The need for Shared Situational Awareness (SSA) in accomplishing joint missions by coalition militaries, law enforcement, the intelligence community, and the private sector creates a unique challenge to providing access control. In this thesis we investigate the capabilities and limitations of Role-Based Access Control (RBAC) to control the dissemination of SSA in a coalition environment. Our case study is that of controlling access to SSA in the Maritime Domain Awareness (MDA) environment. MDA exemplifies both rapid change in membership of coalitions and the roles of coalition participants. We explore the access policy and roles played by the participants in the MDA environment, in addition to the characteristics of those roles. We make use of feasible scenarios to provide us with a base for applying models to the situation. The models that are applied to the scenario provide the formal methods that prove that RBAC policies and derivatives such as Distributed Role Based Access Control (DRBAC), Coalition Based Access Control (CBAC) and Temporal Role Based Access Control (TRBAC) can be used in conjunction with the Information Broker (IB) concept to provide adequate access control policies.
