Logging metric filter and alert for project ownership assignments/changes should be configured¶
Admin activity and data access access logs produced by audit logs enable security analysis, resource change tracking, and compliance auditing. Configuring the metric filter and alerts for audit configuration changes helps prevent unwanted, accidental, or malicious modifications that may make it difficult or impossible to conduct investigations or perform audits.
Google Cloud Console¶
This is a two-part process. First, you create the log metric. Next, you create an alert policy.
Step 1: Make sure the log metric is present:
Navigate to Log-based Metrics and click CREATE METRIC.
Ensure Metric Type is set to Counter.
Under Details, enter a name and description, and set Units to 1.
Under Filter selection, clear any text in the Build filter box and enter the following:
protoPayload.methodName="SetIamPolicy" AND protoPayload.serviceData.policyDelta.auditConfigDeltas:*
Click Create Metric.
Step 2: To create the alert policy:
Navigate to Logs-based Metrics and identify the newly created metric under the section User-defined Metrics.
Click the 3-dot icon in the rightmost column for the new metric and select Create alert from Metric.
Set Aggregator to Count and set the desired time period.
Under Configuration, choose the alerting threshold and configuration that makes sense for your organization. For example, a threshold of zero (0) for the most recent value ensures that a notification is triggered for every owner change in the project:
Set `Configuration`: - Condition: above - Threshold: 0 - For: most recent value
Configure the desired notifications channels in the section Notifications.
Name the policy and click Save.
