This rule mandates the presence of at least one multi-region AWS CloudTrail in an account.
| Rule | At least one multi-region AWS CloudTrail should be present in an account |
| Framework | NIST 800-53 Revision 5 |
| Severity | ✔ Medium |
Rule Description
At least one multi-region AWS CloudTrail should be present in an account to comply with the NIST 800-53 Revision 5 security control.
Troubleshooting Steps
If you encounter any issues or errors while setting up the multi-region AWS CloudTrail, you can follow these troubleshooting steps:
- 1.Verify CloudTrail configuration: Double-check the CloudTrail settings to ensure you have correctly configured a multi-region trail.
- 2.Check IAM permissions: Make sure the IAM user or role associated with the CloudTrail has the necessary permissions to create and manage the trail across regions.
- 3.Verify AWS regions: Ensure that the regions you selected for the multi-region CloudTrail are supported by AWS CloudTrail.
- 4.Review CloudTrail logs: Examine the CloudTrail logs to identify any specific error messages or events that might indicate the cause of the issue.
- 5.Review CloudTrail documentation: Refer to the official AWS CloudTrail documentation for additional troubleshooting guidance and FAQs.
Necessary Code
To set up a CloudTrail in multiple regions, you can use the AWS Command Line Interface (CLI) or AWS Management Console. Here's an example code snippet using the AWS CLI:
aws cloudtrail create-trail --name MyMultiRegionTrail --is-multi-region --s3-bucket-name my-cloudtrail-bucket --region us-west-2 --tags Key=Name,Value=MyMultiRegionTrail
Step-by-Step Guide for Remediation
To ensure compliance with the NIST 800-53 Revision 5 security control, follow these step-by-step instructions to set up a multi-region CloudTrail using the AWS Management Console:
- 1.Sign in to the AWS Management Console: Go to the AWS Management Console (https://console.aws.amazon.com/) and provide your credentials.
- 2.Navigate to the CloudTrail service: Locate the "Services" dropdown in the upper-left corner of the console, search for "CloudTrail," and click on it.
- 3.Click on "Trails" in the left sidebar: Select the "Trails" option from the left sidebar menu.
- 4.Click on "Create trail": On the "Trails" page, click on the "Create trail" button.
- 5.Enter trail details: Provide a name for the trail in the "Trail name" field and ensure the "Apply trail to all regions" option is selected.
- 6.Configure storage settings: Choose the appropriate settings for storing the CloudTrail logs. You can select an existing S3 bucket or create a new one.
- 7.Configure trail events: Specify the AWS services and specific events you want to trace in your CloudTrail logs.
- 8.Enable log file validation: Optionally, enable log file validation to ensure the integrity of your CloudTrail logs.
- 9.Select CloudWatch Logs (optional): If you want to send CloudTrail logs to CloudWatch Logs, enable this option and select an existing CloudWatch Logs group or create a new one.
- 10.Specify advanced settings (optional): Optionally, you can configure advanced settings such as KMS encryption, tags, and logging for S3 buckets that contain CloudTrail logs.
- 11.Review the trail settings: Double-check all the settings you have configured for the trail.
- 12.Click on "Create trail": Once you are satisfied with the settings, click on the "Create trail" button to create the multi-region CloudTrail.
- 13.Verify the trail creation: After creating the trail, verify that it appears in the list of trails in the CloudTrail console. Ensure that the trail has the desired multi-region configuration.
By following these steps, you can successfully set up a multi-region AWS CloudTrail to meet the requirements of NIST 800-53 Revision 5 in your AWS account.
