Vendor installation instructions
Note
This connector uses Azure Functions to connect to the AWS SQS / S3 to pull logs into Microsoft Sentinel. This might result in additional data ingestion costs. Check the Azure Functions pricing page for details.
(Optional Step) Securely store 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.
Prerequisites
- Ensure AWS SQS is configured for the s3 bucket from which flow and auditable event logs are going to be pulled. In case, Illumio provides bucket, please contact Illumio support for sqs url, s3 bucket name and aws credentials.
- Register AAD application - For DCR (Data collection rule) to authentiate to ingest data into log analytics, you must use Entra application. 1. Follow the instructions here (steps 1-5) to get AAD Tenant Id, AAD Client Id and AAD Client Secret.
- Ensure you have created a log analytics workspace. Please keep note of the name and region where it has been deployed.
