Azure Network Interface
This page shows how to write Terraform and Azure Resource Manager for Network Interface and write them securely.
azurerm_network_interface (Terraform)
The Interface in Network can be configured in Terraform with the resource name azurerm_network_interface. The following sections describe 5 examples of how to use the resource and its parameters.
Example Usage from GitHub
resource "azurerm_network_interface" "nic1" {
name = "nic1"
location = var.location
resource_group_name = var.resource_group_name
ip_configuration {
name = "testconfiguration1"
resource "azurerm_network_interface" "nic_helselog_web" {
name = "nic-helselog-web"
location = azurerm_resource_group.rg_helselog.location
resource_group_name = azurerm_resource_group.rg_helselog.name
ip_configuration {
resource "azurerm_network_interface" "NIC_HaProxy" {
name = "NIC_HaProxy"
location = var.azure_location_Paris
resource_group_name = azurerm_resource_group.Ressource_Paris_HAProxy.name
ip_configuration {

Tips: Best Practices for The Other Azure Network Resources
In addition to the azurerm_network_security_group, Azure Network has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.
azurerm_network_security_group
Ensure to disable RDP port from the Internet
It is better to disable the RDP port from the Internet. RDP access should not be accepted from the Internet (*, 0.0.0.0, /0, internet, any), and consider using the Azure Bastion Service.
azurerm_network_security_rule
Ensure to set a more restrictive CIDR range for ingress from the internet
It is better to set a more restrictive CIDR range not to use very broad subnets. If possible, segments should be divided into smaller subnets.
azurerm_network_watcher_flow_log
Ensure to enable Retention policy for flow logs and set it to enough duration
It is better to enable a retention policy for flow logs. Flow logs show us all network activity in the cloud environment and support us when we face critical incidents.
Microsoft.Network/networkInterfaces (Azure Resource Manager)
The networkInterfaces in Microsoft.Network can be configured in Azure Resource Manager with the resource name Microsoft.Network/networkInterfaces. The following sections describe how to use the resource and its parameters.

Frequently asked questions
What is Azure Network Interface?
Azure Network Interface is a resource for Network of Microsoft Azure. Settings can be wrote in Terraform.
Where can I find the example code for the Azure Network Interface?
For Terraform, the azizbekmol/Terraform14, tirrrred/SP-IaC-Demo and etienne-plagnieux/Logskills_Terraform_Azure source code examples are useful. See the Terraform Example section for further details.
For Azure Resource Manager, the sewalshmsft/AzureTemplates, Azure/autorest.azureresourceschema and moothumk/clodun source code examples are useful. See the Azure Resource Manager Example section for further details.
