Duo Security

Duo Security is a multi-factor authentication provider that you can use to authenticate to the platform, as well as track user ingress and admin activity.

To use this application with InsightIDR:

Configure Duo AdminAPI

InsightIDR provides support for monitoring user accounts and authentications within Duo Security. This functionality is available by configuring a secret key with Duo Security which provides out of-network access to its data.

The AdminAPI is not enabled by default. Contact your Duo representative to enable this feature. You can read the AdminAPI documentation here: https://duo.com/docs/adminapi.

To configure the Duo AdminAPI to work with InsightIDR:

  1. Log in to the Duo Admin Panel and go to Applications.
  2. On the lefthand menu, select Applications > Protect an Application.
  3. Search for "Admin API."
  4. Copy the integration key, secret key, and API hostname for later configuration in InsightIDR.
  5. Go to the Properties page.
  6. Enable the following permissions:
    • Grant read information
    • Grant read log
    • Grant read resource
  7. Click the Save Changes button.
