The main reason I have used NSGs has been when deploying ADFS to Azure. Network security groups give the ability to configure rules and control inbound and outbound network traffic that can then be assigned to a single VM or a whole subnet and all the VMs within it. Using an NSG makes it possible to create a subnet with restricted access from the other Azure subnets and also on-premises network. Microsoft Azure allows administrators to control the traffic in subnets using the Network Security Group (NSG) feature. However when deploying infrastructure to Azure, this option is not available to administrators. On-premises we tend to deploy firewall appliances which are used to achieve this segmented networking infrastructure. If ($PSVersionTable.More and more enterprises are extending their datacentre to the cloud and making use of these resources to deploy ever more complex solutions. As with on-premises infrastructure, it is quite often necessary to setup up different security zones in the cloud i.e. Trusted and DMZ. # Check if running as Administrator (when not running from Cloud Shell), otherwise close the PowerShell window $global:currenttime= Set-PSBreakpoint -Variable currenttime -Mode Read -Action $bastionDiagnosticsName = "# The name of the new diagnostic settings for Bastion. $logAnalyticsName = # The name of your existing Log Analytics workspace. $rgLogAnalyticsSpoke = # The Azure resource group your existing Log Analytics workspace is deployed. $bastionPipName = # The public IP address of the Bastion resource. $nsgNameBastion = # The name of the NSG associated with the AzureBastionSubnet. $subnetBastionAddress = # The subnet must be at least /27 or larger. $subnetNameBastion = "AzureBastionSubnet" $vnetName = # The existing VNet in which the Bastion resource will be created. $rgNetworkSpoke = # The Azure resource group in which your existing VNet is deployed. $location = # The used Azure public region. $bastionName = # The name of the new Bastion resource. $rgBastion = # The new Azure resource group in which the new Bastion resource will be created. First adjust all variables to your use and afterwards run the script with Administrator privileges from Windows Terminal, Windows PowerShell, or Visual Studio Code.Īzure Bastion: Azure PowerShell deployment script To use the script copy and save it as Build-AzureBastion.ps1 or download it from GitHub. Before running the script logon with “Connect-AzAccount” and select the correct Azure Subscription.In the script change all variables were needed to fit your needs.At least Azure Az PowerShell module version 5.9.0 and Az.Network module version 4.7.0.Lock the Azure Bastion resource group with a CanNotDelete lock.Set the log and metrics settings for the bastion resource if they.Create the Bastion host (it can take up to 8 minutes for the Bastion host to be deployed), if it not already exists.Create a Public IP Address (PIP) for the Bastion host, if it not already exists.If the AzureBastionSubnet exists but does not have an associated NSG, it will attach the newly created NSG. The NSG itself will contain all the required inbound and outbound security rules.
