Briefly describe the relationship between the enterprise or cloud consumer, as data owner, and the CSP, as data custodian, regarding data control and responsibility, within each of the three cloud service offerings: IaaS, PaaS, and SaaS.

Introduction: While an enterprise, as a data owner, has responsibility for ensuring that their data is properly protected, when data is stored with a Cloud Service Provider (CSP), the CSP assumes at least partial responsibility, if not full responsibility, in the role of data custodian. Even with divided responsibilities for data ownership and data custodianship, the data owner does not give up the need for diligence in ensuring that data is properly protected by the custodian.
