# AWS S3 buckets should be versioned

> Checks that AWS S3 bucket versioning is enabled.

Checks that AWS S3 bucket versioning is enabled.

## About

When you connect Amazon Web Services (AWS) to DSALTA, the platform retrieves the list of resources in your environment using read-only API access. DSALTA then checks whether this configuration is in place. If it is not, DSALTA activates this check so you can remediate it.

## Why This Matters

Without versioning, a single overwrite or deletion is permanent. Keeping prior versions protects against accidental loss and tampering and supports recovery requirements in SOC 2 and ISO 27001.

## How to Fix

**Before you begin**

* Ensure you have **Admin** access to the AWS account.

**Enable S3 bucket versioning**

1. Sign in to the [AWS Console](https://console.aws.amazon.com/) and navigate to **S3 → Buckets**.
2. Select the bucket and open the **Properties** tab.
3. Under **Bucket Versioning**, click **Edit**, choose **Enable**, and save.
4. (Optional) Add a lifecycle rule to expire or transition old versions.

Once versioning is enabled, DSALTA retrieves the change on the next sync and sets the check status to **Passing**.

## Frequently Asked Questions

  <Accordion title="What happens if it keeps failing?">
    A failing check appears in your **Data Library → Tests** dashboard. Work through the steps above; once the underlying configuration is fixed, the status updates automatically on the next sync.
  </Accordion>

  <Accordion title="Can I exclude this check?">
    Yes. If it does not apply to your environment, mark it as **Not Applicable** with a justification. The exclusion is documented for auditors.
  </Accordion>

  <Accordion title="Does DSALTA change my Amazon Web Services (AWS) configuration?">
