As a design principle, which one of the following actors is responsible for identifying and approving data security requirements in a cloud ecosystem?

The cloud broker acts as an intermediary that manages relationships between consumers and providers, but does not own the data and therefore does not have authority to identify or approve the consumer's data security requirements.

The cloud provider is responsible for implementing and maintaining security controls within their infrastructure and services, but it is not their role to define or approve the data security requirements that belong to the consumer's business context.

The cloud consumer is the organization or individual that uses cloud services and owns the data being processed or stored. As the data owner, the cloud consumer is responsible for defining, identifying, and approving data security requirements to ensure their business and compliance needs are met, even when delegating implementation to other parties like the cloud provider.

The cloud auditor independently assesses and verifies security controls and compliance against established requirements, but their role is evaluative rather than prescriptive - they do not identify or approve the requirements themselves.
