Abstract

In this paper, a novel approach for enabling Grid users to autonomously install and use custom software on demand using an image creation station is presented, while at the same time offering new security mechanisms to protect both software and data from other Grid users and external attackers. An automated dynamic firewalling mechanism enables both virtual organization and user-based network security setups. Furthermore, the Grid environment is partitioned into several zones to protect local cluster resources from compromised Grid middleware. To enable the secure integration of this Grid environment into existing business processes, an extension of BPEL is presented which allows the execution of GSI secured Grid services in combination with existing business web services. The workflow engine transparently handles proxy certificate creation and monitors proxy certificate lifetime. An implementation based on the Globus Toolkit 4, the Sun Grid Engine and the ActiveBPEL Engine is presented. A performance evaluation of the critical components of the new Grid setup is provided.
