI, we plan to collaborate with open source initiatives and other organizations. The DSI team from Ericsson Research will be available at the Ottawa Linux Symposium for three allocated presentations on DSI. We will also be available at the IEEE Cluster Conference 2002 in Chicago. In addition, Ericsson Research will be hosting the annual Open Cluster Group meetings June 24-25 in Montreal, which will give us the opportunity to address the members of the group and get them involved with the DSI project.

We are currently preparing a web site that will be available in late June. It will provide DSI technical reports, presentations, source code and links to web sites of other contributors. We encourage people interested in DSI to contact any of the DSI team members (listed below) to receive detailed papers on the DSI architecture, strategy, source code and to discuss collaboration opportunities.
