Audit and alert on security group changes in Workspace

Track and notify on sensitive group membership changes using a delegated service account, with reliable detection of real-world update events.

The problem

Sensitive groups (like admin or finance) must not change membership without oversight, but Workspace does not emit native alerts for these events. Manual review is slow and misses timing; automation must catch every addition or removal, even if changes are rapid or revert quickly.

How it works

  1. Maintain a baseline snapshot of monitored security groups and their members.
  2. Regularly poll group membership using the Admin SDK as a delegated service account.
  3. Compare each poll to the previous state to detect additions and removals.
  4. Send targeted alerts (email, webhook, etc.) when a change is detected, including the actor and timestamp if available.
  5. Store a durable log of detected changes for audit.

What changes

Every membership change is captured and surfaced promptly, with a clear audit trail for investigation and compliance.

The trap in this one. Group membership changes in the Admin SDK can take several minutes to propagate, especially for large groups or when multiple changes are made in rapid succession. If you poll too frequently, you may read an incomplete or inconsistent state, resulting in false-positive or missed alerts. Always account for propagation lag and corroborate with subsequent polls before sending critical alerts.

Questions people ask

Can the Admin SDK provide real-time notifications?

No. There is no webhook or push mechanism for group membership changes; polling is required, and you must handle eventual consistency.

How do I attribute a group change to a specific user?

The group membership list does not include actor information. To capture who made the change, correlate with Admin audit logs via the Reports API.
