RDP in Bastion Mode

This chapter contains an example of a basic Fudo Enterprise configuration, to monitor RDP access to a remote server. In this scenario, the user connects to the remote server in bastion mode by specifying the user name along with account login on the target server and target server address in the login string. Bastion mode enables facilitating privileged accounts monitoring while preserving default protocols port numbers.

Adding a user

User defines a subject entitled to connect to servers within monitored IT infrastructure. Detailed object definition (i.e. unique login and domain combination, full name, email address etc.) enables precise accountability of user actions when login and password are substituted with a shared account login credentials.


  1. Select Management > Users.

  2. Click Add.

  1. Click i to generate the proxy server’s private key or i to upload the .PEM file private key definition.

Note

For security reasons the form displays server’s public key derived from the generated or uploaded private key.

  1. Click Save.


Adding an account

Account defines the privileged account existing on the monitored server. It specifies the actual login credentials, user authentication mode: anonymous (without user authentication), regular (with login credentials substitution) or forward (with login and password forwarding); password changing policy as well as the password changer itself.

  1. Select Management > Accounts.

  2. Click Add.

  11. Click OK.

  12. Click Save.


Establishing an RDP Connection with a Remote Host

  1. Launch RDP client of your choice.

  2. Enter destination host IP address and RDP service port number.

  3. Enter user name along with account login on the target server (server login) and target server address (john_smith#admin#10.0.35.54) and provide password.

Note

When connecting using the forward account, where the user name and server login are identical, the server login field may be omitted (e.g., john_smith##10.0.35.54).

../../_images/rdp_client_user_credentials.png

Note

  • In case you do not specify login credentials, Fudo Enterprise will display the internal login screen to enter the account name along with the username and password.

  • When connecting using the forward account, where the Username and Server login are identical, the Server login field may be omitted on the login screen.

  • In case the specified account is not found, Fudo Enterprise will try to match the name with a server object. If a matching server is not found, system tries to match the string to a host’s DNS name.

  • Fudo Enterprise enables using a custom logo on the login screen for RDP and VNC connections. For more information refer to the Resources topic.

Viewing User Session

  1. Open a web browser and enter the Fudo Enterprise administrator panel IP address.

Note

Make sure that the entered IP address has the control panel sharing option enabled in the Network configuration settings.
