Description
The Cisco Duo Security data connector provides the capability to ingest [authentication logs](https://duo.com/docs/adminapi#authentication-logs), [administrator logs](https://duo.com/docs/adminapi#administrator-logs), [telephony logs](https://duo.com/docs/adminapi#telephony-logs), [offline enrollment logs](https://duo.com/docs/adminapi#offline-enrollment-logs) and [Trust Monitor events](https://duo.com/docs/adminapi#trust-monitor) into Microsoft Sentinel using the Cisco Duo Admin API. Refer to [API documentation](https://duo.com/docs/adminapi) for more information.

Connector instructions
Content published in the repository. Refer to the original file for all parameters.
>**NOTE:** This connector uses Azure Functions to connect to the Cisco Duo API to pull logs into Microsoft Sentinel. This might result in additional data ingestion costs. Check the [Azure Functions pricing page](https://azure.microsoft.com/pricing/details/functions/) 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](https://docs.microsoft.com/azure/app-service/app-service-key-vault-references) 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 [**CiscoDuo**](https://aka.ms/sentinel-CiscoDuoSecurity-parser) which is deployed with the Microsoft Sentinel Solution.
**STEP 1 - Obtaining Cisco Duo Admin API credentials**
1. Follow [the instructions](https://duo.com/docs/adminapi#first-steps) to obtain **integration key**, **secret key**, and **API hostname**. Use **Grant read log** permission in the 4th step of [the instructions](https://duo.com/docs/adminapi#first-steps).
**STEP 2 - Choose ONE from the following two deployment options to deploy the connector and the associated Azure Function**
>**IMPORTANT:** Before deploying the data connector, have the Workspace ID and Workspace Primary Key (can be copied from the following), as well as Azure Blob Storage connection string and container name, readily available.
Workspace ID
Primary Key
Option 1 - Azure Resource Manager (ARM) Template
Use this method for automated deployment of the data connector using an ARM Template.
1. Click the **Deploy to Azure** button below.
[](https://aka.ms/sentinel-CiscoDuoSecurity-azuredeploy) [](https://aka.ms/sentinel-CiscoDuoSecurity-azuredeploy-gov)
2. Select the preferred **Subscription**, **Resource Group** and **Location**.
3. Enter the **Cisco Duo Integration Key**, **Cisco Duo Secret Key**, **Cisco Duo API Hostname**, **Cisco Duo Log Types**, **Microsoft Sentinel Workspace Id**, **Microsoft Sentinel Shared Key**
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 data connector manually with Azure Functions (Deployment via Visual Studio Code).
Step 1 - Deploy a Function App
1. Download the [Azure Function App](https://aka.ms/sentinel-CiscoDuoSecurity-functionapp) file. Extract archive to your local development computer.
2. Follow the [function app manual deployment instructions](https://github.com/Azure/Azure-Sentinel/blob/master/DataConnectors/AzureFunctionsManualDeployment.md#function-app-manual-deployment-instructions) to deploy the Azure Functions app using VSCode.
3. After successful deployment of the function app, follow next steps for configuring it.
Step 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):
CISCO_DUO_INTEGRATION_KEY
CISCO_DUO_SECRET_KEY
CISCO_DUO_API_HOSTNAME
CISCO_DUO_LOG_TYPES
WORKSPACE_ID
SHARED_KEY
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://WORKSPACE_ID.ods.opinsights.azure.us`.
4. Once all application settings have been entered, click **Save**.
