Event Information

  • The google.spanner.admin.instance.v1.InstanceAdmin.DeleteInstance event in GCP for CloudSpanner indicates that an instance deletion operation has been initiated.
  • This event signifies that a request has been made to delete a CloudSpanner instance in the specified project and location.
  • The event provides information about the instance being deleted, such as its name, project ID, and location, allowing administrators to track and monitor instance deletion activities in their CloudSpanner environment.

​
Examples

  • Unauthorized deletion of instances: If security is impacted with google.spanner.admin.instance.v1.InstanceAdmin.DeleteInstance in GCP for CloudSpanner, it could potentially allow unauthorized users or malicious actors to delete instances. This could result in the loss of critical data and disrupt business operations.

  • Data exposure: If security is impacted with google.spanner.admin.instance.v1.InstanceAdmin.DeleteInstance, it could lead to the exposure of sensitive data. For example, if an instance is deleted without proper access controls in place, it may expose confidential information to unauthorized individuals.

  • Service disruption: Deleting instances without proper authorization or safeguards can lead to service disruption. This can impact the availability and reliability of applications and services that rely on the CloudSpanner database. It is crucial to ensure that only authorized personnel have the necessary permissions to perform instance deletion operations.

    • Scroll down to the “Audit Logging” section and click on “Enable Audit Logging”.
    • Select the desired audit logs to be enabled (e.g., Admin Activity, Data Access, System Event logs).
    • Save the changes.

Note: These steps may vary slightly depending on the specific version of the GCP Console and CloudSpanner. It is always recommended to refer to the official GCP documentation for the most up-to-date instructions.

​
Using CLI

To remediate the issues mentioned in the previous response for GCP CloudSpanner using GCP CLI, you can follow these steps:

  1. Enable VPC Service Controls for CloudSpanner:

    • Use the following command to enable VPC Service Controls for CloudSpanner: 
      gcloud services vpc-peerings update --service=servicenetworking.googleapis.com --network=projects/[PROJECT_ID]/global/networks/[NETWORK_NAME] --ranges=[IP_RANGE]
    • Replace [PROJECT_ID] with your GCP project ID, [NETWORK_NAME] with the name of your VPC network, and [IP_RANGE] with the IP range of your VPC network.

  2. Implement IAM Roles and Permissions:

    • Use the following command to grant the necessary IAM roles to the appropriate users or service accounts: 
      gcloud projects add-iam-policy-binding [PROJECT_ID] --member=[MEMBER] --role=[ROLE]
    • Replace [PROJECT_ID] with your GCP project ID, [MEMBER] with the email address or service account of the user, and [ROLE] with the desired IAM role.

  3. Enable Audit Logging for CloudSpanner:

    • Use the following command to enable audit logging for CloudSpanner: 
      gcloud logging sinks create [SINK_NAME] storage.googleapis.com/[BUCKET_NAME] --log-filter="resource.type=spanner_instance"
    • Replace [SINK_NAME] with a name for your logging sink, and [BUCKET_NAME] with the name of the Cloud Storage bucket where you want to store the logs.

Please note that the above commands are examples and may need to be modified based on your specific environment and requirements. Make sure to refer to the official GCP documentation for detailed instructions and the latest CLI commands.

​
Using Python

To remediate issues in GCP CloudSpanner using Python, you can follow these steps:

  1. Monitoring and Alerting:

    • Use the Cloud Monitoring API to create custom metrics and alerts for monitoring CloudSpanner instances.
    • Write a Python script to periodically check the metrics and trigger alerts if any thresholds are breached.
    • Here’s an example script to create a custom metric and an alert policy using the Cloud Monitoring API:
    from google.cloud import monitoring_v3

client = monitoring_v3.MetricServiceClient()

# Create a custom metric descriptor
project_name = "projects/my-project"
metric_descriptor = {
    "type": "custom.googleapis.com/my_custom_metric",
    "metric_kind": monitoring_v3.MetricDescriptor.MetricKind.GAUGE,
    "value_type": monitoring_v3.MetricDescriptor.ValueType.DOUBLE,
    "description": "My custom metric",
    "display_name": "My Custom Metric",
}
client.create_metric_descriptor(name=project_name, metric_descriptor=metric_descriptor)

# Create an alert policy
alert_policy = {
    "display_name": "My Alert Policy",
    "combiner": monitoring_v3.AlertPolicy.ConditionCombinerType.AND,
    "conditions": [
        {
            "condition_threshold": {
                "filter": 'metric.type="custom.googleapis.com/my_custom_metric"',
                "comparison": monitoring_v3.ComparisonType.COMPARISON_GT,
                "threshold_value": 100.0,
                "duration": {"seconds": 60},
            },
        },
    ],
    "notification_channels": ["projects/my-project/notificationChannels/my-channel"],
}
client.create_alert_policy(name=project_name, alert_policy=alert_policy)

  2. Backup and Disaster Recovery:

    • Use the Cloud Spanner Backup API to create automated backups of your CloudSpanner databases.
    • Write a Python script to schedule and manage the backup process.
    • Here’s an example script to create a backup:
    from google.cloud import spanner_admin_database_v1

client = spanner_admin_database_v1.DatabaseAdminClient()

# Create a backup
backup_name = "projects/my-project/instances/my-instance/backups/my-backup"
database_name = "projects/my-project/instances/my-instance/databases/my-database"
backup = spanner_admin_database_v1.Backup(
    database=database_name,
    expire_time=spanner_admin_database_v1.timestamp.Timestamp(),
)
client.create_backup(parent="projects/my-project/instances/my-instance", backup_id="my-backup", backup=backup)

  3. Access Control and Permissions:

    • Use the Cloud Identity and Access Management (IAM) API to manage access control and permissions for CloudSpanner resources.
    • Write a Python script to grant or revoke permissions for users or service accounts.
    • Here’s an example script to grant a user the “Cloud Spanner Admin” role:
    from google.cloud import iam

client = iam.IAMClient()

# Grant a user the "Cloud Spanner Admin" role
member = "user:[email protected]"
role = "roles/spanner.admin"
policy = client.get_policy(resource="projects/my-project/instances/my-instance")
policy.bindings.add(role=role, members=[member])
client.set_policy(resource="projects/my-project/instances/my-instance", policy=policy)

Please note that the above scripts are just examples and may need to be modified based on your specific requirements and environment.
