Modeling security concerns in service-oriented architectures
Business stakeholders depend on the IT organization to provide solutions to their business requirements. For both financial and market-driven reasons, stakeholders want to shorten the investment in time and money it takes to deliver IT solutions. They also want to increase the value they derive from IT solutions by maximizing the requirements coverage each software project provides. Because so many of those projects today involve Web services, it is very important that we have better tools and techniques for the rapid and successful implementation of those business requirements using SOA. We consider modeling to be especially important because of its ability to separate concerns and present a unified view of those concerns. Security in service implementations is a major concern because many applications operate across organizational boundaries. The purpose of this paper is to provide a set of primitive modeling elements that allow the business stakeholders to specify the intent of security within the requirements process.
