This rule ensures that there is at least one enabled CloudTrail trail present in a specific region.
| Rule | At least one enabled trail should be present in a region |
| Framework | FedRAMP Low Revision 4 |
| Severity | ✔ Low |
Rule Description:
According to the FedRAMP Low Revision 4 requirement, there should be at least one enabled trail present in a specific region. This rule ensures that logging and monitoring are properly configured to track activities and events within the region, helping to enhance the security posture and compliance of the system.
Troubleshooting Steps:
If there are issues with meeting this requirement, the following troubleshooting steps can be taken:
- 1.
Verify the presence of trails: Check if there are any trails enabled within the specified region. Trails can be monitored using the AWS Management Console, AWS CLI, or SDKs.
- 2.
Identify disabled trails: If no trails are enabled, review the list of trails in the region and identify any that might be disabled.
- 3.
Check trail status: Verify the status of the disabled trails. If any trail is not enabled, it needs to be reconfigured to meet the compliance requirement.
- 4.
Review cloud service provider documentation: Consult the documentation provided by the cloud service provider to understand how to enable trails or troubleshoot issues with existing trails.
- 5.
Consider technical limitations: In some cases, certain AWS services or configurations might have limitations that prevent the use of trails in specific regions. Investigate if any such limitation exists and explore alternative logging and monitoring mechanisms if required.
Necessary Codes:
No specific codes are required for this rule. However, the AWS Command Line Interface (CLI) commands can be used to manage and configure trails if necessary.
Step-by-Step Guide for Remediation:
Follow these steps to ensure compliance with the FedRAMP Low Revision 4 requirement:
- 1.
Identify the region: Determine the specific region for which the requirement needs to be met.
- 2.
Check existing trails: Use the AWS Management Console or AWS CLI to review the enabled and disabled trails in the specified region.
- 3.
Enable a trail: If no enabled trail exists, create a new trail using the AWS Management Console or by running the following CLI command:
aws cloudtrail create-trail --name trail-name --s3-bucket-name bucket-name --is-multi-region-trail --region region-nameEnsure that you replace
,trail-name
, andbucket-name
with appropriate values.region-name - 4.
Enable CloudTrail logging: If an existing trail is disabled, enable it using the AWS Management Console or by running the following CLI command:
aws cloudtrail start-logging --name trail-name --region region-nameReplace
andtrail-name
with the appropriate values.region-name - 5.
Test the trail: Verify that the trail is active and functioning as expected by generating some activity in the region and reviewing the logs.
- 6.
Periodically review and monitor trails: Regularly check the status of trails to ensure continued compliance. Consider implementing automated monitoring and alerting mechanisms for trails to promptly detect and address any issues.
By following these steps, you can ensure that at least one enabled trail is present in the specified region, meeting the requirement of FedRAMP Low Revision 4.
