A company is using AWS Identity and Access Management (IAM). Who can manage the access keys of the AWS account root user?
A
IAM users in the same account that have been granted permission
B
IAM roles in any account that have been granted permission
C
IAM users and roles that have been granted permission
D
The AWS account owner
Explanation:
Only the AWS account owner can manage the access keys of the AWS account root user. This is a critical security measure in AWS:
Root user credentials provide complete, unrestricted access to all AWS services and resources in the account
IAM users, roles, and policies cannot manage or modify root user credentials, even with administrative permissions
This separation ensures that the ultimate account ownership and control remains with the account owner
The root user should only be used for specific account-level tasks that cannot be performed by IAM users
Best Practice: Enable multi-factor authentication (MFA) for the root user and use IAM users for daily operations to enhance security.
