Goal

Detect when a GitHub secret scanning setting has been disabled.

Strategy

This rule monitors GitHub audit logs for when a secret scanning setting has been disabled. GitHub scans repositories for known types of secrets to prevent fraudulent use of secrets that were committed accidentally. 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.
