The key contributions of this thesis are threefold: firstly, a modelling language that expresses dynamic access control policies with compound actions that update multiple variables; secondly, a knowledge-based verification algorithm that verifies properties over an access control policy that has compound actions; and finally, an automated tool, called X-Policy, which implements the algorithm. This research enables us to model and verify access control policies for web-based collaborative systems. We model and analyse a number of conference management systems and their security properties. We propose the appropriate modifications to rectify the policies when possible. Ultimately, this research will allow us to model and verify more systems and help avoid the current situation. 2012-07 2012-03 graduation eng author unchecked This unpublished thesis/dissertation is copyright of the author and/or third parties.
