In the shared responsibility model for cloud computing, which task is the customer responsible for?

• A. Managing physical security of data centers
• B. Securing data, workloads, and access
• C. Providing cloud infrastructure hardware
• D. Securing the cloud environment

Answer: (B)

The shared responsibility model splits security duties between the cloud provider and the customer. The customer is responsible for securing what they bring into the cloud: their data, the workloads they run, and who can access them—this includes implementing access controls, encryption, and proper configuration of their applications. The cloud provider handles the foundation: physical security of data centers, the hardware and virtualization, and overall protection of the cloud environment itself. So, securing data, workloads, and access is the customer’s task, while the other items are handled by the provider.
