The Aniketos project aims to help establish and maintain trustworthy and secure behavior in dynamically changing environments of composite services. It develops methods and tool support for the design and runtime composition of secure dynamic services. The project addresses challenges of composite security where individual services may be trustworthy but their composition is not clear. It proposes expressing security and trustworthiness requirements through models and generating security agreements. The Aniketos platform supports security definition, evaluation, monitoring, and adaptation for composite services.
