Rule: S3 Bucket Cross-Region Replication Enabled
This rule ensures S3 bucket cross-region replication is enabled for enhanced data redundancy and disaster recovery.
| Rule | S3 bucket cross-region replication should be enabled |
| Framework | FedRAMP Low Revision 4 |
| Severity | ✔ Critical |
Rule Description:
According to FedRAMP Low Revision 4 guidelines, S3 bucket cross-region replication should be enabled. This rule ensures that data stored in S3 buckets is replicated across different AWS regions for disaster recovery and business continuity purposes.
Troubleshooting Steps:
If cross-region replication is not enabled for an S3 bucket, you may follow these steps to troubleshoot the issue:
- 1.
Verify the S3 bucket configuration: Ensure that the bucket for which cross-region replication needs to be enabled exists and can be accessed.
- 2.
Check IAM permissions: Ensure that the AWS Identity and Access Management (IAM) user or role executing the configuration has sufficient permissions to enable cross-region replication for an S3 bucket.
- 3.
Check S3 bucket replication configuration: Verify the bucket's replication configuration options, including source and destination regions, replication rules, and filters.
- 4.
Review IAM roles and policies: Ensure that the IAM role or policy associated with the bucket has permissions to replicate objects across regions.
- 5.
Validate network connectivity: Check if there are any network connectivity issues between the source and destination regions that may prevent cross-region replication.
Necessary Codes:
The following is an example code snippet for enabling cross-region replication for an S3 bucket using the AWS Command Line Interface (CLI):
aws s3api put-bucket-replication --bucket source-bucket --replication-configuration file://replication-configuration.json

source-bucketStep-by-Step Guide for Remediation:
To enable cross-region replication for an S3 bucket, you can follow these step-by-step instructions:
- 1.
Log in to the AWS Management Console.
- 2.
Navigate to the S3 service.
- 3.
Select the S3 bucket for which you want to enable cross-region replication.
- 4.
Click on the "Management" tab.
- 5.
Select "Replication" from the left-hand menu.
- 6.
Click on the "Add rule" button.
- 7.
In the "Source" section, choose the source region from where you want to replicate objects.
- 8.
In the "Destination" section, choose the destination region where you want to replicate objects.
- 9.
Configure the replication rules based on your requirements. You can choose to replicate all objects or specify filters to replicate only certain objects.
- 10.
Optionally, enable replication time control to specify the time frame for replication.
- 11.
Review the configuration and click on the "Save" button to enable cross-region replication for the S3 bucket.
- 12.
Verify that the replication configuration has been applied successfully.
By following these steps, you will enable cross-region replication for an S3 bucket and ensure compliance with FedRAMP Low Revision 4 guidelines.
