WS-Policy for Service Monitoring
, 2006 The paper presents a monitoring framework for WS-BPEL processes. It proposes WS-CoL (Web Service Constraint Language) as a domain-independent language, compliant with the WS-Policy framework, for specifying user requirements (constraints) on the execution of Web service compositions.

WS-Policy based Monitoring of Composite Web Services
Fifth European Conference on Web Services (ECOWS'07), 2007 MASC (Manageable and Adaptive Service Compositions)1* is a policy-based middleware for monitoring and control of composite Web services execution. The monitorable requirements are specified in the WS-Policy4MASC language that extends WS-Policy by defining new types of monitoring and control policy assertions.

WS-Policy: On Conditional and Custom Assertions
2009 IEEE International Conference on Web Services, 2009 Today, Web services play a dominant role in Enterprise Application Integration (EAI) and for realizing Service Oriented Architectures (SOA), which define the architectural foundation for various kinds of distributed applications. In many business domains, Web services must exhibit quality attributes such as robustness, security, and maintainability. As

Policy expression and checking in XACML, WS-Policies, and the jABC
Proceedings of the 2008 workshop on Testing, analysis, and verification of web services and applications, 2008 Web-based access to sensitive and confidential data is realized today via different approaches, using a variety of methods to specify and combine access control policies. In an optic of change management and evolution, a structured and flexible model is needed to handle dynamicity, particularly when handling rights in systems with many users which hold

Use Policy Frameworks to Enforce Web Service Requirements with WS-Policy
, 2004 Service-Oriented Web Services enforce specific usage requirements that clients must meet in order to use the service. Web services cannot simply respond to any request that comes in. Instead, they must be selective and can only process incoming requests that conform to their stated requirements.

Domain-Specific Processing of Policies or: WS-Policy Intersection Revisited
2009 IEEE International Conference on Web Services, 2009 We present a new approach for checking the compatibility of policy descriptions. At present, policies are widely used for explicitly expressing non-functional properties, capabilities, constraints and requirements of Web services. Policies are crucial in the negotiation phase of service discovery and selection.

From conflict of interest to separation of duties in WS-policy for Web services matchmaking process
37th Annual Hawaii International Conference on System Sciences, 2004. Proceedings of the, 2004 A Web service is defined as an autonomous unit of application logic that provides either some business functionality or information to other applications through an Internet connection. Web services are based on a set of XML standards such as simple object access protocol (SOAP), universal description discovery and integration (UDDI) and Web services ...

A Policy-Based Authorization Framework for Web Services: Integrating XGTRBAC and WS-Policy
IEEE International Conference on Web Services (ICWS 2007), 2007 This chapter describes a policy-based authorization framework to apply fine-grained access control on Web services. The framework is designed as a profile of the well-known WS-Policy specification tailored to meet the access control requirements in Web services by integrating WS-Policy with an access control policy specification language, X-GTRBAC. The

Using XML schema to improve writing, validation, and structure of WS-policies
Proceedings of the 2010 ACM Symposium on Applied Computing, 2010 WS-Policies provide a standard to describe non-functional properties of web services. These properties are usually defined by domain-specific assertions. In some domains, for example security, nested assertions are heavily used to formalize detailed properties.

Semi-automated Fuzzy MCDM and Lattice Solutions for WS-Policy Intersection
2015 IEEE World Congress on Services, 2015In order to enable a secure Business-to-Business (B2B) interaction between web services, it is essential to negotiate a common security policy by computing the policy intersection according to the web service (WS)-policy framework. For this purpose, both policies are transformed into Disjunctive Normal Form (DNF).
