Aniketos-SSVV (Aniketos Security Service Validation and Verification) provides a series of modules that work together to validate the security properties of a Web service composition. The package is given a selection of service compositions (provided in the form of BPMN processes with Web services bound to the service tasks), along with the security policy to be fulfilled. The package then performs various checks on the services to establish whether each composition satisfies the policy, returning an ordered list (ordered in terms of security) of the services that do. It forms part of the larger Aniketos project comprised of four packages in total.
