Answer: Securing the company's data in transit and at rest

## Explanation Based on the AWS Shared Responsibility Model, when using Amazon Bedrock (a managed AI service), AWS is responsible for **security *of* the cloud**, which includes: - **Patching and updating Amazon Bedrock** (Option A) - AWS manages the underlying service infrastructure, including software updates and security patches for the Bedrock service itself. - **Protecting the infrastructure hosting Amazon Bedrock** (Option B) - AWS secures the physical facilities, hardware, networking, and virtualization layers that run the Bedrock service. - **Provisioning Amazon Bedrock within the company network** (Option D) - Amazon Bedrock is a fully managed AWS service provisioned within AWS infrastructure, not within a company's private network. The customer is responsible for **security *in* the cloud**, which includes: - **Securing the company's data in transit and at rest** (Option C) - This is the customer's responsibility. Customers must ensure their data is encrypted during transmission to/from Bedrock and while stored (if applicable), implement proper access controls, manage encryption keys, and follow data protection best practices for their specific use case. This aligns with AWS documentation on the Shared Responsibility Model for AI/ML services, where AWS manages the service infrastructure while customers retain responsibility for their data, configurations, and usage of the service.
