When migrating to Infrastructure-as-a-Service (IaaS), you are responsible for securing your environment.
This means you need to secure your network and services.
These processes were normally handled by your cloud provider within a Platform-as-a-Service (PaaS) or Software-as-a-Service (SaaS) environment.
Azure Security Center provides threat protection for data centers within both cloud workloads and on-premises.

Data Collection

Cortex XSIAM supports two methods to fetch alerts from Microsoft Defender for Cloud:

• Microsoft Defender for Cloud collector (API Collection).
• Azure Event Hub.

Microsoft Defender for Cloud collector

This collection method is more relevant in cases where the number of subscriptions is low, as each integration’s instance refers to one subscription.

For more information on how to configure this integration, refer to the integration’s docs:

1. Navigate to settings → Automation & Feed Integrations.

2. Search for Microsoft Defender for Cloud.
3. Click + Add instance.

Azure Event Hub

This collection method is more relevant in cases where the number of subscriptions is high, and you want to stream alerts at the tenant level.
Nevertheless, it supports alerts streaming at the subscription level as well.

Prerequisites

• Create an Azure event hub. For more information, refer to Microsoft’s official documentation.
• Make sure that you have permissions for the root management group.

Stream alerts with Continuous Export to Event Hub

Refer to the following links for detailed instructions:

• At the subscription level.
