In the AWS shared responsibility model, what is the customer's responsibility?

In the AWS shared responsibility model, the customer is responsible for managing data security and user access. This responsibility encompasses several crucial aspects of cloud security, including configuring access permissions, encrypting sensitive data, and regularly managing user roles and identities.

Customers must ensure that their applications and data are protected from unauthorized access and that appropriate measures are in place to safeguard sensitive information. This includes implementing security best practices, such as using IAM (Identity and Access Management) for access control and regularly auditing access logs to track who is accessing resources within their AWS environment.

By understanding that they are responsible for these aspects, customers can effectively safeguard their data in the cloud while relying on AWS to manage the security of the underlying cloud infrastructure, including physical hardware, network, and virtualization layers. This division of responsibility is fundamental to maintaining security in a cloud environment.
