Vendor configuration

You need to create an Admin API app and copy the integration key, secret key, and domain to provide to Sumo Logic when creating your Duo Source. Grant the Admin API permission to read informationlog, and resource.

Source configuration

When you create a Duo Source, you add it to a Hosted Collector. Before creating the Source, identify the Hosted Collector you want to use or create a new Hosted Collector. For instructions, see Configure a Hosted Collector.

To configure a Duo Source:

  1. In the main Sumo Logic menu, select Manage Data > Collection > Collection.  
  2. On the Collectors page, click Add Source next to a Hosted Collector.
  3. Search for and select Duo.
  4. Enter a Name to display for the Source in the Sumo web application. The description is optional.
  5. (Optional) For Source Category, enter any string to tag the output collected from the Source. Category metadata is stored in a searchable field called _sourceCategory.
  6. Forward to SIEM. Check the checkbox to forward your data to Cloud SIEM.
  7. (Optional) Fields. Click the +Add Field link to define the fields you want to associate, each field needs a name (key) and value.
    • green check circle.png A green circle with a check mark is shown when the field exists in the Fields table schema.
    • orange exclamation point.png An orange triangle with an exclamation point is shown when the field doesn't exist in the Fields table schema. In this case, an option to automatically add the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema it is ignored, known as dropped.

    If you are using the Duo Federal edition service when connecting APIs, it's recommended to use instead of the default domain. Our Duo C2C lets you allow to configure the API domain as it contains the specific customer ID information. For example, you can use or if the Duo Federal edition service has been opted in. For more information, refer to the Duo Federal Edition Guide.

  8. Duo Domain. Provide your API hostname, such as api-********
  9. Integration Key. Provide the Duo Integration Key you want to use to authenticate collection requests.
  10. Secret Key. Provide the Duo Secret Key you want to use to authenticate collection requests. 
  11. (Optional) The Polling Interval is set for 300 seconds by default, you can adjust it based on your needs. This sets how often the Source checks for new data.
  12. When you are finished configuring the Source, click Submit.
