Abstract
Even though enterprises increasingly recognize the benefits of cloud computing, many are still reluctant using cloud-based applications or services like customer relationship management (CRM) solutions due to security and privacy concerns. This article aims at defining a roadmap to derive a holistic framework providing data privacy and security by design in the context of cloud-based multi-tenant CRM systems. As a CRM system developed for SMEs CAS PIA serves as an example for typically occurring data structures and use cases including the innovative concept of user-defined security levels for different data types. We present a scenario and requirements analysis for motivating the need for a suitable user-context-specific security concept and a data and privacy preserving framework.
