What should this user do with the AWS account root user access keys?
Share the keys with all relevant internal users so that those users can programmatically access AWS services.
Post the keys on GitHub to provide development teams with access to AWS services.
Use the keys for access, but do not share the keys with anyone.
Delete the keys and create IAM users.
Explanations:
Sharing the root user access keys with internal users violates AWS security best practices. The root user should be reserved for specific account and billing tasks, and granting access to others can lead to unauthorized actions and security breaches.
Posting root user access keys on GitHub or any public repository is a major security risk. This exposes the keys to anyone who accesses the repository, leading to potential unauthorized access to the AWS account.
While using the keys without sharing them is better than sharing, it still goes against best practices. The root user should not be used for everyday tasks, and using the access keys can lead to security vulnerabilities.
Deleting the root user access keys and creating IAM users is the recommended practice. IAM users allow for more granular permission control, reducing the risk of accidental exposure or misuse of access. This approach enhances security by following the principle of least privilege.
My best guess is:
Delete the keys and create IAM users.
In my opinion, the answer is:
Delete the keys and create IAM users.
