Final answer:
Access Management and Network Security are two shared controls in the AWS model, with both AWS and customers having responsibilities in managing security related to access and network configurations.
Step-by-step explanation:
The student's question relates to the AWS shared responsibility model, which differentiates the security 'of the cloud' from 'in the cloud'. In this model, certain security controls are managed by AWS (the cloud provider), while others are managed by the customer. The shared controls are those that apply to both the infrastructure layer managed by AWS and the customer layers on top.
Access Management and Network Security are two examples of shared controls within AWS. Access Management involves both the customer's management of user permissions and credentials, and AWS's responsibility to provide tools that allow the customer to do this securely. Network Security includes AWS providing a secure networking infrastructure and offering services such as VPCs, security groups, and NACLs, whereas customers must configure these correctly to manage traffic and protect their resources.
