Detect when a Duo bypass code is used to authenticate a user request.


This rule monitors successful authentication events in Cisco Duo logs where the reason is set to bypass_user.

Triage and Response

  1. Contact the user {{}} to confirm they used the bypass code.
  2. If the user is unaware, investigate the authentication event, focusing on the IP address {{@access_device.ip}}, application {{}}, and user {{}} involved.
  3. If the event is deemed malicious, begin your organization’s incident response process to contain the affected account or device.
