Description
Detects when a principal (user or service account) is exempted from GCP data access audit logging. This is a critical security event as it reduces visibility into privileged operations and may indicate an attempt to hide malicious activity. Adversaries may exempt their accounts from audit logging to evade detection while performing reconnaissance, privilege escalation, or data exfiltration. This rule monitors SetIamPolicy operations that add audit log exemptions for ADMIN_READ, DATA_READ, or DATA_WRITE log types.
