S3 Bucket Versioning Enabled Rule
This rule ensures S3 bucket versioning is enabled to protect data integrity and prevent accidental deletions.
| Rule | S3 bucket versioning should be enabled |
| Framework | NIST Cybersecurity Framework (CSF) v1.1 |
| Severity | ✔ High |
Rule Description
Enabling versioning for Amazon S3 buckets is a recommended security measure to implement in accordance with the NIST Cybersecurity Framework (CSF) v1. Bucket versioning allows you to preserve multiple versions of an object in an S3 bucket, providing a historical record of changes and the ability to restore previous versions if needed. This enhances data integrity, resilience, and recoverability in case of accidental deletions, data corruption, or security breaches.
Troubleshooting Steps
If versioning is not already enabled for an S3 bucket, you may encounter issues when attempting to enable it. Here are some troubleshooting steps to resolve common problems:
- 1.
Check IAM Permissions: Ensure that your AWS Identity and Access Management (IAM) user or role has the necessary permissions to enable versioning on the bucket. You should have the
permission for the specific bucket.s3:PutBucketVersioning - 2.
Verify Bucket Ownership: Make sure you are the owner of the S3 bucket or have appropriate permissions to modify it. If you are not the owner, contact the bucket owner or an administrator with the necessary privileges to enable versioning.
- 3.
Check Bucket Name and Region: Ensure that you have entered the correct bucket name and the corresponding AWS region when attempting to enable versioning. Mistakenly specifying an incorrect bucket name or region can lead to errors.
- 4.
Review Bucket Limitations: Verify that your bucket does not have any limitations or restrictions that might prevent versioning from being enabled. For example, buckets that are part of Amazon S3 Glacier storage classes do not support versioning.
Necessary Codes (if applicable)
If you are using the AWS Command Line Interface (CLI) to enable versioning for an S3 bucket, you can use the following command:
aws s3api put-bucket-versioning --bucket <bucket-name> --versioning-configuration Status=Enabled

To enable versioning for an S3 bucket in accordance with the NIST Cybersecurity Framework (CSF) v1, follow these steps:
- 1.
Step 1: Access the AWS Management Console: Log in to your AWS account and access the AWS Management Console at https://console.aws.amazon.com.
- 2.
Step 2: Navigate to Amazon S3: Click on the "Services" dropdown in the top navigation bar and select "S3" from the list of available services. This will take you to the Amazon S3 dashboard.
- 3.
Step 3: Select the S3 Bucket: Locate and click on the name of the S3 bucket for which you want to enable versioning.
- 4.
Step 4: Access Bucket Properties: In the bucket overview page, click on the "Properties" tab to view the properties related to the selected bucket.
- 5.
Step 5: Enable Versioning: Scroll down to the "Versioning" section and click on the "Edit" button.
- 6.
Step 6: Enable Versioning for the Bucket: In the "Edit Bucket Versioning" dialog, select the "Enable" option for bucket versioning and click on the "Save" button to apply the changes.
- 7.
Step 7: Verify Versioning Configuration: Once versioning is enabled, you can confirm the status by checking the "Properties" tab of the bucket. The versioning status should now show as "Enabled."
Congratulations! You have successfully enabled versioning for your S3 bucket in accordance with the NIST Cybersecurity Framework (CSF) v1. This will help enhance the security and resilience of your data stored in the bucket.
