Rule: S3 Bucket Cross-Region Replication Enabled
Ensure S3 bucket cross-region replication is enabled to improve data redundancy and resilience.
| Rule | S3 bucket cross-region replication should be enabled |
| Framework | Federal Financial Institutions Examination Council (FFIEC) |
| Severity | ✔ Critical |
Rule Description
S3 bucket cross-region replication should be enabled for Federal Financial Institutions Examination Council (FFIEC) to ensure data redundancy and availability in case of an outage or disaster in the primary region.
Troubleshooting Steps
- 1.Check if cross-region replication is already enabled for the S3 bucket.
- 2.Verify if the FFIEC compliance regulations require cross-region replication for data protection.
- 3.Ensure that the necessary IAM permissions are granted for S3 bucket replication.
Necessary Codes
There are no specific codes required for this rule. However, you can use the AWS Command Line Interface (CLI) to check the bucket's cross-region replication configuration and modify it if necessary.
Remediation Steps
- 1.Open the AWS Management Console and navigate to the Amazon S3 service.
- 2.Click on the target S3 bucket that needs cross-region replication enabled for FFIEC compliance.
- 3.Select the "Management" tab and click on "Replication".
- 4.If there is no existing replication configuration, click on "Add rule" to create one.
- 5.Choose a source bucket (the current bucket) and click "Next".
- 6.Select the destination region where you want to replicate the data and click "Next".
- 7.Configure additional replication options if needed (e.g., storage class, encryption) and click "Next".
- 8.Review the replication rule summary and click "Save" to enable cross-region replication.
- 9.Test the replication by uploading a test object to the source bucket and verifying its presence in the destination bucket.
Note: Ensure that you have the necessary IAM permissions to enable and configure cross-region replication for S3 buckets.
Conclusion
Enabling cross-region replication for the S3 bucket associated with FFIEC compliance ensures data redundancy and availability. By following the provided steps, you can enable cross-region replication and comply with the required regulations.
