Scc Owner Not Monitored Log Metric Alert

What the Solution Is

Creating a logs-based counter metric coupled with a Cloud Monitoring alert policy establishes continuous, real-time detection for changes made to administrative permissions. It specifically tracks modifications to project-level ownership roles recorded in Cloud Audit Logs.

How It Meets the Requirements

• Continuous IAM monitoring: The solution captures SetIamPolicy calls handled by cloudresourcemanager.googleapis.com. By filtering for protoPayload.serviceData.policyDelta.bindingDeltas.role="roles/owner" where the action is ADD or REMOVE (as well as ProjectOwnership or projectOwnerInvitee), any grant or revocation of ownership immediately increments the metric.
• Resolves OWNER_NOT_MONITORED finding: Security Command Center's Security Health Analytics detector checks that the project contains a LogsMetric resource with this exact Cloud Resource Manager filter and verifies that an associated alertPolicy exists with active conditions and notificationChannels.
• Real-time alerting: When the metric increments above the threshold (typically > 0 within the evaluation period), Cloud Monitoring triggers notifications to defined security channels such as PagerDuty, email, or Pub/Sub.

Key Advantages and Capabilities

• Automated compliance validation: Directly satisfies CIS GCP Benchmark control 2.4 and resolves corresponding SCC posture findings.
• Near real-time response: Fires alerts within moments of unauthorized privilege escalation.
• Granular policy filtering: Isolates sensitive role deltas without generating excessive noise from non-privileged IAM modifications.
• Native integrations: Connects directly with organizational incident response workflows via Cloud Monitoring notification channels.

Why This Is Optimal

This architecture leverages built-in Google Cloud Observability and Security Command Center mechanisms. It requires no third-party software, eliminates batch polling delays, and natively satisfies CIS compliance auditing algorithms.
