Expressing and reasoning about conflicting norms in cybersecurity: poster.

Secure collaboration requires the collaborating parties to apply the right policies for their interaction. We adopt a notion of conditional, directed norms as a way to capture the standards of correctness for a collaboration. How can we handle conflicting norms? We describe an approach based on knowledge of what norm dominates what norm in what situation. Our approach adapts answer-set programming to compute stable sets of norms with respect to their computed conflicts and dominance. It assesses agent compliance with respect to those stable sets. We demonstrate our approach on a healthcare scenario.
