It can be wrought with challenges and security issues if not managed and configured correctly. Creating a VPN connection is a viable option for accessing Azure internal VMs. VPN connections have been around for decades now. Click the Create button.Īzure Bastion connection to a Windows Server 2022 virtual machine 2. Search in the Azure portal for Bastion and it will bring up the Azure Bastions configuration. As a note, to use the Bastion host, you will need to be logged into the Azure portal. Setting up the Azure Bastion host is simple as well. That means all the security burden of the Azure bastion host is taken on by Microsoft which is great.

That’s right, it isn’t a VM you have to stand up, maintain, and secure. This alleviates the need to stick everything that you need to access on the Internet and greatly diminishes the attack surface of the internal VMs hosting resources.Īs you noticed, we called this a PaaS service. This is a relatively newer service from Microsoft that allows users to access internal VMs without using an external IP address on the internal virtual machines. Virtual Private Network (VPN) connectionĪrguably, the preferred way to access Azure VM from outside is the Azure Bastion host PaaS service.

Let’s take a look at the following ways how to Access Azure VM from outside. It simply minimizes the attack surface and makes it more difficult for an attacker to compromise an environment. The fewer resources you place on the Internet, the better.

After all the Colonial Pipeline attack was learned to have started with breached VPN credentials found in a breached password list. Breached password lists readily available on the dark web or public Internet can also contain real passwords used by others, potentially in your organization. Sticking a virtual machine, no matter how secure, out on the Internet is poking a hole in your defenses.Įven if your VM is fully patched, what if an attacker has possession of credentials of a user who has been granted access to that resource? Today, many attacks begin with a phishing attack that harvests credentials. One of the first tenants of good cybersecurity is minimizing the attack surface. Some may wonder, if I have everything secured even with very strong passwords, why do I need to worry about putting virtual machines and other cloud resources out on the public Internet with a public IP. Specifically, in Azure, let’s look at how to access Azure VM from outside and see what mechanisms you can leverage to do that. However, this can create grave security concerns that are not ideal for any organization with today’s high-profile ransomware and other cybersecurity threats. How do engineers, developers, contractors, and others access environments from the outside? The first tendency of course is just to throw a public IP on everything and allow access this way. Because this is a part of our Landing Zone, I import this resource into this Terraform script.When it comes to architecting cloud IaaS environments, one of the issues that always comes to the forefront after standing up infrastructure is access. For this a central Log Analytics Workspace can be used. When we deploy new resources we need to be able to catch the diagnostic settings for these resources. Note that recently the subnetmask for this subnet changed to /26.

Feel free to adjust it to fit your ip addressing.Īs you can see in my screenshot I already deployed the “AzureBastionSubnet” in my Hub vnet. In this case I’m deploying the Bastion in my Hub vnet. The first resource that you need is your vnet.

In this blogpost I’ll show you how to deploy an Azure Bastion into an already existing Hub-Spoke Virtual Network with Terraform.Įxisting resources that you need before deploying this code With this solution your virtual machines don’t need a public ip address anymore. Because security is very important, Microsoft developed a PaaS Service “ Azure Bastion” to connect secure to your virtual machines over port 22 and port 3389.
