Creating and managing Notification Configs

Stay organized with collections Save and categorize content based on your preferences.

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

Alternatively, Security Command Center Premium customers can set up Continuous Exports for Pub/Sub in the Security Command Center dashboard.

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:

  • Create NotificationConfig: Security Center Notification Configurations Editor (roles/securitycenter.notificationConfigEditor)
  • Get and List NotificationConfig: Security Center Notification Configurations Viewer (roles/securitycenter.notificationConfigViewer) or Security Center Notification Configurations Editor (roles/securitycenter.notificationConfigEditor)
  • Update and Delete NotificationConfig: Security Center Notification Configurations Editor (roles/securitycenter.notificationConfigEditor)

To grant appropriate roles to a principal that accesses a notificationConfig, you must have one of the following IAM roles:

  • Organization Administrator (roles/resourcemanager.organizationAdmin)
  • Folder IAM Admin (roles/resourcemanager.folderIamAdmin)
  • Project IAM Admin (roles/resourcemanager.projectIamAdmin)

The IAM roles for Security Command Center can be granted at the organization, folder, or project level. Your ability to view, edit, create, or update findings, assets, and security sources depends on the level for which you are granted access. To learn more about Security Command Center roles, see Access control.

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 the principal that creates the notificationConfig.

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 that each organization can have a limited number of NotificationConfig files. For more information, see Quotas and limits.

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.

When you create a NotificationConfig, you specify a parent for the NotificationConfig from the Google Cloud resource hierarchy, either an organization, a folder, or a project. If you need to retrieve, update, or delete the NotificationConfig later, you need to include the numerical ID of the parent organization, folder, or project when you reference it.

To create the NotificationConfig using the language or platform of your choice:

gcloud

# The numeric ID of the parent organization, folder, or project of
# the NotificationConfig.
# The value that you specify here must match the command flag that you use
# in the gcloud scc notifications create command, either --organizations,
# --folder, or --project.
ORGANIZATION_ID=ORGANIZATION_ID
# FOLDER_ID=FOLDER_ID
# PROJECT_ID=PROJECT_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\""

# The following command specifies an organization as the parent of the NotificationConfig
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, a service account is created for you in the form of service-org-ORGANIZATION_ID@gcp-sa-scc-notification.iam.gserviceaccount.com. This service account is created when you create your first NotificationConfig and is automatically granted the securitycenter.notificationServiceAgent role on the IAM policy for PUBSUB_TOPIC when creating the notification config. This 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.

After you grant the necessary permissions, 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 type and ID of the parent organization, folder, or project
  # and the name of the notification that you want to update
  NOTIFICATION="PARENT_TYPE/PARENT_ID/notificationConfigs/NOTIFICATION_NAME"

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

Replace the following:

  • PROJECT_ID with your project ID.
  • TOPIC_ID with your topic ID.
  • DESCRIPTION with your notification description.
  • PARENT_TYPE with organizations, folders, or projects, depending on which level of the resource hierarchy was specified in the notification configuration.
  • PARENT_ID with the numeric ID of the parent resource.
  • NOTIFICATION_NAME with the name of the NotificationConfig.

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 type and ID of the parent organization, folder, or project
  # and the name of the notification that you want to update
NOTIFICATION="PARENT_TYPE/PARENT_ID/notificationConfigs/NOTIFICATION_NAME"

gcloud scc notifications delete $NOTIFICATION

Replace the following:

  • PARENT_TYPE with organizations, folders, or projects, depending on which level of the resource hierarchy was specified in the notification configuration.
  • PARENT_ID with the numeric ID of the parent resource.
  • NOTIFICATION_NAME with the name of the NotificationConfig.

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 parent organization, folder, or project for
  # which to list the notifications. 
  ORGANIZATION_ID=ORGANIZATION_ID
  # FOLDER_ID=FOLDER_ID
  # PROJECT_ID=PROJECT_ID

  gcloud scc notifications list $ORGANIZATION_ID

Replace ORGANIZATION_ID, FOLDER_ID, or PROJECT_ID with the numeric ID of the organization, folder, or project for which to list the notifications.

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 CLI doesn't support converting a Pub/Sub message into a NotificationMessage. You can use the gcloud CLI 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

Replace the following:

  • PROJECT_ID with your project ID.
  • SUBSCRIPTION_ID with your subscription ID.

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 the data received for debugging purpose if needed
    print(f"Received message: {message.data}")

    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
