The paper by Gabriela Gheorghe, Stephan Neuhaus and Bruno Crispo from the University of Trento was accepted and published in the proceedings of the Annual IFIP WG 11.11 International Conference on Trust Management that took place on June 16 – 18 this year in Morioka, Iwate (Japan). 

In their paper authors propose xESB, an enhanced version of an Enterprise Message Bus (ESB), where they monitor and enforce preventive and reactive policies, both for access control and usage control policies, and both inside one domain and between domains. In addition, introduce indicators that help SOA administrators assess the effectiveness of their policies. Their performance measurements show that policy enforcement at the ESB level comes with only moderate penalties. 

The work published in the above mentioned paper has partially received funding from the 7^th Framework Programme under the MASTER project.
