IAM Users Should Be in at Least One Group Rule

Rule/Policy Description:

Troubleshooting Steps (if applicable):

2. 1.
   Verify IAM user settings: Check if the user is currently not associated with any group.
4. 2.
   Assign the user to a group: Find the appropriate group that aligns with the user's job responsibilities and requirements. For example, if the user is responsible for managing EC2 instances, assign them to the "EC2 Management" group.
6. 3.
   Verify group membership: Validate that the user is successfully added to the assigned group.
8. 4.
   Test access: Ensure the IAM user can access the required resources and perform necessary actions within the assigned group's permissions.
10. 5.
    Repeat steps for all remaining IAM users without group assignments.

Necessary Code (if applicable):

aws iam add-user-to-group --user-name <IAM_USERNAME> --group-name <GROUP_NAME>

<IAM_USERNAME>

<GROUP_NAME>
