8.1.3.2 Ensure that 'Vulnerability assessment for machines' component status is set to 'On' (Manual)
Description
Enable vulnerability assessment for machines on both Azure and hybrid (Arc enabled) machines.
Rationale
Vulnerability assessment for machines scans for various security-related configurations and events such as system updates, OS vulnerabilities, and endpoint protection, then produces alerts on threat and vulnerability findings.
Impact

- From Azure Home select the Portal Menu.
- Select
Microsoft Defender for Cloud.
- Under
Management, select Environment Settings.

Vulnerability assessment for machines is set to On.
Repeat the above for any additional subscriptions.
From Azure Policy:
- Policy ID:
501541f7-f7e7-4cd6-868c-4190fdad3ac9 - Name: 'A vulnerability assessment solution should be enabled on your virtual machines'
Expected Result
Vulnerability assessment for machines should be set to On.
Remediation
From Azure Portal:
- From Azure Home select the Portal Menu.
- Select
Microsoft Defender for Cloud.
- Under
