Chronicle RBAC API

The Chronicle APIs enable customers to programmatically access their security data directly through API calls to the Chronicle platform that stores and processes the data. This is the same security data presented in the Chronicle UI through your Chronicle 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 Chronicle.

How to authenticate with the Chronicle API

This Chronicle 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 Chronicle 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.oauth2 import service_account
from googleapiclient import _auth

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 Chronicle API
# Scope.
credentials = service_account.Credentials.from_service_account_file(SERVICE_ACCOUNT_FILE, scopes=SCOPES)

# Build an HTTP client to make authorized OAuth requests.
http_client = _auth.authorized_http(credentials)

# <your code continues here>

Examples (in Python) for making OAuth authenticated requests to the Chronicle API are provided for each API call referenced in this document.
