Mention the NSG Name and respective Resource Group Name and in the last Export-Csv Path name. There are no additional charges for creating network security groups in Microsoft Azure.Įxport the NSG rules to excel is very easy with below Azure Powershell command. While inbound NAT rules are functionally equivalent to endpoints, Azure recommends using network security groups for new deployments where NAT features (like port translation) are not required. In the Resource Manager deployment model, traffic can be controlled by using either network security groups or load balancers with inbound NAT rules.

In the Classic deployment model, endpoints - with access control lists (ACLs) - were used to control traffic in and out of virtual machines.

These default rules can be overriden by specifying rules with a lower priority number. All other traffic is automatically denied. There is also a rule to allow traffic originating from Azure's load balancer probe. Each network security group has a set of default security rules, which allows all traffic within a virtual network and outbound traffic to the internet. A network security group has separate inbound and outbound rules, and each rule can allow or deny traffic. Security rules are evaluated in priority-order, starting with the lowest number rule, to determine whether traffic is allowed in or out of the network interfaces or subnets associated with the network security group.

It contains a set of security rules that allow or deny inbound and outbound traffic using the following 5-tuple: protocol, source IP address range, source port range, destination IP address range, and destination port range. A network security group is a layer of security that acts as a virtual firewall for controlling traffic in and out of virtual machines (via network interfaces) and subnets.
