GCP Audit Logs - Detect Organization Policy Deletion or Updation

Description

'Detects when a Google Cloud Platform organization policy is deleted or updated. Organization policies provide centralized control over your organization's cloud resources and help ensure security and compliance. Deletion or modification of org policies may indicate an attempt to bypass security controls or weaken the security posture of GCP projects. Adversaries may delete or update organization policies to disable security constraints before performing malicious activities.'
