Which of the following is a responsibility of AWS in the shared responsibility model?

In the shared responsibility model of AWS, the distinction between responsibilities is clearly outlined between AWS and the customer. One primary responsibility of AWS is the physical security of its infrastructure, which includes restricting access to data centers. This involves securing physical access to the servers, networking hardware, and other components that make up the cloud environment. AWS ensures that only authorized personnel can enter these facilities, thereby safeguarding the cloud infrastructure against physical threats.

This focus on physical and environmental security is critical since it establishes a trust foundation for customers utilizing AWS services. AWS is responsible for the security of the cloud infrastructure itself, including server maintenance, hardware repair, and network protections, allowing customers to concentrate on securing their applications and managing their data within that infrastructure.

In contrast, configuring user permissions, patching application software, and data classification and management fall under the purview of AWS customers. These tasks require customer involvement as they directly relate to how customers manage their own applications and data within the AWS environment.
