Creating a DSPM data source

A data source contains information about the Yandex Object Storage buckets to scan as well as additional settings.

Before you start using DSPM, set up the default folder to store Security Deck data.

To create a data source:

Security Deck UI
  1. Go to Yandex Security Deck.

  2. In the left-hand panel, select Data Security Posture Management and go to the Data sources tab.

  3. In the top-right corner, click Create source.

  4. Add the resources you want to scan to the data source:

    • To add individual buckets, click Select bucket and select one or more buckets from one or more of your available folders.

      If required, use filters by access settings (Limited or Public) and by bucket name.

    • To add clouds or folders to your data source, click Select cloud or folder and select all or some of the clouds and/or folders available to you.

      All buckets in the selected clouds and/or folders will be added to the data source. In this case, DSPM will scan both the buckets that already exist in these clouds and folders and any other buckets added to them by the time the scan is run.

  5. Under Include in selection, specify one or more scan scopes:

    • All files: To scan all files saved in the buckets.

    • DOC/TXT: To scan .doc, .docx, and .txt text files.

    • XLS/CSV: To scan .xls, .xlsx, and .csv spreadsheet files.

    • PPT: To scan .ppt and .pptx presentation files.

    • PDF: To scan .pdf document files.

    • HTML/XML: To scan .html and .xml files.

    • Images: To scan .jpg, .jpeg, .png, .gif, .webp, and .svg image files.

    • Custom filter: To scan all files whose names do or do not match the specified patterns:

      • File name contains: To scan files whose names match the specified pattern.
      • File name does not contain: To ignore files whose names match the specified pattern.

      Specify the patterns using the RE2 regular expression syntax. You can specify patterns in both fields, in which case the scan will use the AND logic to select files.

    You can select multiple filters at the same time; the system will use the OR logic to apply them.

  6. If you want to add resources with different scan scope selection parameters to the same data source, click Add resource group and repeat steps 4 and 5 in the section that appears.

    You can add any number of resource groups to a single data source for scanning.

  7. Under Information about source, indicate the data source name you will use to select this source when creating a scan. Follow these naming requirements:

    • It must be from 2 to 63 characters long.
    • It can only contain lowercase Latin letters, numbers, and hyphens.
    • It must start with a letter and cannot end with a hyphen.

    Click on the right side of the Name field to automatically generate a name for the data source you are creating.

  8. Click Create source.

As a result, the new source will appear in the list of data sources. Now you can select this data source when creating a scan.
