Answer: Manage database access permissions.

## Explanation In the AWS shared responsibility model: - **AWS is responsible for security OF the cloud** - This includes patching the operating system, provisioning hosts, and securing the underlying infrastructure for managed services like DynamoDB. - **The customer is responsible for security IN the cloud** - This includes managing database access permissions, configuring security groups, and controlling who can access their data. For Amazon DynamoDB (a fully managed NoSQL database service): - AWS handles: OS patching, host provisioning, infrastructure security - Customer handles: Database access permissions, IAM policies, data encryption settings Therefore, managing database access permissions is the company's responsibility.
