Use ingestion scripts deployed as Cloud Run functions

Supported in:

Google Security Operations has provided a set of ingestion scripts, written in Python, that are intended to be deployed as Cloud Run functions. These scripts enable you to ingest data from the following log sources, listed by name and log type.

  • Armis Google Security Operations Integration
  • Aruba Central (ARUBA_CENTRAL)
  • Azure Event Hub (configurable log type)
  • Box (BOX)
  • Citrix Cloud audit logs (CITRIX_MONITOR)
  • Citrix session metadata (CITRIX_SESSION_METADATA)
  • Cloud Storage (configurable log type)
  • Duo Activity (DUO_ACTIVITY)
  • Duo Admin (DUO_ADMIN)
  • MISP (MISP_IOC)
  • OneLogin (ONELOGIN_SSO)
  • OneLogin user context (ONELOGIN_USER_CONTEXT)
  • Proofpoint (configurable log type)
  • Pub/Sub (configurable log type)
  • Slack audit logs (SLACK_AUDIT)
  • STIX/TAXII threat intelligence (STIX)
  • Tenable.io (TENABLE_IO)
  • Trend Micro Cloud App Security (configurable log type)
  • Trend Micro Vision One audit logs (TREND_MICRO_VISION_AUDIT)

These scripts are located in the Google Security Operations GitHub repository.

Known limitation: When these scripts are used in a stateless environment such as Cloud Run functions, they may not send all logs to Google Security Operations because they lack checkpoint functionality. Google Security Operations has tested the scripts with the Python 3.9 runtime.

Before you begin

Read the following resources that provide context and background information that enable you to use the Google Security Operations ingestion scripts effectively.

Assemble the files for a single log type

Each sub-directory in Google Security Operations GitHub contains files that ingest data for a single Google Security Operations log type. The script connects to a single source device and then sends raw logs to Google Security Operations using the Ingestion API. We recommend that you deploy each log type as a separate Cloud Run function. Access the scripts in the Google Security Operations GitHub repository. Each sub-directory in GitHub contains the following files specific to the log type it ingests.

  • main.py is the ingestion script specific to the log type. It connects to the source device and ingests data to Google Security Operations.
  • .env.yml stores configuration required by the Python script and is specific to the deployment. You modify this file to set configuration parameters required by the ingestion script.
  • README.md provides information about configuration parameters.
  • Requirements.txt defines the dependencies required by the ingestion script. In addition, the common folder contains utility functions that all ingestion scripts depend on.

Perform the following steps to assemble the files that ingest data for a single log type:

  1. Create a deployment directory to store the files for the Cloud Run function. This will contain all files needed for the deployment.
  2. Copy all files from the GitHub sub-directory of the selected log type, for example OneLogin User Context, to this deployment directory.
  3. Copy the common folder and all contents to the deployment directory.

  4. The contents of the directory will look similar to the following:

    one_login_user
├─common
│  ├─__init__.py
│  ├─auth.py
│  ├─env_constants.py
│  ├─ingest.py
│  ├─status.py
│  └─utils.py
├─env.yml
├─main.py
└─requirements.txt

Configure the scripts

  1. Launch a Cloud Shell session.
  2. Connect with SSH to a Google Cloud Linux VM. See Connect to Linux VMs using Google tools.

  3. Upload the ingestion scripts by clicking More > Upload or Download to move your files or folders to or from Cloud Shell.

    Files and folders can only be uploaded to and downloaded from your home directory. For more options to transfer files between Cloud Shell and your local workstation, see [Upload and download files and folders from Cloud Shell](/shell/docs/uploading-and-downloading-files#upload_and_download_files_and_folders.

  4. Edit the .env.yml file for the function and populate the required environment variables. The following table lists runtime environment variables common to all ingestion scripts.

    Variable name Description Required Default Secret
    CHRONICLE_CUSTOMER_ID Google Security Operations customer ID. Yes None No
    CHRONICLE_REGION Google Security Operations region. Yes us
    Other valid values: asia-northeast1, asia-south1, asia-southeast1, australia-southeast1, europe, europe-west2, europe-west3, europe-west6, europe-west9, europe-west12, me-central1, me-central2, me-west1, northamerica-northeast2, and southamerica-east1.    		 No
    CHRONICLE_SERVICE_ACCOUNT Contents of the Google Security Operations service account JSON file. Yes None Yes
    CHRONICLE_NAMESPACE The namespace that the Google Security Operations logs are labeled with. For information about Google Security Operations namespaces, see Work with asset namespaces. No None No

  5. Each script requires environment variables specific to the script. See Configuration parameters by log type for details about the environment variables required by each log type.

Environment variables marked as Secret = Yes must be configured as secrets in Secret Manager. See Secret Manager pricing for information on the cost of using Secret Manager.

See Creating and accessing secrets for detailed instructions.

After the secrets are created in Secret Manager, use the secret resource name as the value for environment variables. For example: projects/{project_id}/secrets/{secret_id}/versions/{version_id}, where {project_id}, {secret_id}, and {version_id} are specific to your environment.

Set up a scheduler or trigger

All scripts, except Pub/Sub, are implemented to collect the data at periodic intervals from a source device. You must set up a trigger using Cloud Scheduler to fetch data over time. The ingestion script for Pub/Sub continuously monitors the Pub/Sub subscription. For more information, see Running services on a schedule and Using Pub/Sub to trigger a Cloud Run function.

Deploy the Cloud Run function

  1. Launch a Cloud Shell session.
  2. Connect via SSH to a Google Cloud Linux VM. See Connect to Linux VMs using Google tools.
  3. Change to the directory where you copied ingestion scripts.

  4. Execute the following command to deploy the Cloud Run function.

    gcloud functions deploy <FUNCTION NAME> --service-account <SERVICE_ACCOUNT_EMAIL> --entry-point main --trigger-http --runtime python39 --env-vars-file .env.yml

    Replace <FUNCTION_NAME> with the name you define for the Cloud Run function.

    Replace <SERVICE_ACCOUNT_EMAIL> with the email address of the service account you want your Cloud Run function to use. account you want your Cloud Run function to use.

    If you don't change directory to the location of the files, make sure to use the --source option to specify the location of the deployment scripts.

    The service account running your Cloud Run function must have the Cloud Functions Invoker (roles/cloudfunctions.invoker) and Secret Manager Secret Accessor (roles/secretmanager.secretAccessor) roles.

View runtime logs

The ingestion scripts print runtime messages to stdout. Cloud Run functions provides a mechanism to view log messages. For more information, see the Cloud Functions information about Viewing runtime logs.

Configuration parameters by log type

Armis Google Security Operations Integration

Following is the flow of the script:

  1. Verify environment variables.

  2. Deploy the script to Cloud Run functions.

  3. Collect data using the ingestion script.

  4. Ingest collected data into Google Security Operations.

  5. Parse collected data through corresponding parsers in Google Security Operations.
