Vendor installation instructions

Note

This connector uses Azure Functions to connect to the Amazon S3 REST API to pull logs into Microsoft Sentinel. This might result in additional data ingestion costs. Check the Azure Functions pricing page for details.

Note

This connector has been updated to support cisco umbrella version 5 and version 6.

(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 Functions App.

Note

This connector uses a parser based on a Kusto Function to normalize fields. Follow these steps to create the Kusto function alias Cisco_Umbrella.

STEP 1 - Configuration of the Cisco Umbrella logs collection

See documentation and follow the instructions for set up logging and obtain credentials.

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

IMPORTANT: Before deploying the Cisco Umbrella data connector, have the Workspace ID and Workspace Primary Key (can be copied from the following), as well as the Amazon S3 REST API Authorization credentials, readily available.
