- 5. Security Risks &Potential Opportunities
- 6. What are your main concerns in your approach to Cloud Computing?Source: ENISA An SME Perspective on Cloud, 2009

- 8. In Brief Data Trust Boundary Data Security Identity and Access Management (IAM) Privacy Considerations Information Assurance Concerns CSA Security Guidance v2.1
- 9. Trust Boundary Trust Boundaries have changed with cloud computing Note: Different cloud providers might have different trust boundaries Data barriers Need for transparency Governance Enterprise Risk Management Compliance and AuditSource: Cloud Security and Privacy Tim Mather

Data Security Providers data collection efforts and monitoring of such Use of encryption Data in Transit Data at Rest Key management is a significant issue Data lineage Data provenance Data remanence Information Lifecycle Management Encryption and Key Management Compliance and AuditSource: Cloud Security and Privacy Tim Mather

- 14. Potential Questions from the Clients Does the provider hold certifications such as ISO 27001/2, SAS 70? If yes, what is the scope of the certifications? Does the provider share with the physical location of the servers? To what extent are storage, memory and other data traces erased from the machines before being reallocated to a different customer? i.e. Data remanence Does the provider support the data classification scheme used? How does the provider guarantee isolation of resources from other customers? Learn from the Cloud service provider (CSP) about key management. Who handles and manages the key? How does the CSP report on its security management? Does the CSP have an analytics tool to monitor your cloud? What are the CSPs control monitoring processes? Is your data bound by local jurisdiction?
