One Identity Safeguard for Privileged Sessions 6.0 LTS - Administration Guide

Creating and editing protocol-level HTTP settings

HTTP settings determine the parameters of the connection on the protocol level, including timeout value, and so on.

To create a new HTTP settings profile or edit an existing one

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

   Figure 166: HTTP Control > Settings — Creating and editing protocol-level HTTP settings

   

2. Click to display the parameters of the profile.

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

   • Idle timeout: Timeout value for the session in seconds. To avoid early timeout, set it to a larger value, for example a week (604800 seconds).

     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.

   • Session timeout: Timeout value for the session in seconds.

   • 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.

     NOTE: This option cannot be disabled.

4. To distinguish the audited HTTP requests and responses based on the session cookies of web applications, click Session Cookie Settings > , and enter the name of the session cookie, for example, PHPSESSID, JSESSIONID, or ASP.NET_SessionId. Note that the names of session cookies are case sensitive.

   Repeat this step to add multiple cookie names. Note that if you list multiple cookie names, SPS will use the first one it finds to assign the requests to a session.

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

   Figure 167: <Protocol> Control > Settings > TLS security settings - configuring TLS security settings

   

   • Cipher strength specifies the cipher string OpenSSL will use. The following settings 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 in order to ensure compatibility with older systems. For more details on customizing this list, check the 'openssl-ciphers' manual page on your SPS appliance.

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

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

     • TLS 1.1: this setting will offer TLS version 1.1 and later versions during negotiation.

     • TLS 1.0: this setting will offer TLS version 1.0 and later versions during negotiation.

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

6. Click .

7. Select this settings profile in the HTTP settings field of your connections.

ICA-specific settings

The following sections describe configuration settings available only for the ICA protocol. Use the following policies to control who, when, and how can access the ICA connection.

• ICA connections: For details, see Setting up ICA connections.

• Channel Policy: The channel policy determines which ICA channels (for example clipboard, file-sharing, and so on) can be used in the connection, and whether they are audited or not. The different channels may be available only under certain restrictions, as set in the channel policy. For details, see Creating and editing channel policies.

• ICA settings: ICA settings determine the parameters of the connection on the protocol level, including timeout value and display parameters. For details, see Creating and editing protocol-level ICA settings.

• Deployment scenarios: These describe the available One Identity Safeguard for Privileged Sessions (SPS) deployment scenarios in a Citrix environment. For details, see One Identity Safeguard for Privileged Sessions (SPS) deployment scenarios in a Citrix environment

Setting up ICA connections

This section focuses on describing the ICA-specific details of connection configuration. For a detailed description on configuring connections, see General connection settings.

Reliable connection is also known as Common Gateway Protocol (CGP). It attempts to reconnect to the server in case of a network failure. To use this feature, enable Reliable and enter the default port in the Port field in the upper right corner.

Enable Act as SOCKS proxy to configure the client to use One Identity Safeguard for Privileged Sessions (SPS) as a SOCKS proxy. If you have enabled this option, you can select Inband destination selection as Target. Enter the IP address or the IP address/Prefix of the brokers (Citrix XML Brokers) used by the client in this connection policy into the Address field. It is also recommended to enable access to the brokers on port 443, as the clients usually try to access the broker using this port first. Disabling port 443 will cause a denied connection to appear on the SPS Search interface for every connection attempt (but the clients will be able to connect the server).

Supported ICA channel types

The available ICA channel types and their functionalities are described below. For a list of supported client applications, see Supported protocols and client applications.

• Drawing (Thinwire): Enables access to the server's desktop (screen). This channel is for remoting graphics and user input (keyboard, mouse). This channel must be enabled for ICA to work.

• Audio Mapping: Enable access to the sound device of the server.

• Drive Mapping: Enable access to the client's hard drives on the server.

• Clipboard: Enable access to the server's clipboard: the clipboard of the remote desktop can be pasted into local applications (and vice-versa). Note that One Identity Safeguard for Privileged Sessions (SPS) can audit the clipboard channel, but the Safeguard Desktop Player currently cannot search or display its contents.

• Smartcard: Enable using client side installed smartcards in server-side applications.

• Printer (COM1): Enable access to the serial port COM1.

• Printer (COM2): Enable access to the serial port COM2.

• Printer (LPT1): Enable access to the parallel port LPT1.

• Printer (LPT2): Enable access to the parallel port LPT2.

• Printer Spooler: Enable access to the client's printer from the remote desktops and applications.

• HDX Mediastream: Some user widgets (for example Flash player) will not run on the server but on the client. These widgets are controlled from the server side using this channel. This is not supported by Safeguard Desktop Player and it is disabled by default.

• USB: Enable using client side installed USB devices in server-side applications.

• Seamless: Enable seamless channels that run a single application on the ICA server, instead of accessing the entire desktop. When disabled, the application window will be accessed along with an empty desktop.

• Speedbrowse: Speeds up web browsing. Not currently supported by Safeguard Desktop Player, should be disabled by default.

• Custom: Applications can open custom channels to the clients connecting remotely to the server. Enabling the Custom channel allows the clients to access all of these custom channels. To permit only specific channels, enter the unique names of the channel into the Details field.
