Creating and editing protocol-level Telnet settings

Procedure

Telnet settings determine the parameters of the connection on the protocol level, including timeout value, and so on. Complete the following procedure to create a new Telnet settings profile or edit an existing one:

Caution:

Modifying the Telnet settings is recommended only to advanced users. Do not modify these settings unless you exactly know what you are doing.

To create and edit protocol-level Telnet settings

  1. Navigate to the Settings tab of the Telnet Control menu item and click to create a Telnet setting profile. Enter a name for the profile (for example telnet_special).

  2. Click to display the parameters of the connection.

  3. Modify the parameters as needed. The following parameters are available:

    • Network idle timeout: Connection timeout value in seconds. To avoid early timeout, set it to a larger value, for example a week (604800 seconds).

      Even if the user is not active, the session can contain activity that must be audited (for example, the output of a script). The idle timeout period will start only after this activity has stopped.

      Caution:

      Determining if a connection is idle is based on the network traffic generated by the connection, not the activity of the user. For example, if an application or the taskbar of a graphical desktop displays the time which is updated every minute, it generates network traffic every minute, negating the effects of timeout values greater than one minute and preventing One Identity Safeguard for Privileged Sessions (SPS) from closing the connection.

    • User idle timeout: If no user activity is detected, terminate the session after the configured time has passed since the last user activity.

      This can be useful if only user-generated network traffic is important in a session. By using this option, situations described in the caution of Network idle timeout (such as a taskbar clock keeping the network traffic open indefinitely) can be avoided. To enable user idle timeout, select Enable user idle timeout and enter a value that is greater than or equal to the value of Network idle timeout.

    • Enable pre channel check: Select this option to evaluate the connection and channel policies before establishing the server-side connection. That way if the connection is not permitted at all, SPS does not establish the server-side connection.

    • To configure TLS security settings on both the Client side and the Server side, proceed to TLS security settings.

      Figure 257: <Protocol> Control > Settings > TLS security settings - configuring TLS security settings

      • Cipher strength specifies the cipher string OpenSSL will use. The following options are possible:

        • Recommended: this setting only uses ciphers with adequate security level.

        • Custom: this setting allows you to specify the list of ciphers you want to permit SPS to use in the connection. This setting is only recommended to ensure compatibility with older systems. For more details on customizing this list, check the 'openssl-ciphers' manual page on your SPS appliance.

          For example: ALL:!aNULL:@STRENGTH

      • Minimum TLS version specifies the minimal TLS version SPS will offer during negotiation. The following options are possible:

        • TLS 1.2: this setting only offers TLS version 1.2 during the negotiation. This is the recommended setting.

        • TLS 1.1: this setting offers TLS version 1.1 and later versions during the negotiation.

        • TLS 1.0: this setting offers TLS version 1.0 and later versions during the negotiation.

        NOTE: Setting up sessions to legacy systems that do not support at least TLS 1.2 is only possible when the security level of the connection is degraded to 0, which is possible by specifying the TLS ciphers manually and appending the string `:@SECLEVEL=0` to the cipher list. However, this setting also enables the use of known vulnerable algorithms and key sizes, therefore it is absolutely critical to only use such connection settings when it is necessary and when you can fully trust your network between SPS and the legacy system. It is strongly recommended to use different security settings on the server and the client side of the connection, when degrading the security level of a connection is unavoidable.

      NOTE: Note that SPS only permits TLS-encrypted connections. SSLv3 is not supported.

  4. Click .

  5. To display a banner message to the clients before authentication, enter the message into the Banner field. For example, this banner can inform the users that the connection is audited.

  6. Select this settings profile in the TELNET settings field of your connections.

Inband destination selection in Telnet connections

When using inband destination selection in Telnet connections, the user can provide the server address and the username using the following methods:

  • By setting the TELNET ENVIRON option using the SERVER environment variable in the server:port format.

  • By setting the TELNET ENVIRON option using the USER environment variable in the user@server:port format.

  • If neither the SERVER nor the USER environment variable, One Identity Safeguard for Privileged Sessions (SPS) displays a terminal prompt where the user can enter the username and the server address.

VMware Horizon View connections

The following sections describe how to use One Identity Safeguard for Privileged Sessions (SPS) to control and audit VMware Horizon View (formerly known as VMware View) connections. When using SPS to control and audit VMware Horizon View connections, the following requirements and restrictions apply:

  • Only connections using the Remote Desktop (RDP) display protocol are supported. Connections using the PCoIP or HP Remote Graphics Software display protocols are not supported.

  • Both direct connections and tunnel connections are supported.

  • The VMware Horizon View connections must pass SPS directly. It is best if SPS is deployed directly before the Virtual Desktops accessed with VMware Horizon View, and connections are configured in transparent mode.

    Deploying SPS that way has the advantage of auditing connections even if the clients access the Virtual Desktops directly, without using a View Connection Server.

    NOTE: Using non-transparent mode is also possible if the VMware Horizon View traffic is routed to SPS with an external device (for example, a firewall).

SPS treats VMware Horizon View connections that satisfy these criteria as common RDP connections. All the features of SPS that are available for RDP connections can be used with VMware Horizon View connections as well, for example, four-eyes authorization, auditing and replaying, indexing the recorded audit trails, and so on. For details on RPD-specific settings, see RDP-specific settings.

One Identity Safeguard for Privileged Sessions (SPS) deployment scenarios in a VMware environment

One Identity Safeguard for Privileged Sessions (SPS) supports a variety of deployment scenarios, which make it really flexible when it comes to deployment. The following network topologies illustrate typical SPS VMware Horizon View deployment scenarios.

Client - Broker - SPS - Server

SPS is deployed between the Broker and the virtual desktop, where the RDP traffic is embedded into a HTTPS tunnel between the Client and the Broker.

Figure 258: Client - Broker - SPS - Server

Client - SPS - Server

SPS is deployed between the Client and the virtual desktop, the client makes a direct RDP connection to the Server, without tunneling it through the Broker.
