With console access lacking in Azure and many planned features on the road map, for the most part, I’m really excited about the service. It’s then from the Jumpbox that remote access can be gained across the network peerings. The Bastion host sits in the hub VNet which it shares with a Jumpbox, in essence replacing the need for a secure VPN connection. Further research of various blogs and community chat suggest that support for peered VNets is another feature also being explored.įor now, when trying to access VMs attached to VNets in unsupported regions or for customers that don’t wish to deploy a Bastion host for each VNet, the workaround is to simply adopt a hub-spoke network architecture. The service roadmap highlights plans to add great capabilities like Azure AD integration, Seamless Single-Sign-on and Multi-Factor Authentication to the service. It is also only possible to deploy a Bastion host within a single VNet. Whether VNets have been implemented due to project segmentation, business unit, location and so on, it’s very rare to encounter an enterprise customer that does not have to control VMs sprawled over multiple VNets.Īt the time of writing, limitations of the Bastion service mean that it does not yet support VNet peering.

It’s continuously hardened by automatically patching and keeping up to date against known vulnerabilities.

Hardening in one place to protect against zero-day exploits: Azure Bastion is a managed service maintained by Microsoft.

Increased protection against port scanning: The limited exposure of virtual machines to the public Internet will help protect against threats, such as external port scanning.

Simplified secure rules management: Simple one-time configuration of Network Security Groups (NSGs) to allow RDP/SSH from only Azure Bastion.

No public IP required on Azure Virtual Machines: Azure Bastion opens the RDP/SSH connection to your Azure virtual machine using a private IP, limiting exposure of your infrastructure to the public Internet.

Remote session over SSL and firewall traversal for RDP/SSH: HTML5 based web clients are automatically streamed to your local device providing the RDP/SSH session over SSL on port 443.

RDP and SSH from the Azure portal: Initiate RDP and SSH sessions directly in the Azure portal with a single-click seamless experience.

Key features available during the public preview include: The service does this without having to configure each VM with its own public endpoint. Bastion is a new managed PaaS service that provides seamless RDP and SSH connectivity for your VMs over Secure Socket Layer (SSL).

In answer to this problem, Microsoft has released in public preview the Azure Bastion service. In efforts to reduce risk, security features such as MFA, Just in Time Access (JiT) and ACL can be implemented, but this can be difficult to manage and not totally infallible. Amongst other things, it’s possible to use port scanning to discover the public IP and then brute force attacks to compromise the machine. The problem with adding public endpoints directly to a host or even to a Jumpbox is that it makes them susceptible to malicious attacks. Another option is to only allow remote access from a trusted private network over an inter-site connection such as a site-to-site VPN or ExpressRoute.Įither way, enterprises are forced to compromise security or impact the user’s experience, limiting where they can access from or by forcing them to traverse numerous network levels to gain access to the required service. This is normally achieved using Remote Desktop Protocol (RDP) and Secure Shell (SSH) sessions connected over public IP addresses, either directly assigned to individual hosts or a shared Jumpbox.

A common headache facing customers migrating workloads to the public cloud is deciding how best to provide secure remote access to Windows and Linux VMs.
