Configure Advanced SSL Options
You can select the security protocols that Horizon Client can use. You can also specify the cipher control
string.
Prerequisites
Verify the security protocol that the View server can use. If you configure a security protocol for
Horizon Client that is not enabled on the View server to which the client connects, an SSL error occurs and
the connection fails. For information about configuring the security protocols that are accepted by View
Connection Server instances, see the View Security document.
Horizon Client and View Connection Server support TLS v1.0 and TLS v1.1 by default. You should change
the security protocols in Horizon Client only if your View administrator instructs you to do so, or if your
View server does not support the current settings.
Procedure
1 Use the Horizon Client interface tools to display General Settings.
If you are using full-screen mode, tap the Horizon Client Tools icon and tap the settings icon. If you are
not using full-screen mode, tap the Settings icon in the upper-right corner of the screen.
2 Tap Advanced SSL Options.
3 Make sure that Use Default Settings is unchecked.
4 To enable or disable a security protocol, tap the check box next to the security protocol name.
TLS v1.0 and TLS v1.1 are enabled by default.
5 To change the cipher control string, replace the default string.
The default cipher control string (AES:!aNULL:@STRENGTH) includes cipher suites that use either 128-
bit or 256-bit AES encryption, except for anonymous DH algorithms, and sorts them by strength.
6 (Optional) If you need to revert to the default settings, tap to select the Use Default Settings option.
7 Tap OK to save your changes.
Your changes take effect the next time you connect to View Connection Server.
Supported Desktop Operating Systems
Administrators create virtual machines with a guest operating system and install View Agent in the guest
operating system. End users can log in to these virtual machines from a client device.
For a list of the supported Windows guest operating systems, see the "Supported Operating Systems for
View Agent" topic in the View 5.x or 6.x installation documentation.
