Creating and managing Notification Configs

This page describes how to use the Security Command Center API notifications feature, including the following examples:

  • Create a NotificationConfig
  • Get a NotificationConfig
  • Update a NotificationConfig
  • Delete a NotificationConfig
  • List NotificationConfig
  • Receive Pub/Sub notifications

Before you begin

To use the examples on this page, you need to complete the guide to Set up finding notifications.

To execute the following examples, you need an Identity and Access Management (IAM) role with appropriate permissions:

  • Get and List NotificationConfig: Security Center Notification Viewer or Editor
  • Update and Delete NotificationConfig: Security Center Notification Editor

Learn more about Security Command Center roles.

Creating a NotificationConfig

To create a NotificationConfig, you must have:

  • An existing Pub/Sub topic that you want to send notifications to.
  • Required IAM roles for your service account or the account you're using to run gcloud tool commands.

For more information, see the step to Set up a Pub/Sub topic in the guide to Set up finding notifications.

Before you create a NotificationConfig, note the following:

  • Each organization can have a limited number of NotificationConfig files. For more information, see Quotas and limits.
  • You must have the Organization Administrator IAM role so that you can grant appropriate roles to the notifications service account or gcloud tool account.

The NotificationConfig includes a filter field that limits notifications to useful events. This field accepts all of the filters that are available in the Security Command Center API findings.list method.

To grant the account the Security Center Notifications Configurations Editor IAM role using the gcloud command-line tool:

  1. Set environment variables:

    1. Set your organization name:

        export ORGANIZATION_ID=organization-id

    2. Set the email of the service account that you created when you set up finding notifications or the account you're using to run gcloud tool commands:

      • Set the email of the account used to run gcloud tool commands:

        export EMAIL=your-username@email.com

      • Or set the email of the service account:

        export EMAIL=service-account-name@$CONSUMER_PROJECT.iam.gserviceaccount.com

  2. Grant the necessary role to the service account or the account you used with gcloud tool commands:

    • Grant the role to the account used to run gcloud tool commands:

         gcloud organizations add-iam-policy-binding \
     $ORGANIZATION_ID \
     --member="user:$EMAIL" \
     --role='roles/securitycenter.notificationConfigEditor'

    • Or grant the role to the service account:

         gcloud organizations add-iam-policy-binding \
     $ORGANIZATION_ID \
     --member="serviceAccount:$EMAIL" \
     --role='roles/securitycenter.notificationConfigEditor'

After you grant the service account or gcloud tool account permissions, create the NotificationConfig using the language or platform of your choice:

gcloud

  # The numeric ID of the organization
  ORGANIZATION_ID=organization-id

  # The topic to which the notifications are published
  PUBSUB_TOPIC="projects/project-id/topics/topic-id"

  # The description for the NotificationConfig
  DESCRIPTION="Notifies for active findings"

  # Filters for active findings
  FILTER="state=\"ACTIVE\""

  gcloud scc notifications create notification-name \
    --organization "$ORGANIZATION_ID" \
    --description "$DESCRIPTION" \
    --pubsub-topic $PUBSUB_TOPIC \
    --filter "$FILTER"

Notifications are now published to the Pub/Sub topic you specified. To publish notifications, Security Command Center uses an organization-level service account in the form of service-org-organization-id@gcp-sa-scc-notification.iam.gserviceaccount.com with the role securitycenter.notificationServiceAgent. This organization-level service account role is required for notifications to function.

Getting a NotificationConfig

To get a NotificationConfig, you must have an IAM role that includes the securitycenter.notification.get permission.

Updating a NotificationConfig

To update a NotificationConfig, you must have an IAM role that includes the securitycenter.notification.update permission.

When you update using a field mask, only the fields you specify are updated. If you don't use a field mask, all mutable fields in the NotificationConfig are replaced by the new values. You can use a field mask to update the Pub/Sub topic and description.

To complete this example, you must be subscribed to the new topic, and your notifications service account must have the pubsub.topics.setIamPolicy permission on the topic. To grant an appropriate role:

  1. Set environment variables:

    1. Set the topic ID:

        export TOPIC_ID=topic-id

    2. Set the project ID for the project in which you enabled the notifications API:

        export CONSUMER_PROJECT=project-id

    3. Set the email of the service account that you created in the previous steps:

        export SERVICE_ACCOUNT_EMAIL=service-account-name@$CONSUMER_PROJECT.iam.gserviceaccount.com

  2. Grant the notifications service account a role with the pubsub.topics.setIamPolicy permission:

       gcloud pubsub topics add-iam-policy-binding \
     projects/$CONSUMER_PROJECT/topics/$TOPIC_ID \
     --member="serviceAccount:$SERVICE_ACCOUNT_EMAIL" \
     --role='roles/pubsub.admin'

After you grant the service account role, update the NotificationConfig description, Pub/Sub topic and filter using the language of your choice:

gcloud

  # The topic to which the notifications are published
  PUBSUB_TOPIC="projects/project-id/topics/topic-id"

  # The description for the NotificationConfig
  DESCRIPTION="description"
  # The numeric ID of the organization and the name of the notification that you want to update
  NOTIFICATION="organizations/organization-id/notificationConfigs/notification-name"

  gcloud scc notifications update $NOTIFICATION
    --description "$DESCRIPTION" \
    --pubsub-topic $PUBSUB_TOPIC \
    --filter       $FILTER

Deleting a NotificationConfig

To delete a NotificationConfig, you must have an IAM role that includes the securitycenter.notification.delete permission.

When you delete a NotificationConfig, the securitycenter.notificationServiceAgent role stays on the Pub/Sub topic. If you aren't using the Pub/Sub topic in any other NotificationConfig, remove the role from the topic. For more information, see access control.

Delete a NotificationConfig using the language of your choice:

gcloud

  # The numeric ID of the organization and the name of the notification that you want to delete
  NOTIFICATION="organizations/organization-id/notificationConfigs/notification-name"

  gcloud scc notifications delete $NOTIFICATION

Python

from google.cloud import securitycenter as securitycenter

Listing NotificationConfigs

To list NotificationConfigs, you must have an IAM role that includes the securitycenter.notification.list permission.

All Security Command Center API lists are paginated. Each response returns a page of results and a token to return the next page. The default pageSize is 10. You can configure page size to a minimum of 1, and a maximum of 1000.

List NotificationConfigs using the language of your choice:

gcloud

  # The numeric ID of the organization
  ORGANIZATION=organization-id

  gcloud scc notifications list $ORGANIZATION

Python

from google.cloud import securitycenter as securitycenter

client = securitycenter.SecurityCenterClient()

Receiving Pub/Sub notifications

This section provides a sample notification message and examples that show how to convert a Pub/Sub message into a NotificationMessage that contains a finding.

Notifications are published to Pub/Sub in the JSON format. Following is an example of a notification message:

{
   "notificationConfigName": "organizations/organization-id/notificationConfigs/config-id",
   "finding": {
     "name": "organizations/organization-id/sources/source-id/findings/finding-id",
     "parent": "organizations/organization-id/sources/source-id",
     "state": "ACTIVE",
     "category": "TEST-CATEGORY",
     "securityMarks": {
       "name": "organizations/organization-id/sources/source-id/findings/finding-id/securityMarks"
     },
     "eventTime": "2019-07-26T07:32:37Z",
     "createTime": "2019-07-29T18:45:27.243Z"
   }
 }

Convert a Pub/Sub message into a NotificationMessage using the language of your choice:

gcloud

The gcloud tool doesn't support converting a Pub/Sub message into a NotificationMessage. You can use the gcloud tool to get a NotificationMessage and print the JSON directly in your terminal:

  # The subscription used to receive published messages from a topic
  PUBSUB_SUBSCRIPTION="projects/project-id/subscriptions/subscription-id"

  gcloud pubsub subscriptions pull $PUBSUB_SUBSCRIPTION

Python

# Requires https://cloud.google.com/pubsub/docs/quickstart-client-libraries#pubsub-client-libraries-python
import concurrent

from google.cloud import pubsub_v1
from google.cloud.securitycenter_v1 import NotificationMessage

# TODO: project_id = "your-project-id"
# TODO: subscription_name = "your-subscription-name"

def callback(message):
    print("Received message")

    notification_msg = NotificationMessage.from_json(message.data)

    print(
        "Notification config name: {}".format(
            notification_msg.notification_config_name
        )
    )
    print("Finding: {}".format(notification_msg.finding))

    # Ack the message to prevent it from being pulled again
    message.ack()

subscriber = pubsub_v1.SubscriberClient()
subscription_path = subscriber.subscription_path(project_id, subscription_name)

streaming_pull_future = subscriber.subscribe(subscription_path, callback=callback)

print("Listening for messages on {}...\n".format(subscription_path))
try:
    streaming_pull_future.result(timeout=1)  # Block for 1 second
except concurrent.futures.TimeoutError:
    streaming_pull_future.cancel()
