The Duo Source provides a secure endpoint to receive authentication logs from the Duo Authentication Logs API. It securely stores the required authentication, scheduling, and state tracking information.
This Source is available in the Fed deployment.
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 information, log, and resource.
A Duo Source tracks errors, reports its health, and start-up progress. You’re informed, in real-time, if the Source is having trouble connecting, if there's an error requiring user action, or if it is healthy and collecting by utilizing Health Events.
A Duo Source goes through the following states when created:
- Pending. Once the Source is submitted, it is validated, stored, and placed in a Pending state.
- Started. A collection task is created on the Hosted Collector.
- Initialized. The task configuration is complete in Sumo Logic.
- Authenticated. The Source successfully authenticated with Duo.
- Collecting. The Source is actively collecting data from Duo.
If the Source has any issues during any one of these states, it is placed in an Error state.
When you delete the Source, it is placed in a Stopping state. When it has successfully stopped, it is deleted from your Hosted Collector.
On the Collection page, the Health and Status for Sources is displayed. Use Health Events to investigate issues with collection. You can click the text in the Health column, such as Error, to open the issue in Health Events to investigate.
Hover your mouse over the status icon to view a tooltip with details on the detected issue.
Create a Duo Source
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:
In Sumo Logic, select Manage Data > Collection > Collection.
On the Collectors page, click Add Source next to a Hosted Collector.
Enter a Name to display for the Source in the Sumo web application. The description is optional.
(Optional) For Source Category, enter any string to tag the output collected from the Source. Category metadata is stored in a searchable field called
Forward to SIEM. Check the checkbox to forward your data to Cloud SIEM Enterprise. When configured with the Forward to SIEM option the following metadata fields are set:
<eventType>is the value of the field from the JSON event, such as authentication or enrollment.
(Optional) Fields. Click the +Add Field link to define the fields you want to associate, each field needs a name (key) and value.
- A green circle with a check mark is shown when the field exists in the Fields table schema.
- 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
duofederal.com instead of the default
duosecurity.com 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
api-xxxx-duofederal.com if the Duo Federal edition service has been opted in. For more information, refer to the Duo Federal Edition Guide.
Duo Domain. Provide your API hostname, such as
Integration Key. Provide the Duo Integration Key you want to use to authenticate collection requests.
Secret Key. Provide the Duo Secret Key you want to use to authenticate collection requests.
(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.
When you are finished configuring the Source, click Submit.
When Sumo Logic detects an issue it is tracked by Health Events. The following table shows the three possible error types, the reason the error would occur, if the Source attempts to retry, and the name of the event log in the Health Event Index.
|Type||Reason||Retries||Retry Behavior||Health Event Name|
|ThirdPartyConfig||Normally due to an invalid configuration. You'll need to review your Source configuration and make an update.||No retries are attempted until the Source is updated.||Not applicable||ThirdPartyConfigError|
|ThirdPartyGeneric||Normally due to an error communicating with the third party service APIs.||Yes||The Source will retry for up to 90 minutes, after which it quits.||ThirdPartyGenericError|
|FirstPartyGeneric||Normally due to an error communicating with the internal Sumo Logic APIs.||Yes||The Source will retry for up to 90 minutes, after which it quits.||FirstPartyGenericError|
Restarting your Source
If your Source encounters ThirdPartyConfig errors, you can restart it from either the Sumo Logic UI or Sumo Logic API.
To restart your source in the Sumo Logic platform, follow the steps below:
- Open the Collection page, and go to Manage Data > Collection > Collection.
- Select the source and click the information icon on the right side of the row.
- The API usage information popup is displayed. Click the Restart Source button on the bottom left.
- Click Confirm to send the restart request.
- The bottom left of the platform will provide a notification informing you the request was successful.
To restart your source using the Sumo Management API, follow the instructions below:
- Example endpoint:
Sumo Logic endpoints like
api.sumologic.com are different in deployments outside
us1. For example, an API endpoint in Europe would begin
api.eu.sumologic.com. A service endpoint in
us2 (Western U.S.) would begin
service.us2.sumologic.com. For more information, see Sumo Logic Endpoints.
Sources can be configured using UTF-8 encoded JSON files with the Collector Management API. See how to use JSON to configure Sources for details.
|config||JSON Object||Yes||Contains the configuration parameters for the Source.|
|schemaRef||JSON Object||Yes||Use ||not modifiable|
|sourceType||String||Yes||Use ||not modifiable|
The following table shows the config parameters for a Duo Source.
|String||Yes||Type a desired name of the Source. The name must be unique per Collector. This value is assigned to the metadata field ||modifiable|
|String||No||null||Type a description of the Source.||modifiable|
|String||No||null||Type a category of the source. This value is assigned to the metadata field ||modifiable|
|JSON Object||No||JSON map of key-value fields (metadata) to apply to the Collector or Source. Use the boolean field _siemForward to enable forwarding to SIEM.||modifiable|
|String||Yes||Provide your API hostname, such as api-****.duosecurity.com. modifiable|
|String||Yes||Provide the Duo Integration Key you want to use to authenticate collection requests.||modifiable|
|String||Yes||Provide the Duo Secret Key you want to use to authenticate collection requests.||modifiable|
