With increasingly distributed computing systems, the management task of controlling access to shared resources becomes more and more complicated. Policy based access control systems may provide a solution to this problem, but the issue then becomes one of how to easily specify access control policies. We have designed and implemented a user interface that enables novice users to author their own access control policies using a controlled natural language (CNL) interface. With this interface, users are able to author their policies by typing sentences in a sub set of the English language. The sentences are then parsed and output as a machine readable policy, ready for automatic enforcement by a policy decision point (PDP). In this paper we describe the details of the design and implementation of this CNL interface, along with a summary of the user evaluation.
