Aniketos is about establishing and maintaining trustworthiness and secure behaviour in a constantly changing service environment. The project aligns existing and develops new technology, methods, tools and security services that support the design-time creation and run-time dynamic behaviour of composite services, addressing service developers, service providers and service end users. Aniketos provides methods for analysing, solving, and sharing information on how new threats and vulnerabilities can be mitigated. The project constructs a platform for creating and maintaining secure and trusted composite services. Specifications, best practices, standards and certification work related to security and trust of composite services are promoted for inclusion in European reference architectures. Our approach to achieving trustworthiness and security of adaptive services takes account of socio-technical aspects as well as basic technical issues.
