IAM User Should Not Have Any Inline or Attached Policies Rule
This rule specifies that IAM users should not have any inline or attached policies for cybersecurity control.
| Rule | IAM user should not have any inline or attached policies |
| Framework | Federal Financial Institutions Examination Council (FFIEC) |
| Severity | ✔ Low |
Rule Description:
IAM users should not have any inline or attached policies for the Federal Financial Institutions Examination Council (FFIEC).
Inline and attached policies can grant access permissions to various AWS resources and services. However, in the context of the Federal Financial Institutions Examination Council (FFIEC), it is essential to ensure that IAM users do not possess any policies related to FFIEC. This rule helps enforce compliance with security and regulatory requirements specific to FFIEC.
Remediation Steps:
- 1.
Identify IAM Users:
- Identify all IAM users in your AWS account who may have inline or attached policies.
- 2.
Review Policies:
- Review the policies attached to each IAM user to determine if there are any policies related to FFIEC.
- To list the policies attached to an IAM user, you can use the AWS Command Line Interface (CLI) with the following command:
aws iam list-attached-user-policies --user-name <IAM-username>
- 3.
Review Inline Policies:
- Check if there are any inline policies directly attached to the IAM user.
- To view the inline policies for an IAM user, you can use the AWS CLI with the following command:
aws iam list-user-policies --user-name <IAM-username>
- 4.
Remove FFIEC Policies:
For any identified policies related to FFIEC, you should remove them.
To detach a policy from an IAM user, execute the following AWS CLI command:
aws iam detach-user-policy --user-name <IAM-username> --policy-arn <policy-arn>If there are inline policies, remove them by executing the following AWS CLI command:
aws iam delete-user-policy --user-name <IAM-username> --policy-name <policy-name>
- 5.
Monitoring and Compliance:
- Regularly monitor IAM users to ensure they do not have any new or reattached policies related to FFIEC.
- Utilize AWS CloudTrail to track policy changes and identify any non-compliant actions.
- Configure CloudWatch Events and Lambda functions to automate the monitoring process and send alerts if any non-compliance is detected.
Troubleshooting:
If you encounter any issues while remediating this rule, consider the following troubleshooting steps:
- 1.
Permission Errors:
- Ensure that the IAM user performing the remediation steps has the necessary permissions to modify IAM policies.
- Allocate the required IAM policies, such as "iam:DetachUserPolicy" and "iam:DeleteUserPolicy," to the user if they lack the necessary permissions.
- 2.
Policy Not Found:
- Double-check the policy name or ARN when using the
oraws iam detach-user-policy
commands.aws iam delete-user-policy - Ensure that you accurately specify the correct IAM user as well.
If the troubleshooting steps do not resolve the issue, consider reviewing the AWS IAM documentation or contacting AWS Support for further assistance.
Note: Ensure that you comply with any additional regulations or policies applicable to your organization apart from FFIEC.
