Rule: At Least One Enabled Trail Present in a Region
This rule ensures at least one enabled trail exists in a specific region.
| Rule | At least one enabled trail should be present in a region |
| Framework | Federal Financial Institutions Examination Council (FFIEC) |
| Severity | ✔ Low |
Rule Description:
According to the policy set by the Federal Financial Institutions Examination Council (FFIEC), it is required to have at least one enabled trail present in each region. A trail captures and logs important events and activities from various services within the region.
Troubleshooting Steps:
If there is no enabled trail present in a region, it could be due to the following reasons:
- 1.
No trails created: Ensure that trails have been created for the specific region where the rule is being enforced. If no trails are available, you will need to create them.
- 2.
Trails not enabled: Check if the created trails have been enabled. Trails need to be enabled to capture and log events. If trails are not enabled, you will need to enable them.
- 3.
Incorrect region: Verify that the trails are configured in the correct region where the FFIEC policy is being enforced. If the trails are created in a different region, you will need to create new trails in the correct region.
- 4.
Misconfiguration: Review the trail configuration settings to ensure they are correctly set up. Check if any required event types or data sources are missing from the trail configuration.
Necessary Codes:
If using AWS CloudTrail service, the following code can be used to create and enable a trail:
aws cloudtrail create-trail --name my-trail --s3-bucket-name my-bucket --region region-name aws cloudtrail start-logging --name my-trail
Replace 'my-trail' with the desired trail name, 'my-bucket' with the appropriate S3 bucket name, and 'region-name' with the designated region where the policy is enforced.
Remediation Steps:
Follow these step-by-step instructions to remediate the issue:
- 1.
Log in to the AWS Management Console or access the AWS command-line interface (CLI) using appropriate credentials.
- 2.
Choose the appropriate region where the FFIEC policy needs to be enforced.
- 3.
Create a trail if no trails are available. Use the AWS CloudTrail service or equivalent service provided by your cloud provider.
- 4.
Configure the trail settings, ensuring all necessary event types and data sources are included for logging.
- 5.
Enable the trail if it is not already enabled. Use the appropriate CLI command or enable it through the console interface.
- 6.
Test the trail by generating a test event or performing an action that should be captured by the trail.
- 7.
Monitor the trail logs to ensure events are being captured correctly.
- 8.
Repeat the above steps for each region that requires compliance with the FFIEC policy.
By following these steps, you will ensure that at least one enabled trail is present in each region, meeting the requirements set by the FFIEC.
