Description

Enable automatic vulnerability management for images stored in ACR or running in AKS clusters.

Rationale

Agentless vulnerability scanning will examine container images - whether running or in storage - for vulnerable configurations.

Impact

Agentless container vulnerability assessment 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 container vulnerability assessment.
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.
