Service oriented modeling of communication infastructure for assurance
Albin Zuccato, Bernard S. Marquet, Serge Papillon, Magnus Aldén · 2006
To be able to achieve security assurance for services, which run on large and complex communication infrastructures, support tools are needed. Such tools need a representations of the infrastructure that enables and provides security assurance. In this paper we suggest an assurance modeling profile for UML 2.0. The profile contains stereotypes that define assurance-relevant object types as observed and unobserved assurance-relevant infrastructure items or metrics. In addition, the model defines information relevant for the aggregation of assurance, to allow an assurance value for a service to be derived from its underlying infrastructure. Our modeling approach starts from a service-oriented flow model and stepwise refines the topology and hierarchy view of the infrastructure involved in the service. To validate our approach we model a voice-over-IP service and show how the approach satisfies initially stated requirements
