Forwarder Management API

You can use the Google Security Operations Forwarder Management API to do the following programmatically:

  • Create and manage forwarders.
  • Create and manage collectors.
  • Get the file contents for a Google Security Operations forwarder's configuration.(.conf) and authentication (_auth.conf) files.

Forwarders are composed of one or more collectors. Each collector's configuration specifies its ingestion mechanism (for example, File, Kafka, PCAP, Splunk, or Syslog) and log type.

Assuming hardware requirements are met, you can use many collectors on the same forwarder to ingest data from a variety of mechanisms and log types. For example, you can install a forwarder with two syslog collectors listening for PAN_FIREWALL and CISCO_ASA_FIREWALL data on separate ports, respectively.

The API lets you create forwarders and their collectors in your Google Security Operations instance. Once a forwarder is created, you can use the Generate Forwarder Files endpoint to get the file contents (as JSON payload) for a forwarder's configuration (.conf) and authentication (_auth.conf) files. These contents can then be written to their respective .conf files for deployment with the Google Security Operations Forwarder service on a Windows or Linux system.

For Python samples that use the Forwarder Management API, see the GitHub repository.

Create a forwarder and its collector(s)

A forwarder must be created before any of its collectors can be created.

To create a forwarder and its collector(s):

  1. Create a forwarder.
  2. Create a collector for the forwarder.
  3. (Optional) Repeat Step 2 to add more collectors.

How to authenticate with the Google Security Operations API

This Google Security Operations API uses the OAuth 2.0 protocol for authentication and authorization. Your application can complete these tasks using either of the following implementations:

  • Using the Google API Client Library for your computer language.

  • Directly interfacing with the OAuth 2.0 system using HTTP.

See the reference documentation for the Google Authentication library in Python.

Google Authentication libraries are a subset of the Google API client libraries. See other language implementations.

Getting API authentication credentials

Your Google Security Operations representative will provide you with a Google Developer Service Account Credential to enable the API client to communicate with the API.

You also must provide the Auth Scope when initializing your API client. OAuth 2.0 uses a scope to limit an application's access to an account. When an application requests a scope, the access token issued to the application is limited to the scope granted.

Use the following scope to initialize your Google API client:

https://www.googleapis.com/auth/chronicle-backstory

Python example

The following Python example demonstrates how to use the OAuth2 credentials and HTTP client using google.oauth2 and googleapiclient.

# Imports required for the sample - Google Auth and API Client Library Imports.
# Get these packages from https://pypi.org/project/google-api-python-client/ or run $ pip
# install google-api-python-client from your terminal
from google.auth.transport import requests
from google.oauth2 import service_account

SCOPES = ['https://www.googleapis.com/auth/chronicle-backstory']

# The apikeys-demo.json file contains the customer's OAuth 2 credentials.
# SERVICE_ACCOUNT_FILE is the full path to the apikeys-demo.json file
# ToDo: Replace this with the full path to your OAuth2 credentials
SERVICE_ACCOUNT_FILE = '/customer-keys/apikeys-demo.json'

# Create a credential using Google Developer Service Account Credential and Google Security Operations API
# Scope.
credentials = service_account.Credentials.from_service_account_file(SERVICE_ACCOUNT_FILE, scopes=SCOPES)

# Build a requests Session Object to make authorized OAuth requests.
http_session = requests.AuthorizedSession(credentials)

# Your endpoint GET|POST|PATCH|etc. code will vary below

# Reference List example (for US region)
url = 'https://backstory.googleapis.com/v2/lists/COLDRIVER_SHA256'

# You might need another regional endpoint for your API call; see
# https://cloud.google.com/chronicle/docs/reference/ingestion-api#regional_endpoints

# requests GET example
response = http_session.request("GET", url)

# POST example uses json
body = {
  "foo": "bar"
}
response = http_session.request("POST", url, json=body)

# PATCH example uses params and json
params = {
  "foo": "bar"
}
response = http_session.request("PATCH", url, params=params, json=body)

# For more complete examples, see:
# https://github.com/chronicle/api-samples-python/

Chronicle API query limits

The Chronicle API enforces limits on the volume of requests that can be made by any one customer against the Google Security Operations platform. If you reach or exceed the query limit, the Chronicle API server returns HTTP 429 (RESOURCE_EXHAUSTED) to the caller. When developing applications for the Chronicle API, Google recommends that you enforce rate limits within your system to avoid resource exhaustion. These limits apply to all of the Chronicle APIs, including the Search, Forwarder Management, and Tooling APIs.

The following limit for the Chronicle Forwarder Management API is being enforced and is measured in queries per second (QPS):

Chronicle API API Endpoint Limit
Forwarder Management Create Forwarder 1 QPS
Get Forwarder 1 QPS
List Forwarders 1 QPS
Update Forwarder 1 QPS
Delete Forwarder 1 QPS
Collector Management Create Collector 1 QPS
Get Collector 1 QPS
List Collectors 1 QPS
