According to the AWS shared responsibility model, which of the following is an AWS responsibility?

The shared responsibility model dictates that AWS is responsible for "security of the Cloud," while the customer is responsible for "security in the Cloud." Maintaining the physical hardware of the infrastructure falls under AWS's responsibility for security of the Cloud, as it involves the underlying global infrastructure that supports all AWS services. Configuring identity and access management for applications, managing encryption choices for data, and configuring security groups for Amazon EC2 instances are all responsibilities of the customer (security in the Cloud). These tasks involve how customers use and secure their data and applications within the AWS environment.
