Explanation

In the AWS Shared Responsibility Model:

• Configuration management (Correct Answer): This is a shared responsibility where AWS manages the configuration of the underlying infrastructure, while customers are responsible for configuring their own applications, operating systems, and services.

• Physical and environmental controls: This is solely AWS's responsibility - AWS manages the physical security of data centers, power, cooling, and environmental controls.

• Data integrity authentication: This is primarily the customer's responsibility - customers are responsible for implementing proper data validation, encryption, and authentication mechanisms for their applications.

• Identity and access management: This is a shared responsibility where AWS provides IAM services and tools, but customers are responsible for managing user access, permissions, and policies within their AWS accounts.

The shared responsibility model divides security responsibilities between AWS (security of the cloud) and customers (security in the cloud). Configuration management falls into the shared category because AWS manages the infrastructure configuration, while customers manage their application and service configurations.
