Google Security Operations RBAC API
The Google Security Operations APIs enable customers to programmatically access their security data directly through API calls to the Google Security Operations platform that stores and processes the data. This is the same security data presented in the Google Security Operations UI through your Google Security Operations customer account.
This capability enables you to develop new applications or modify existing applications to retrieve and process all your security data currently stored in Google Security Operations.
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/
Examples (in Python) for making OAuth authenticated requests to the Google Security Operations API are provided for each API call referenced in this document.
