In the Infrastructure-as-a-Service (IaaS) cloud computing service model, the cloud service provider is

responsible for managing the infrastructure, which includes the operating system, hypervisor,

physical infrastructure, and network security. At the same time, the customer is responsible for

managing user access, applications, and data security.

Cloud Service Provider Responsibilities: In IaaS, the provider is responsible for the physical hardware,

storage, and networking capabilities. They also ensure the virtualization layer or hypervisor is secure.

Customer Responsibilities: The customer, on the other hand, manages the operating system,

middleware, runtime, applications, and data. This includes securing user access and application-level

security measures.

Flexibility and Control: IaaS offers customers a high degree of flexibility and control over their

environments, allowing them to install any required platforms or applications.

Examples of IaaS: Services such as Amazon EC2, Google Compute Engine, and Microsoft Azure Virtual

Machines are examples of IaaS offerings.

Reference:

The shared responsibility model is a fundamental principle in cloud computing that outlines the

security obligations of the cloud service provider and the customer to ensure accountability and

security in the cloud. In the IaaS model, while the cloud provider ensures the infrastructure is secure,

the customer must secure the components they manage.
