How to Activate the Bastion Service Pre-step: Create a separate Azure Subnet for Bastion In a nutshell Just-in-time (JIT) virtual machine (VM) access can be used to lock down inbound traffic to your Azure VMs, reducing exposure to attacks while providing easy access to connect to VMs when needed. This is something you could achieve with the also not so old service Just-in-time VM Access, it’s an Azure Security Center feature you can leverage. One other alternative way to reduce exposure to a brute force attack to your Azure Virtual Desktop environment is to limit (and IP whitelist – filter) the amount of time that a port is open. I’ve recorded a short video after writing and creating my Azure Bastion Service, and to give you a sneak preview on the end result of this blog article – I’ve uploaded a video to show you the easiness and value. The Bastion PM team is adding some new futures soon, such as Azure AD and MFA integration and recording mode directly from the service.This value lets Azure know which subnet to deploy the Bastion resources to. You must create a subnet using the name-value AzureBastionSubnet.

You must use a separate subnet in your virtual network to which the new Bastion host resource will be deployed.

If you create a bastion host in the portal by using an existing VM, various settings will automatically default corresponding to your virtual machine and/or virtual network.

Bastion can also be used for secure SSH connections to for example Linux resources in your Azure IaaS environment.

The Bastion Service is currently available for the following Azure DC regions.

Create a Bastion resource in the Azure portal by using existing VM settings.

Create a Bastion resource using the Azure portal.

There are two ways that you can create a Bastion host resource:.

Use this specific Preview – – URL to get access to the service.

The service operation from inside your Azure ARM portal.

See below how it works from an architecture perspective… Also to replace insecure steppingstone servers, as I mentioned earlier in this article! After that, the connection proceeds to the subnet in the Azure Virtual Network where the Bastion Service persists and connect via the NSG of the VMs you want to leverage internally over the Remote Desktop (3389) or SSH (22) ports.Ī secure way to access your Azure Virtual Desktop as well as infrastructure servers in your Azure Infrastructure-as-a-Service environment. Also, it doesn’t require you to expose any Public IP or Remote Desktop Services port on your Network Security Group (NSG) for the internet.Īzure Bastion works over port 443, this is the only port you need to open from the outside to the inside over the Network Security Group (NSG). This makes it easy and secure to go over corporate firewalls without any adjustments. The service automatically streaming to your local device via an RDP/SSH session over SSL on port 443. The service is completely HTML5 based and works from every modern web browser. Remote Access my Azure Virtual Desktop imagesĪzure Bastion is a new Azure Platform service you could leverage to enable external access to your resources in Azure Infrastructure-as-a-Service (IaaS).Deploy Azure Bastion from the Azure Marketplace.Create a separate Azure Subnet for Bastion In some simple configuration clicks – and most importantly without exposing any RDP (or SSH) ports to the outside internet – you can access your Azure Virtual Desktop Virtual Machines in Azure.Ĭurious about how to do this? Please continue reading… Table of ContentsĬlick on the title to jump to that spot in this article: Azure Bastion is completely web-based and works via SSL. “From an security perspective this is the most worst you can do, because once hackers are in – you’ve got access to almost everything!”Īzure Bastion is a relatively new Azure service that can simplify as well as improve remote connectivity – as a secure better alternative for stepping stone servers to your Azure Virtual Desktop – and infrastructure Virtual Machines on Microsoft Azure.

We all remember (and some of you still use them, unfortunately) stepping stone, or also called jump management servers to manage and maintain your Remote Desktop, or infrastructure server environment internally (and externally) through a Remote Desktop Connection with the most common reason it’s just easy?
