Explanation

An Azure Network Security Group is essentially a stateful packet‐filtering firewall at the virtual network level. It holds security rules - each specifying source/destination IP, port, protocol, and whether to allow or deny - that govern all inbound and outbound traffic for the subnets or network interfaces it's applied to. This lets you centrally enforce network-level access control without modifying individual VMs or applications.
