Question

You have received an email from your company security team that a couple of VMs are exposed to the internet, how to prevent that public access without interruption of any service?

Answer 1

In that case, you need to create the NSG and associate your VMs if there is no NSG. Now, block the port 80/443 and allow only specific ports of azure which will fix the issue.

Click on the VMs

Click on the networking tab

Click on the NSG

Then create the Outbound deny rule for the internet.
