Tables Ingested

This connector ingests data into the following tables:

Table	Selection Criteria	Transformations	Ingestion API	Lake-Only
Malware_Data_CL		?	✓	?
ThreatIntelligenceIndicator	SourceSystem startswith "Cofense Intelligence :"	✓	✓	✗

💡 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:

• Azure Subscription: Azure Subscription with owner role is required to register an application in azure active directory() and assign role of contributor to app in resource group.
• 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: Cofense Username and Password is required. See the documentation to learn more about API on the Rest API reference
• Microsoft Defender for Endpoints: Microsoft Defender for Endpoints License is required for SentinelToDefender function.

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.

NOTE: This connector uses Azure Functions to connect to the Cofense Intelligence APIs to pull its Threat Indicators and create Threat Intelligence Indicators into Microsoft Sentinel Threat Intelligence and create/update Threat Indicators in Cofense. Likewise, it also creates/updates Cofense Based Threat Indicators in Microsoft Defender for Endpoints. All this might result in additional indicator and 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.

STEP 1 - App Registration steps for the Microsoft Azure Active Directory Application

This integration requires an App registration in the Azure portal. Follow the steps in this section to create a new Azure Active Directory application:

1. Sign in to the Azure portal.
2. Search for and select Azure Active Directory.
3. Under Manage, select App registrations > New registration.
4. Enter a display Name for your application.
5. Select Register to complete the initial app registration.
6. When registration finishes, the Azure portal displays the app registration's Overview pane. You see the Application (client) ID and Tenant ID. The client ID and Tenant ID is required as configuration parameters for the execution of CofenseIntelligence Data Connector.

STEP 2 - Add a client secret for Microsoft Azure Active Directory Application

Sometimes called an application password, a client secret is a string value required for the execution of CofenseIntelligence Data Connector. Follow the steps in this section to create a new Client Secret:

1. In the Azure portal, in App registrations, select your application.
2. Select Certificates & secrets > Client secrets > New client secret.
3. Add a description for your client secret.
4. Select an expiration for the secret or specify a custom lifetime. Limit is 24 months.
5. Select Add.
6. Record the secret's value for use in your client application code. This secret value is never displayed again after you leave this page. The secret value is required as configuration parameter for the execution of CofenseIntelligence Data Connector.

STEP 3 - Assign role of Contributor to Microsoft Azure Active Directory Application

Follow the steps in this section to assign the role:

1. In the Azure portal, Go to Resource Group and select your resource group.
2. Go to Access control (IAM) from left panel.
3. Click on Add, and then select Add role assignment.
4. Select Contributor as role and click on next.
5. In Assign access to, select User, group, or service principal.
6. Click on add members and type your app name that you have created and select it.
7. Now click on Review + assign and then again click on Review + assign.

STEP 4 - Assign Defender Threat Indicator permissions to Microsoft Azure Active Directory Application

Follow the steps in this section to assign the permissions:

1. In the Azure portal, in App registrations, select your application.
2. To enable an app to access Defender for Endpoint indicators, assign it 'Ti.ReadWrite.All' permission, on your application page, select API Permissions > Add permission > APIs my organization uses >, type WindowsDefenderATP, and then select WindowsDefenderATP.
3. Select Application permissions > Ti.ReadWrite.All, and then select Add permissions.
4. Select Grant consent.
