Shared responsibility model
In the cloud, the split of security roles between the provider and the customer depending on the type of service.
In the cloud, security is shared: the provider protects the infrastructure ("security of the cloud"), the customer remains responsible for their settings, their access and their data ("security in the cloud"). Many incidents come from a misunderstanding about this boundary, such as a storage space left open: it is not the provider's fault, but a bad setting on the customer's side.
