A Network Security Group.

Network security group(NSG): Displays which NSG is associated to the network interface(if any).

This article explains network security group concepts, to help you use them effectively.
Azure creates several default security rules within each network security group.

There are limits to thenumber of security rules you can create in a network security group.
A Network Security Group(NSG) is a basic stateful packet filtering firewall and it enables you to control access based on a 5-tuple.
High: A vulnerability exists with a meaningful resource(such as an application,a VM, or a network security group) and requires attention.
Each network security group contains rules, which allow or deny traffic to and from sources and destinations.
If you create a virtual machine on a cloud server, log in to the virtual machine's administrative background,set up a network security group.
VM4: Traffic is allowed to VM4, because a network security group isn't associated to Subnet3, or the network interface in the virtual machine.
The effective security rules for each network interface attached to a virtual machineare a combination of the rules you have created in a network security group and default security rules.
Define a single collection of rules using ASGs and Network Security Groups(NSG), you can apply a single NSG to your entire virtual network on all subnets.
When configuring virtual network peering,you can either open or close the network security group rules between the virtual networks. .
VM3: Since there is no network security group associated to Subnet2, traffic is allowed into the subnet and processed by NSG2, because NSG2 is associated to the network interface attached to VM3.
You cannot specify multiple IP addresses andIP address ranges in network security groups created through the classic deployment model.
An Azure network security group can contain multiple inbound and outbound security rules that enable you to filter traffic to and from resources by source and destination IP address, port, and protocol.
If you are unable to communicate to or from a virtual machine, network security group security rules or routes effective for a network interface, may be causing the problem.
For outbound traffic, Azure processes the rules in a network security group associated to a network interface first, if there is one, and then the rules in a network security group associated to the subnet, if there is one.
VM4: All network traffic is allowed from VM4, because a network security group isn't associated to the network interface attached to the virtual machine, or to Subnet3.
For inbound traffic, Azure processes the rules in a network security group associated to a subnet first, if there is one, and then the rules in a network security group associated to the network interface, if there is one.
