IAM Users Should Be in at Least One Group Rule
This rule ensures that IAM users are assigned to at least one group for proper access control.
| Rule | IAM users should be in at least one group |
| Framework | NIST 800-53 Revision 4 |
| Severity | ✔ High |
Rule Description:
IAM users should be assigned to at least one group for compliance with NIST 800-53 Revision 4. Assigning IAM users to groups allows for easier management of permissions and access control within an AWS account. This rule ensures that all IAM users are associated with relevant groups for proper security and access control.
Troubleshooting Steps:
If an IAM user is not assigned to any group, follow these troubleshooting steps:
- 1.Log in to the AWS Management Console.
- 2.Go to the IAM service.
- 3.Select "Users" from the left navigation menu.
- 4.Identify the user(s) not assigned to any group.
- 5.Verify if the user does not have any other missing or incorrect configuration. This might require checking individual user settings.
- 6.Optionally, check if any IAM groups are missing or not properly defined for the specific NIST 800-53 Revision 4 requirements.
- 7.Use the AWS CLI or SDKs to script the necessary changes if multiple users need to be added to groups simultaneously.
Necessary Codes:
No codes needed for this rule.
Remediation Steps:
To assign an IAM user to a group in compliance with NIST 800-53 Revision 4, follow these steps:
- 1.Log in to the AWS Management Console.
- 2.Go to the IAM service.
- 3.Select "Users" from the left navigation menu.
- 4.Identify the user to whom you want to assign a group.
- 5.Click on the user's name to access the user details page.
- 6.Scroll down to the "Groups" section.
- 7.Click on the "Add user to group" button.
- 8.Select the appropriate group(s) that align with the NIST 800-53 Revision 4 requirements.
- 9.Click "Add to group" to assign the user to the selected group(s).
- 10.Verify the user is now associated with the assigned group(s) in the "Groups" section of the user details page.
Note: Repeat these steps for any additional users who need to be assigned to groups to meet the compliance requirements.
CLI Command for Bulk Assignments:
If multiple IAM users need to be assigned to groups simultaneously, you can use the AWS CLI for efficient bulk assignments. Follow these steps:
- 1.Open the AWS CLI or terminal.
- 2.Use the following command to assign multiple users to a group:
aws iam add-user-to-group --group-name <group-name> --user-names <user1> <user2> <user3> ...
Replace
<group-name><user1> <user2> <user3>- 1.Execute the command to add the selected users to the specified group.
Conclusion:
Assigning IAM users to at least one group is crucial for compliance with NIST 800-53 Revision 4. By following the troubleshooting steps and remediation guide, you can ensure that all IAM users are associated with relevant groups, enhancing security and access control within your AWS account.
