Azure_VirtualNetworks_26

Ensure that Azure Virtual Network subnet is configured with a Network Security Group

Description

Azure Virtual Network subnets should be associated with Network Security Groups. NSG provides the controls to facilitate a formal process for approving and testing all network connections and changes to the firewall and router configurations. NSG enables better control over network traffic to all resources within a subnet. As a best practice it is recommended to associate an NSG with a subnet to protect your VMs on a subnet-level.
