Note

This feature is at the Preview stage.

Data Security Posture Management scans buckets for sensitive information in storage. You can create bucket scans and manage scan results in Object Storage via the management console.

Getting startedGetting started

Make sure the service account you will use to scan a bucket and work with scan results has the following roles:

  • dspm.editor or higher: Required to create scans.
  • dspm.admin or dspm.viewer or higher: Required to view scan results with masked or public data, respectively.
  • dspm.viewer or higher: Required to download scan results.
  • dspm.viewer or higher: Required to export results. Also the service account that will perform the export must have write permissions for the target bucket.

Creating a scanCreating a scan

Tip

The Object Storage UI allows you to scan individual buckets for sensitive data. To monitor data in multiple buckets at the folder, cloud, or organization level, use the DSPM module inside Yandex Security Deck.

Management console
  1. In the management console, select a folder.

  2. Navigate to Object Storage.

  3. Click the name of the bucket you want to create a scan for.

  4. Go to the Security → Sensitive data search tab.

  5. Click New scan.

    Note

    If access to the bucket is controlled by a policy, allow access to Security Deck IP addresses in the bucket policy settings. For a list of addresses, see Public IP address ranges.

  6. Under Sensitive data search, select the data categories to scan for. You can select all the available categories at once or any combination of them.

  7. Optionally, under Include files into the scope, specify the object keys or prefixes to include in the scan. By default, the scan targets all supported file formats.

    Note

    Currently, you cannot scan objects encrypted with a KMS key.

  8. Click Create scan.

The scan will start automatically. To repeat the scan, click Repeat scan.

Viewing scan resultsViewing scan results

Management console

  2. Navigate to Object Storage.

  3. Click the name of the bucket in question.

  4. Go to the Security → Sensitive data search tab.

  5. Sensitive data found during the scan, if any, will be displayed on the Results tab. The information about each detected object is presented in the following columns:

    • Data type: Search category of the data, e.g., FULL-NAME-RU-ML: Full name.
    • Found occurrence: Sensitive data found.
    • Object: Path to the file the data was found in.

Downloading scan resultsDownloading scan results

As you download, a CSV file with the scan results is saved locally on your computer.

Note

The file can contain a maximum of 10,000 sensitive data records. To export a larger number of records, use export to Object Storage.

Management console
  1. In the management console, select a folder.
  2. Navigate to Object Storage.
  3. Click the name of the bucket in question.
  4. Navigate to the Security → Sensitive data search tab.
  5. Click More → Download results.
  6. In the window that opens, specify how to display names, contact information, and other personal data, then click Download file.

Exporting scan resultsExporting scan results

When exporting, the file with scan results is saved to the bucket you select.

Management console
  1. In the management console, select a folder.

  2. Navigate to Object Storage.

  3. Click the name of the bucket in question.

  4. Navigate to the Security → Sensitive data search tab.

  5. Click More → Export to bucket.

  6. In the window that opens, set the export settings:

    • In the Bucket field, select the bucket to save the results to.
    • In the Path to bucket field, set the prefix of the object to save the results to.
    • In the File name field, specify the name of the file to save the results to. The file will automatically get the .csv extension.
    • In the Service account field, select the service account with the storage.uploader role for the selected bucket and kms.keys.encrypter for the encryption key, if the bucket is encrypted.
    • Under Display sensitive data, specify how to display names, contact information, and other personal data.
    • Click Export to export the parameter check results.

Viewing scan errorsViewing scan errors

  1. In the management console, select a folder.
  2. Navigate to Object Storage.
  3. Click the name of the bucket in question.
  4. Navigate to Security → Sensitive data search → Messages and errors.

For more information about scanning errors, see Troubleshooting Data Security Posture Management (DSPM).

An object key is the full name of a file within a bucket, often formatted as a filesystem path. Here are some examples of keys: docs/reports/2026/april.pdf, photos/trips/paris/img001.jpg.

A prefix is the initial part of a key displayed in the UI as a folder. Here are some examples of prefixes: photos/, photos/trips/, photos/trips/paris/.
