Abstract
Disaster management can be defined as the organization and management of resources and responsibilities for dealing with all humanitarian aspects of emergencies. This paper is about organizational policies when assigning responsibilities during a flood scenario. Specially, we focus on dynamic access control policies supporting delegation. Delegation is a dynamic behavior involving a user passing his access control authorizations to other users within organizations. This defines one aspect of collaboration at the organizational level. In this paper, we propose to model the delegation access control approach from the flooding business process modeling to its deployment. In doing so, we describe the delegation process, define the access control model, and implement the authorization policies within a disaster management framework.
