IAM users in AWS should receive permissions only through groups to enforce better security and manageability. This practice can ensure that users inherit permissions from groups, which are easier to manage and update than individual user permissions. By assigning permissions to groups instead of individual users, it becomes easier to add or remove user permissions as needed. It also ensures that permissions are consistent across users with similar job functions or roles. Additionally, this approach can reduce the risk of unauthorized access due to human error or rogue insiders. Therefore, it is recommended to ensure that IAM users receive permissions only through groups.
To ensure IAM users receive permissions only through groups, you can follow these remediation steps:
It's important to note that IAM users should not have any permissions assigned directly to them, and should only receive permissions through groups. This ensures that access to resources is properly managed and easily auditable. Regular monitoring and review of permissions assigned to IAM users and groups should also be conducted to ensure that they are still necessary and appropriate.
