CloudTrail Trail Log File Validation Rule
This rule ensures CloudTrail trail log file validation is enabled to enhance system and information integrity.
| Rule | CloudTrail trail log file validation should be enabled |
| Framework | NIST 800-53 Revision 4 |
| Severity | ✔ Critical |
Rule Description
This rule requires enabling CloudTrail log file validation for compliance with NIST 800-53 Revision 4. Log file validation helps ensure the integrity of CloudTrail log files, indicating whether they have been tampered with or modified since their creation. By enabling log file validation, organizations comply with the security controls outlined in NIST 800-53 Revision 4.
Troubleshooting Steps (if applicable)
There are no specific troubleshooting steps for enabling CloudTrail log file validation. However, if you encounter issues during the process, consider the following general troubleshooting steps:
- 1.Ensure that you have sufficient permissions to enable CloudTrail log file validation.
- 2.Confirm that your CloudTrail trails are properly configured and activated.
- 3.Check if any conflicting settings or policies are preventing the enabling of log file validation.
- 4.Consult the official AWS documentation or the AWS Support team for further assistance, if needed.
Required Code (if applicable)
There is no specific code required to enable CloudTrail log file validation. Configuration is done through the AWS Management Console or AWS Command Line Interface (CLI).
Remediation Steps
To enable CloudTrail log file validation for compliance with NIST 800-53 Revision 4, follow these steps:
AWS Management Console:
- 1.Open the AWS Management Console and navigate to the CloudTrail service.
- 2.Select the desired trail that needs log file validation enabled.
- 3.Click on the "Edit" button for the selected trail.
- 4.In the "Advanced" section or tab, locate the "Log file integrity validation" option.
- 5.Toggle the switch or checkbox to enable log file integrity validation.
- 6.Click on the "Save" or "Update" button to apply the changes.
AWS Command Line Interface (CLI):
- 1.Open a terminal or command prompt and ensure you have the AWS CLI installed and configured with appropriate credentials.
- 2.Run the following command to enable log file validation for the selected trail:
aws cloudtrail update-trail --name <trail_name> --enable-log-file-validation
Replace
<trail_name>- 1.Verify that log file validation has been enabled by rechecking the trail's settings. Use the following command to describe the trail and check the status:
aws cloudtrail describe-trails --trail-name-list <trail_name>
Conclusion
By following the aforementioned steps, you will successfully enable CloudTrail log file validation for compliance with NIST 800-53 Revision 4. This ensures the integrity of your CloudTrail log files and helps meet the security controls recommended by NIST.
