Prerequisites

To integrate with Digital Shadows Searchlight (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: Digital Shadows account ID, secret and key is required. See the documentation to learn more about API on the https://portal-digitalshadows.com/learn/searchlight-api/overview/description.

Vendor installation instructions

Note

This connector uses Azure Functions to connect to a 'Digital Shadows Searchlight' 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.

STEP 1 - Configuration steps for the 'Digital Shadows Searchlight' API

The provider should provide or link to detailed steps to configure the 'Digital Shadows Searchlight' API endpoint so that the Azure Function can authenticate to it successfully, get its authorization key or token, and pull the appliance's logs into Microsoft Sentinel.

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

IMPORTANT: Before deploying the 'Digital Shadows Searchlight' connector, have the Workspace ID and Workspace Primary Key (can be copied from the following), as well as the 'Digital Shadows Searchlight' API authorization key(s) or Token, readily available.

Option 1 - Azure Resource Manager (ARM) Template

Use this method for automated deployment of the 'Digital Shadows Searchlight' connector.

  1. Click the Deploy to Azure button below.

    Deploy To Azure

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

  3. Enter the Workspace ID, Workspace Key, API Username, API Password, 'and/or Other required fields'.

Note: If using Azure Key Vault secrets for any of the values above, use the@Microsoft.KeyVault(SecretUri={Security Identifier})schema in place of the string values. Refer to Key Vault references documentation for further details. 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 'Digital Shadows Searchlight' connector manually with Azure Functions.

  1. Create a Function App

  2. From the Azure Portal, navigate to Function App.

  3. Click + Create at the top.

  4. In the Basics tab, ensure Runtime stack is set to python 3.8.

  5. In the Hosting tab, ensure Plan type is set to 'Consumption (Serverless)'. 5.select Storage account

  6. 'Add other required configurations'.

  7. 'Make other preferable configuration changes', if needed, then click Create.

  8. Import Function App Code(Zip deployment)

  9. Install Azure CLI

  10. From terminal type az functionapp deployment source config-zip -g <ResourceGroup> -n <FunctionApp> --src <Zip File> and hit enter. Set the ResourceGroup value to: your resource group name. Set the FunctionApp value to: your newly created function app name. Set the Zip File value to: digitalshadowsConnector.zip(path to your zip file). Note:- Download the zip file from the link - Function App Code

  11. Configure the Function App

  12. In the Function App screen, click the Function App name and select Configuration.

  13. In the Application settings tab, select + New application setting.

  14. Add each of the following 'x (number of)' application settings individually, under Name, with their respective string values (case-sensitive) under Value: DigitalShadowsAccountID WorkspaceID WorkspaceKey DigitalShadowsKey DigitalShadowsSecret HistoricalDays DigitalShadowsURL ClassificationFilterOperation HighVariabilityClassifications FUNCTION_NAME logAnalyticsUri (optional) (add any other settings required by the Function App) Set the DigitalShadowsURL value to: https://api.searchlight.app/v1 Set the HighVariabilityClassifications value to: exposed-credential,marked-document Set the ClassificationFilterOperation value to: exclude for exclude function app or include for include function app

Note: If using Azure Key Vault secrets for any of the values above, use the@Microsoft.KeyVault(SecretUri={Security Identifier})schema in place of the string values. Refer to Azure Key Vault references documentation for further details.

  • 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.
