In the new blade, provide the credentials (username and password) and the cloud administrator can choose between opening the session on the existing browser or a new window (my recommendation), click on Connect.īehind the scenes, your browser is connected securely through port 443 in the Azure Bastion service. To use the service, in the properties blade of the desired VM, click on Connect and then on Bastion.Īnother method introduced recently is using the Connect item, which is located in the same VM’s properties. The subnet will be filled out automatically and create a new public IP address that will be used by the service.Īt this stage, we have configured the Azure Bastion service and we have placed a VM in the default subnet of the same virtual network. In the same location, we also need to select the virtual network. In the Create a Bastion blade, we need to define the resource group, name, and region. The final step is to create a new resource: Click on Create a resource or search for Bastion on the global search.
However, the current configuration configured in this section will be enough to get the service running. A network security group will be associated when we lock down the resource in the next section. You shouldn’t configure any route table to this subnet. The name of the new subnet must be AzureBastionSubnet, and the address range must use /27. Click on subnets in the virtual network blade, and click on Add Subnet.
#BASTION SECURITY HOW TO#
Here’s how to add the subnet required for the Azure Bastion service. If you don’t have enough room, for example, if your virtual network has an address space of 10.0.0.0/24, then it is recommended to increase it to /16 before moving forward. We need a /27 subnet to be added to the virtual network. The first step is to go to your virtual network and check the address space item and validate the current size of your virtual network. If you do have VPN/ExpressRoute or NVAs, you may have some layer of protection, but Azure Bastion is still a valid option to avoid all the RDP and jump boxes VMs on your environment. If you are a company that is exposing your VMs on the Internet, this is a perfect solution and also saves cost where no public IPs are required on your VMs to receive remote control on day-to-day operations. The only requirement is an HTML 5 browser. The solution is scalable, and there is no additional configuration from the cloud administrator and does not require any other software. The solution is deployed at the virtual network level. The second portion of the connection takes place inside of the protected virtual network, and communication from Azure Bastion on either port 22 (SSH, Linux) or 3389 (RDP, Windows) is required to connect. From the Azure Portal, the operator can connect using Azure Bastion, and that requires only a secure 443 port from the Azure Portal to the Azure Bastion host. The way the service works is simple but it provides an extra layer of security and protection for your infrastructure-as-a-service (IaaS) VMs running in Azure. Azure Bastion is a platform-as-a-service (PaaS) offering in Microsoft Azure that increases the security posture of your company by removing any RDP/SSH connections from the Internet to your VMs.
