A Pattern-Driven Generation of Security Policies for Service-Oriented Architectures
Service-Oriented Architectures (SOA) supports the provision, discovery, and usage of services in different application contexts. The web service specifications pro-vide a technical foundation to implement this paradigm. Moreover, mechanisms are provided to face the new security challenges raised by SOA. To enable the seamless usage of services, security requirements can be ex-pressed as security policies (e.g. WS-Policy and WS-SecurityPolicy) that enable the negotiation of these requirements between clients and services. However, the codification of security policies is a difficult and error-prone task due to the complexity of the web service specifications.
