Goal

Detect when GitHub OIDC/SAML single sign-on (SSO) has been modified.

Strategy

This rule monitors GitHub audit logs for when OIDC/SAML SSO has been modified. GitHub allows for use of a SSO solution to increase security and centralize identity and access for the web application that your team uses. Disabling these settings could lead to a degradation in the organization’s security posture.

Triage and response

  1. Determine if the change taken by {{@github.actor}} is authorized.
  2. If the change was not authorized or was unexpected, begin your organization’s incident response process and investigate.
