SentinelOne (using Azure Functions) connector for Microsoft Sentinel

The SentinelOne data connector provides the capability to ingest common SentinelOne server objects such as Threats, Agents, Applications, Activities, Policies, Groups, and more events into Microsoft Sentinel through the REST API. Refer to API documentation: https://<SOneInstanceDomain>.sentinelone.net/api-doc/overview for more information. The connector provides ability to get events which helps to examine potential security risks, analyze your team's use of collaboration, diagnose configuration problems and more.

Prerequisites

To integrate with SentinelOne (using Azure Functions) make sure you have:

  • Microsoft.Web/sites permissions: Read and write permissions to Azure Functions to create a Function App is required. See the documentation to learn more about Azure Functions.
  • REST API Credentials/permissions: SentinelOneAPIToken is required. See the documentation to learn more about API on the https://<SOneInstanceDomain>.sentinelone.net/api-doc/overview.

Vendor installation instructions

Note

This connector uses Azure Functions to connect to the SentinelOne API to pull its logs into Microsoft Sentinel. This might result in additional data ingestion costs. Check the Azure Functions pricing page for details.

(Optional Step) Securely store workspace and API authorization key(s) or token(s) in Azure Key Vault. Azure Key Vault provides a secure mechanism to store and retrieve key values. Follow these instructions to use Azure Key Vault with an Azure Function App.

Note

This data connector depends on a parser based on a Kusto Function to work as expected which is deployed as part of the solution. To view the function code in Log Analytics, open Log Analytics/Microsoft Sentinel Logs blade, click Functions and search for the alias SentinelOne and load the function code or click here. The function usually takes 10-15 minutes to activate after solution installation/update.

STEP 1 - Configuration steps for the SentinelOne API

Follow the instructions to obtain the credentials.

  1. Log in to the SentinelOne Management Console with Admin user credentials.
  2. In the Management Console, click Settings.
  3. In the SETTINGS view, click USERS
  4. Click New User.
  5. Enter the information for the new console user.
  6. In Role, select Admin.
  7. Click SAVE
  8. Save credentials of the new user for using in the data connector.

NOTE :- Admin access can be delegated using custom roles. Please review SentinelOne documentation to learn more about custom RBAC.

STEP 2 - Choose ONE from the following two deployment options to deploy the connector and the associated Azure Function

IMPORTANT: Before deploying the SentinelOne data connector, have the Workspace ID and Workspace Primary Key (can be copied from the following).

Option 1 - Azure Resource Manager (ARM) Template

Use this method for automated deployment of the SentinelOne Audit data connector using an ARM Template.

  1. Click the Deploy to Azure button below.

    Deploy To Azure Deploy to Azure Gov

  2. Select the preferred Subscription, Resource Group and Location.

NOTE: Within the same resource group, you can't mix Windows and Linux apps in the same region. Select existing resource group without Windows apps in it or create new resource group. 3. Enter the SentinelOneAPIToken, SentinelOneUrl (https://<SOneInstanceDomain>.sentinelone.net) and deploy. 4. Mark the checkbox labeled I agree to the terms and conditions stated above. 5. Click Purchase to deploy.

Option 2 - Manual Deployment of Azure Functions

Use the following step-by-step instructions to deploy the SentinelOne Reports data connector manually with Azure Functions (Deployment via Visual Studio Code).

1. Deploy a Function App

NOTE: You will need to prepare VS code for Azure function development.

  1. Download the Azure Function App file. Extract archive to your local development computer.

  2. Start VS Code. Choose File in the main menu and select Open Folder.

  3. Select the top level folder from extracted files.

  4. Choose the Azure icon in the Activity bar, then in the Azure: Functions area, choose the Deploy to function app button. If you aren't already signed in, choose the Azure icon in the Activity bar, then in the Azure: Functions area, choose Sign in to Azure If you're already signed in, go to the next step.

  5. Provide the following information at the prompts:

    a. Select folder: Choose a folder from your workspace or browse to one that contains your function app.

    b. Select Subscription: Choose the subscription to use.

    c. Select Create new Function App in Azure (Don't choose the Advanced option)

    d. Enter a globally unique name for the function app: Type a name that is valid in a URL path. The name you type is validated to make sure that it's unique in Azure Functions. (e.g. SOneXXXXX).

    e. Select a runtime: Choose Python 3.8.

    f. Select a location for new resources. For better performance and lower costs choose the same region where Microsoft Sentinel is located.

  6. Deployment will begin. A notification is displayed after your function app is created and the deployment package is applied.

  7. Go to Azure Portal for the Function App configuration.

2. Configure the Function App

  1. In the Function App, select the Function App Name and select Configuration.

  2. In the Application settings tab, select ** New application setting**.

  3. Add each of the following application settings individually, with their respective string values (case-sensitive): SentinelOneAPIToken SentinelOneUrl WorkspaceID WorkspaceKey logAnalyticsUri (optional)

  • Use logAnalyticsUri to override the log analytics API endpoint for dedicated cloud. For example, for public cloud, leave the value empty; for Azure GovUS cloud environment, specify the value in the following format: https://<CustomerId>.ods.opinsights.azure.us.
  1. Once all application settings have been entered, click Save.
