Enable S3 Bucket Cross-Region Replication Rule
This rule ensures S3 bucket cross-region replication is enabled for data redundancy and disaster recovery.
| Rule | S3 bucket cross-region replication should be enabled |
| Framework | NIST 800-53 Revision 4 |
| Severity | ✔ Critical |
Rule Description:
S3 bucket cross-region replication should be enabled to comply with the NIST 800-53 Revision 4 security standard. Cross-region replication ensures that data stored in an S3 bucket is automatically replicated to another S3 bucket located in a different region. This adds an extra layer of data protection by maintaining multiple copies of the data in different geographical locations.
Troubleshooting Steps:
- 1.Verify if the S3 bucket cross-region replication is already enabled for the bucket in question.
- 2.If replication is not enabled, ensure that the necessary permissions are granted for the replication process.
- 3.Check if the source and destination S3 buckets are in different regions.
- 4.Ensure that the destination bucket is properly configured to receive the replicated data.
Necessary Codes:
There are no specific codes required for this rule since cross-region replication is a configuration setting in the AWS Management Console or can be applied using the AWS Command Line Interface (CLI).
Step-by-step Guide for Remediation:
- 1.Log in to the AWS Management Console.
- 2.Navigate to the S3 service.
- 3.Select the source S3 bucket for which you want to enable cross-region replication.
- 4.Click on the "Management" tab in the bucket properties.
- 5.Under "Replication," click on the "Edit" button.
- 6.Enable cross-region replication by selecting the "Enable" option.
- 7.Choose the destination region for replication.
- 8.Select or create a new destination bucket in the chosen region.
- 9.Configure the replication options as per your requirements, such as encryption and IAM roles.
- 10.Review the configuration and click on the "Save" button to enable cross-region replication.
Note: Ensure that the appropriate IAM roles and permissions are in place for the replication process to function correctly. It is recommended to follow the principle of least privilege when granting these permissions.
By following the above steps, you should be able to enable cross-region replication for an S3 bucket, thereby ensuring compliance with the NIST 800-53 Revision 4 security standard.
