Evidence-Based Security and Privacy Assurance in Cloud Ecosystems

This paper is concerned with the problem of security and privacy assurance in cloud ecosystems. Different controls are deployed in order to guarantee security and privacy across cloud ecosystems. It is yet challenging to assess their effectiveness in operation. Therefore, it is necessary to devise methodologies and technologies for providing assurance of whether security and privacy controls are effective and appropriate for specific cloud ecosystems. This paper discusses the rationale and requirements for evidence-based security and privacy assurance. It also discusses the underlining mechanisms shaping a software defined storage system for gathering evidence drawn from a cloud ecosystem. It explains such requirements and mechanisms in the context of a sample use case. In conclusion, it provides insights for evidence-based security and privacy assurance of cloud ecosystems.
