The CrowdStrike Falcon Indicators of Compromise connector retrieves the Indicators of Compromise from the Falcon Intel API and uploads them Microsoft Sentinel Threat Intel.
Tables Ingested
This connector ingests data into the following tables:
| Table | Selection Criteria | Transformations | Ingestion API | Lake-Only |
|---|---|---|---|---|

💡 Tip: Tables with Ingestion API support allow data ingestion via the Azure Monitor Data Collector API, which also enables custom transformations during ingestion.
Permissions
Resource Provider Permissions:
- Workspace (Workspace): read and write permissions on the workspace are required.
- Keys (Workspace): read permissions to shared keys for the workspace are required. See the documentation to learn more about workspace keys.
Custom Permissions:
- 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.
- CrowdStrike API Client ID and Client Secret: CROWDSTRIKE_CLIENT_ID, CROWDSTRIKE_CLIENT_SECRET, CROWDSTRIKE_BASE_URL. CrowdStrike credentials must have Indicators (Falcon Intelligence) read scope.
Setup Instructions
⚠️ Note: These instructions were automatically generated from the connector's user interface definition file using AI and may not be fully accurate. Please verify all configuration steps in the Microsoft Sentinel portal.
STEP 1 - Generate CrowdStrike API credentials.
Make sure 'Indicators (Falcon Intelligence)' scope has 'read' selected
STEP 2 - Register an Entra App with client secret.
Provide the Entra App principal with 'Microsoft Sentinel Contributor' role assignment on the respective log analytics workspace. How to assign roles on Azure.
STEP 3 - Choose ONE from the following two deployment options to deploy the connector and the associated Azure Function
IMPORTANT: Before deploying the CrowdStrike Falcon Indicator of Compromise connector, have the Workspace ID (can be copied from the following).
- Workspace ID:
WorkspaceIdNote: The value above is dynamically provided when these instructions are presented within Microsoft Sentinel.
6. Option 1 - Azure Resource Manager (ARM) Template
Use this method for automated deployment of the CrowdStrike Falcon Adversary Intelligence connector connector using an ARM Tempate.
Click the Deploy to Azure button below.
Provide the following parameters: CrowdStrikeClientId, CrowdStrikeClientSecret, CrowdStrikeBaseUrl, WorkspaceId, TenantId, Indicators, AadClientId, AadClientSecret, LookBackDays
7. Option 2 - Manual Deployment of Azure Functions
Use the following step-by-step instructions to deploy the CrowdStrike Falcon Adversary Intelligence 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.
Download the Azure Function App file. Extract archive to your local development computer.
Start VS Code. Choose File in the main menu and select Open Folder.
Select the top level folder from extracted files.
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.
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. CrowdStrikeFalconIOCXXXXX).
e. Select a runtime: Choose Python 3.12.
f. Select a location for new resources. For better performance and lower costs choose the same region where Microsoft Sentinel is located.
Deployment will begin. A notification is displayed after your function app is created and the deployment package is applied.
Go to Azure Portal for the Function App configuration.
2. Configure the Function App
- In the Function App, select the Function App Name and select Configuration.
- In the Application settings tab, select ** New application setting**.
- Add each of the following application settings individually, with their respective string values (case-sensitive): CROWDSTRIKE_CLIENT_ID CROWDSTRIKE_CLIENT_SECRET CROWDSTRIKE_BASE_URL TENANT_ID INDICATORS WorkspaceKey AAD_CLIENT_ID AAD_CLIENT_SECRET LOOK_BACK_DAYS WORKSPACE_ID
- Once all application settings have been entered, click Save.
