Which of the following security responsibilities are shared between an organization and its cloud service provider in an IaaS cloud environment?

In an Infrastructure as a Service (IaaS) cloud environment, security responsibilities are divided between the cloud service provider and the organization using the service. Infrastructure security is primarily a shared responsibility because the provider secures the physical infrastructure, including data centers and networking hardware. However, the organization is responsible for securing its own virtual instances, storage, and configurations within that infrastructure. This collaborative approach ensures that both parties contribute to a robust security posture.

In this model, while the cloud service provider manages the foundational physical security controls, the organization must implement and maintain security measures for the resources they deploy, making infrastructure security a clear point of shared responsibility. This concept emphasizes the need for organizations to understand their role in securing not just the system but also how they utilize the infrastructure that the provider offers.
