Azure Event-Driven Harvesting
InsightCloudSec has the capability to augment standard polling-based harvesting along with Event-Driven Harvesting (EDH). For Azure, InsightCloudSec subscribes to control-plane change events using Azure’s EventGrid, which triggers targeted harvesting.
This dynamic approach to data collection both improves InsightCloudSec's cadence for providing resource visibility and opportunities for remediation, as well as enriches the data with lifecycle changes that enable auditing capabilities. With EDH-provided data, identifying how a resource entered a noncompliant state becomes much easier at scale.
Before you get started with EDH, you need to ensure you have the following:
- A basic understanding of the relevant Azure services
- Appropriate Azure permissions
- A strategy around the behaviors you want to use to configure EDH
If you have questions or encounter issues, reach out to us at through the Customer Support Portal.
For self-hosted customers, this feature is only supported using the Fargate ECS via Terraform deployment method. Additionally, regardless of your method of deployment, there are settings that must be configured prior to deployment to prevent issues with EDH functioning correctly. In general, for self-hosted customers interested in using Azure EDH we recommend connecting with your CSM or the Customer Support Portal prior to enabling this feature.
Understanding EDH Concepts
EDH relies on a relationship between a Producer and Consumer. InsightCloudSec requires a way to pull event data out of Azure Subscriptions and with minimal infrastructure required. This is done with a Service Bus queue. If the Subscription has a queue following our naming convention, ICS automatically labels the Azure Subscription as an EDH Consumer.
- Queue: Method for getting events out of the Subscription and into InsightCloudSec
- Consumer: Subscription that contains a queue
- Producer: EventGrid configuration that sends events to the queue
- ServiceApp Principal: credentials used to pull events from the queue
For a single Azure Subscription, InsightCloudSec consumes events from an Azure Service Bus queue which in turn subscribes to events from Azure’s EventGrid. For each additional Azure Subscription, an EventGrid subscription can be configured to forward events to the first Service Bus queue, allowing for InsightCloudSec to consume events from a single queue.
