There is a dilemma for all tenants of a public or private cloud: Scope. For the tenant, they want everything to be in scope. For the Cloud Service Provider (CSP) they want to limit scope to the bare minimum. What does it mean for a Cloud to be ‘PCI Compliant’ and why is this a requirement for some tenants. The real issue, is what is in scope for PCI-DSS while your data is in the cloud and how can you as the tenant meet those requirements.
I have written about the Public Cloud Reality and the need to bring your own security, monitoring, support. This was reinforced by Dave Asprey of Trend Micro at the last Cloud Security Alliance Summit held at this years RSA Conference. The gist of Dave Asprey’s talk was that YOU are responsible for the security of your data, not the cloud service provider.
