A New Distributed Security Model for Linux Clusters
Makan Pourzandi, Open Systems Lab, Ericsson Research
With the increasing use of clusters in different domains,
efficient and flexible security has now become an essential
requirement for clusters, though many security
mechanisms exist, there is a need to develop more flexible
and coherent security mechanisms for large distributed
In this paper, we present the need for a unified cluster
wide security space for large distributed applications.
Based on these needs, we propose a new security
model that implements security zones inside the cluster.
The model is an extension to Mandatory Access Control
(MAC) mechanisms used at node level to the whole
cluster with processes as basic security entities.
We designed this model with clustered Linux servers
running carrier-grade applications in mind but this
model can be used in any domain that needs Linux clusters
running large distributed applications continuously
with no interruptions. We prove the feasibility of this
approach through an open source implementation of the
