Overview

Panther can collect the following Duo logs via the Duo API:

How to onboard Duo logs to Panther

To onboard Duo logs to Panther, follow the steps below. You can also view the data ingestion video overview for a quick walkthrough of Duo log onboarding.

Step 1: Create a Duo application

Follow the instructions here to create a new Duo application.
Note that only administrators with the Owner role can create or modify an Admin API application in the Duo Admin Panel.
Grant the application Grant read log permissions.

Step 2: Create a new Duo source in Panther

In the lefthand navigation bar of your Panther Console, click Configure > Log Sources.
Click Create New.
Select Duo from the list of available log sources. Click Start Setup.
On the next screen, enter a descriptive name for the source (for example, My Duo logs) and select the type of logs you want to monitor.
Click Setup.
Fill in the fields below:
- Integration Key: Enter the integration key of the Duo app.
- Secret Key: Enter the secret key of the Duo app.
- API Hostname: Enter the API hostname of the Duo app.
Click Setup. You will be directed to a success screen:

You can optionally enable one or more Detection Packs.
The Trigger an alert when no events are processed setting defaults to YES. We recommend leaving this enabled, as you will be alerted if data stops flowing from the log source after a certain period of time. The timeframe is configurable, with a default of 24 hours.
