Duo Security

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

To use this application with InsightIDR:

  • Enable the Duo Admin API
  • Configure the event source in InsightIDR

Enable Duo Admin API

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

To configure the Duo Admin API 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. Note: In Duo, the API Hostname relates to the Subdomain in InsightIDR, and the Secret Key relates to Token/Secret in InsightIDR.
  5. Go to the Properties page.
  6. Enable the following permissions:
    • Grant read information
    • Grant read log
    • Grant read resource
  7. Click Save Changes.

  10. Create a new credential:
    • Click Create New.
    • Specify a name for the credential.
    • Enter the Subdomain in the form of api-xxxxxxxx. The Subdomain is the first part of the API hostname in the Duo Admin API. For example, if you had api-12ab3456.yourdomain.com enter api-12ab3456 in the Subdomain field.
    • Enter the Token/Secret. The Token/Secret is the Secret Key in the Duo Admin API.
