Security remains an important concern in cloud computing. A network security group (NSG) is one way of protecting a group of cloud resources. The NSG provides a set of security rules or virtual firewall for those resources. The NSG can apply to an individual VM, a network interface card (NIC) for that VM, or even a subnet. The NSG is essentially a layer around the VM, subnet, or other cloud resource, as part of a layered defense strategy. This gives the customer some additional control over security.
