Today, there is a huge amount of security services that can be used to implement different security requirements in Web Service based systems. For example, identity management services are required for authentication and authorization whereas message logging services are necessary to achieve non-repudiation.

Service-oriented Architectures support the provision, discovery, and usage of services in different application contexts. The Web Service specifications provide 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 expressed as security policies (e...
Cloud computing enables the provisioning of dynamically scalable resources as a service. Next to cloud computing, the paradigm of Service-oriented Architectures emerged to facilitate the provisioning of functionality as services. While both concepts are complementary, their combination enables the flexible provisioning and consumption of independently scalable services. These approaches come along...
