Description

Enable automatic discovery and configuration scanning of the Microsoft Kubernetes clusters.

Rationale

As with any compute resource, Container environments require hardening and run-time protection to ensure safe operations and detection of threats and vulnerabilities.

Impact

Agentless discovery for Kubernetes requires licensing and is included in:

• Defender CSPM
• Defender for Containers plans.

Audit

From Azure Portal

1. From the Azure Portal Home page, select Microsoft Defender for Cloud.
2. Under Management select Environment Settings.
3. Select a subscription.
4. Under Settings > Defender Plans, click Settings & monitoring.
5. Locate the row for Agentless discovery for Kubernetes.
6. Ensure that On is selected.

Repeat the above for any additional subscriptions.

Default Value

By default, Microsoft Defender for Containers is Off. If Defender for Containers is enabled from the Microsoft Defender for Cloud portal, auto provisioning will be enabled.
