Configure Advanced TLS/SSL Options
You can select the security protocols and cryptographic algorithms that are used to encrypt
communications between Horizon Client and Horizon servers and between Horizon Client and the agent
in the remote desktop.
By default, TLSv1.0, TLSv1.1, and TLSv1.2 are enabled. SSL v2.0 and 3.0 are not supported. The default
cipher control string is "!aNULL:kECDH+AESGCM:ECDH+AESGCM:RSA+AESGCM:kECDH
+AES:ECDH+AES:RSA+AES".
If you configure a security protocol for Horizon Client that is not enabled on the Horizon server to which
the client connects, a TLS/SSL error occurs and the connection fails.
For information about configuring the security protocols that are accepted by Connection Server
instances, see the View Security document.
Procedure
1 Tap the Settings (gear) icon in the upper-right corner of the Horizon Client window and tap Security
options.
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.
5 To change the cipher control string, replace the default string.
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 the server.
Supported Desktop Operating Systems
A Horizon administrator creates virtual machines that have a guest operating system and installs agent
software 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 View Installation document.

Horizon Client for Chrome OS is a Chrome OS app, and you install it just as you do other Chrome OS
apps.
