The IEEE International Symposium on Policies for Distributed Systems and Networks (POLICY 2012) is the premier conference on the topic of using policies (business rules) to manage communications and distributed systems.

TSSG researchers presented a paper entitled “On the performance of access control policy evaluation”. The paper was motivated by a discussion between Leigh Griffin and Bernard Butler in May 2011 at the IEEE IM conference held at TCD (jointly hosted by TSSG). Leigh described his research on group formation and management and the important sub-topic of managing access to digital resources. Bernard described his research on access control system design and modelling how this affects the performance of policy-based access control. As the collaboration proceeded, Leigh recast access control policies in a new language and prototyped some ideas for improving Policy Decision Point performance by drawing upon recent developments in the development of scalable web services. Bernard contributed an extension of his service time measurement testbed (STACS), experimental setup and performed a comprehensive performance analysis of Leigh’s prototype. Other authors, all TSSG researchers, contributed advice and guidance based on their areas of expertise.

The resulting paper which can be viewed here, benefited from collaboration between the authors and the reviewers agreed that it presented a compelling case in favour of novel ways of specifying access control policies and of implementing Policy Decision Points.

Bernard presented the paper at the POLICY 2012 conference in the University of North Carolina, Chapel Hill, USA, 16-18 July. The presentation sparked discussions with other researchers at the conference, notably those participating in the FP7 Webinos project.
