Zero Trust Access to a Collection of RDP Servers
- Updated on Apr 19, 2023
Following Zero Trust principles, Banyan enables security policies to be applied at the granularity of a single RDP Server. However, organizations often maintain and manage multiple RDP servers, sometimes thousands, at a time. While some RDP servers require a unique set of access restrictions, many of them require identical access restrictions. Rather than configure each RDP server individually, you can group them and configure via a single service definition.
How it Works
Banyan uses standards-compliant HTTP Connect Tunneling and RD Gateway to enable connectivity to multiple services via a single RDP service definition.
In the Banyan Desktop App, the end user clicks Connect, which runs
banyanproxy in a special RD Gateway mode. The user has to update their Remote Desktop client’s RD Gateway configuration to point to this
When user enters the address of the Windows server they wish to RDP into, traffic is automatically sent by the RDP client to
banyanproxyrunning in HTTP Connect mode.
banyanproxyinitiates an MTLS connection with the Banyan service on the Netagent side at
rdpcollection.example.com:8443. Netagent checks the device posture and identity and, if successful, establishes the MTLS session.
banyanproxythen uses HTTP Connect to specify the actual destination of the request.
Netagent checks the Service Backend configurations for the
allow_patternsettings. If the connection request matches, Netagent makes the connection to the backend.
Once the connection is established, communication from the RDP client is as if it were directly connected to RDP server.
To configure Zero Trust Access to a Collection of RDP Servers:
1. Navigate to Manage Services > Infrastructure and click + Register Service. Then, select the template RDP Service.
2. On the service registration page, configure the Service Details.
3. Configure the remaining Service Attributes fields, making sure to set the method for how incoming connections should be proxied to the backend to Client specified using HTTP Connect.
4. In the Banyan Desktop App, locate the single entry (for this collection of RDP servers) and click Connect.
5. Open your preferred RDP client and access the applicable PC to which you are connecting. Or, create a new PC by adding the applicable backend IP. Then, add a gateway.
6. Enter the gateway name, which is the
banyanproxy from the Banyan Desktop App and then enter a Friendly Name (such as
7. Enter the user account credentials as needed.
8. You will be prompted to accept certificates for the RD Gateway and Client.
9. The RDP client will use
banyanproxy to automatically tunnel the RDP session over a Mutual-Auth TLS channel using HTTP Connect Tunneling.
Additional Configurations for Windows RDP Clients
We recommend the following additional Windows RDP client configurations to enhance user experience.
Enable the option to Allow me to save credentials.
Set If server authentication fails to Connect and don’t warn me.
In Connection settings:
- Select Use these RD Gateway server settings
- Set Logon method to Allow me to select later
- Enable Bypass RD Gateway server for local addresses.
In Logon settings, enable Use my RD Gateway credentials for the remote computer.
Then, enter your credentials and check the Remember me checkbox.
