A NSG is an access control list inside Azure where you can add inbound and outbound rules. When a connection is established between VMS, VNets, or other cloud services, this list is checked to see whether the connection is allowed or denied.
NSGs can be applied to one or more subnets or individual network interfaces (NIC). This means that all resources that are associated with this subnet or NIC will automatically have all the rules applied.
NSG rules are processed in priority order, with lower numbers before higher numbers, and they can be applied to inbound or outbound traffic.
