A first step towards security policy compliance of connectors

Abstract

Connectors have emerged as a powerful concept for composition and coordination of concurrent activities encapsulated as components and services. The widespread use of connectors in service-oriented applications is hindered by the lack of adequate security support. A security policy defines a set of security requirements that correspond to permissions, prohibitions and obligations to some executions when some contextual conditions are satisfied. In this paper, we propose the use of a scenario-based visual notation, called Policy Sequence Chart (PSC), for specifying security policies, and investigate an approach in which connectors are compliant with the security policies. © 2010 Springer.
