Rule: EC2 Instances Should Have IAM Profile Attached

Rule Description

Troubleshooting Steps

2. 1.

   Check IAM Policies: Verify if the necessary IAM policies for FFIEC compliance have been defined. These policies should include the appropriate permissions, restrictions, and access controls required by FFIEC.

4. 2.

   Validate IAM Role: Ensure that the IAM role required for FFIEC compliance exists. If not, create a new IAM role with the necessary policies attached.

6. 3.

   Review Instance IAM Associations: Check the IAM profiles associated with the instances to identify if any EC2 instances are lacking the required IAM profile.

8. 4.

   Update IAM Associations: For instances without the FFIEC IAM profile, update their IAM associations by attaching the relevant IAM profile.

10. 5.

    Verify Permissions: After attaching the IAM profile, verify that the assigned permissions align with FFIEC compliance. Review the policies attached to the IAM role to confirm the desired access controls are in place.

Necessary Codes

import boto3

# Specify the EC2 instance ID and IAM profile name for FFIEC compliance
instance_id = 'your_instance_id'
iam_profile_name = 'ffiec_iam_profile'

# Create an EC2 resource object
ec2_resource = boto3.resource('ec2')

# Retrieve the instance object
instance = ec2_resource.Instance(instance_id)

# Attach the IAM profile to the instance
response = instance.modify_attribute(
    IamInstanceProfile={
        'Name': iam_profile_name
    }
)

# Check the response status
if response['ResponseMetadata']['HTTPStatusCode'] == 200:
    print(f"IAM profile '{iam_profile_name}' attached to instance '{instance_id}' successfully.")
else:
    print("Failed to attach the IAM profile to instance.")

Remediation Steps

2. 1.

   Log in to the AWS Management Console.

4. 2.

   Go to the EC2 service.

6. 3.

   Select the appropriate region.

8. 4.

   Navigate to the "Instances" section.

10. 5.

    Locate the EC2 instance that lacks the FFIEC IAM profile.

12. 6.

    Right-click on the instance and select "Instance Settings."

14. 7.

    From the dropdown options, click on "Attach/Replace IAM role."

16. 8.

    In the "IAM role" section, select the FFIEC IAM profile from the list.

18. 9.

    Click on the "Apply" button to attach the IAM profile to the instance.

20. 10.

    Verify that the IAM profile has been successfully attached by reviewing the instance details or using the AWS CLI command described below.

CLI Command for Verification

aws ec2 describe-instances --instance-ids <instance_id> --query 'Reservations[].Instances[].IamInstanceProfile'

<instance_id>
