How To Azure Ipsecurityrestrictions Powershell

How To Articles

As an IT professional, I have found PowerShell to be an incredibly powerful tool for managing Azure resources. One important aspect of securing Azure resources is by using IP security restrictions to control access. In this article, I will provide a detailed guide on how to use PowerShell to implement IP security restrictions in Azure.


Before we dive into the PowerShell commands, make sure you have the following prerequisites in place:

  • An Azure subscription
  • Azure PowerShell module installed
  • Permissions to manage network security group rules in Azure

Connecting to Azure

First, we need to connect to Azure using PowerShell. Open PowerShell and run the following command:


This will open a dialog prompting you to sign in to your Azure account. Once you are signed in, your PowerShell session will be authenticated to your Azure account.

Retrieve the Network Security Group

Next, we need to retrieve the Network Security Group (NSG) to which we want to add IP security restrictions. Use the following command to get the NSG:

$nsg = Get-AzNetworkSecurityGroup -ResourceGroupName "YourResourceGroup" -Name "YourNSGName"

Replace “YourResourceGroup” with the actual resource group name and “YourNSGName” with the actual NSG name.

Add IP Security Restriction

Now, let’s add an IP security restriction rule to the NSG. The following command will allow traffic only from a specific IP address:

Add-AzNetworkSecurityRuleConfig -NetworkSecurityGroup $nsg -Name "AllowMyIP" -Description "Allow my IP address" -Access Allow -Protocol * -Direction Inbound -Priority 100 -SouceAddress "YourIPAddress" -SourcePortRange * -DestinationAddress * -DestinationPortRange *

Replace “YourIPAddress” with the actual IP address from which you want to allow traffic. The priority parameter is used to specify the order of the rule.

Apply the Changes

After creating the security rule configuration, we need to update the NSG with the new rule. Use the following command to update the NSG:

Set-AzNetworkSecurityGroup -NetworkSecurityGroup $nsg

Once you run this command, the IP security restriction rule will be added to the NSG.


Implementing IP security restrictions in Azure using PowerShell provides fine-grained control over network traffic. By following the steps outlined in this article, you can ensure that only authorized IP addresses have access to your resources, enhancing the overall security of your Azure environment.
