This article provides information on how to prevent users from changing Client Device Access Settings for 12.x Plug-in and later versions of Receiver for Windows using Client Selective Trust. Note: By default, all client device access are set to 0 (no access), users can still access the connection center and change Client Device Access values.

With Online Plug-in 12.x, client device access in ICA sessions formerly configured with the webica.ini file is now done with the registry key Client Selective Trust (HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA Client\Client Selective Trust) as described in CTX124921 – Citrix Online Plug-in 12.0 Ignores Webica.ini Settings.


In addition to specifying 0 for no access for all categories (File Security, MicrophoneAndWebcamSecurityPermission, PdaSecurityPermission, ScannerAndDigitalCameraSecurityPermission) in all zones (oidInternetRegionIcaAuthorizationDecision, oidIntranetRegionIcaAuthorizationDecision, oidRestrictedSitesRegionIcaAuthorizationDecision, oidTrustedSitesRegionIcaAuthorizationDecision), set the following value to False:


As a result, all fields in the connection center will be unavailable and users cannot change the security settings predefined by an administrator.
