Rule: Ensure Presence of Multi-Region AWS CloudTrail

Rule Description:

Remediation:

Step 1: Create a new multi-region CloudTrail trail:

2. 1.
   Open the AWS Management Console.
4. 2.
   Navigate to the CloudTrail service.
6. 3.
   Click on "Trails" in the left-hand navigation menu.
8. 4.
   Click on the "Create trail" button.
10. 5.
    Enter a trail name that indicates its multi-region nature (e.g., "FFIEC-MultiRegion-CloudTrail").
12. 6.
    Select the desired storage location for CloudTrail logs (e.g., an S3 bucket).
14. 7.
    Enable logging for all AWS regions by selecting the "All" option under "Apply trail to all regions."
16. 8.
    Configure other CloudTrail settings as per your requirements, such as log file encryption, CloudWatch Logs integration, etc.
18. 9.
    Click on "Create trail" to create the multi-region CloudTrail.

Step 2: Configure CloudTrail for all regions:

2. 1.
   In the CloudTrail console, locate the newly created trail.
4. 2.
   Click on the trail name to open its configuration settings.
6. 3.
   Click on the "Event selectors" tab.
8. 4.
   Under "Data events," click on the "Edit" button.
10. 5.
    Enable logging of data events for all supported services by selecting the "All" option.
12. 6.
    Click on "Save" to apply the changes.

Step 3: Validate the implementation:

2. 1.
   Verify that the multi-region CloudTrail trail is active and collecting logs for all regions.
4. 2.
   Manually generate some API activity in different regions of your AWS account.
6. 3.
   Verify that the CloudTrail logs capture the generated API activity for all regions.
8. 4.
   Perform regular checks to ensure the CloudTrail service is functioning correctly and logging activities across all regions.

Troubleshooting:

2. 1.
   Verify IAM permissions: Ensure that the IAM role or user associated with CloudTrail has the necessary permissions to create and manage resources, access S3 buckets, and write logs to CloudWatch Logs if enabled.
4. 2.
   Check S3 bucket permissions: Ensure that the S3 bucket configured for CloudTrail logging has the appropriate permissions to receive and store logs. Cross-check the bucket and object-level permissions for any misconfigurations.
6. 3.
   Review CloudTrail settings: Double-check the trail configuration to ensure that you have enabled logging for all AWS regions and enabled data events for relevant services.
8. 4.
   Check CloudTrail service health: Monitor the health status of the CloudTrail service within the AWS Management Console or via the AWS CLI to identify any ongoing service disruptions.
10. 5.
    Troubleshoot CloudTrail delivery failures: In case CloudTrail logs are not being delivered to the designated S3 bucket, review CloudTrail delivery logs and examine potential issues with S3 bucket policies, IAM roles, or other associated components.
