The following security methods are available: Negotiate: The Negotiate method enforces the most secure method that is supported by the client. If you enable this policy setting, all communications between clients and RD Session Host servers during remote connections must use the security method specified in this setting. Here are the notes from Microsoft on this policy: This policy setting specifies whether to require the use of a specific security layer to secure communications between clients and RD Session Host servers during Remote Desktop Protocol (RDP) connections. Step 5: A better idea -> Force TLS insteadĮdit the 'Require use of specific security layer for remote (RDP) connections' policy. As of writing this, the protocol involved for RDP traffic is RC4. Low: The Low setting encrypts only data sent from the client to the server by using 56-bit encryption.Īn important note: This only pertains to the connections that use the native RDP encryption. Use this encryption level in environments that include clients that do not support 128-bit encryption. Client Compatible: The Client Compatible setting encrypts data sent between the client and the server at the maximum key strength supported by the client. Clients that do not support this encryption level cannot connect to RD Session Host servers. Use this encryption level in environments that contain only 128-bit clients (for example, clients that run Remote Desktop Connection). The following encryption methods are available: High: The High setting encrypts data sent from the client to the server and from the server to the client by using strong 128-bit encryption. By default, the encryption level is set to High. Here are the notes for the different options that Microsoft Provides If you enable this policy setting, all communications between clients and RD Session Host servers during remote connections must use the encryption method specified in this setting. Then select 'Set client encryption level' and edit that policy Step 4: Require the Highest native Encryption possible.Įdit the 'Set client encryption level' policy.

In the sidebar Navigate to Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Hosts > Security. Select 'Local Computer' - this should be the default - and select 'Finish' > 'Ok.' Step 3: Navigate to the RDP Session Security Policies Select 'Group Policy Editor' and 'Add' the selected snap-in. Step 2: Open the Group Policy Editor Snap-in Select the top application, which will open the system console. Open the search bar and type 'mmc' or run mmc.exe from the Run application. This post will walk through the steps required to force TLS encryption on all RDP connections. In a shocking oversight this connection does not use strong encryption by default. Windows Remote Desktop Protocol (RDP) is widely used by system administrators trying to provide remote operators access to internal systems and servers.
