  • If GACS is used, then the GACS setting is applied on Citrix Enterprise Browser.
  • If GACS is not used, then Citrix Enterprise Browser displays the setting Ask.

For more information on GACS, see Manage Citrix Enterprise Browser through Global App Configuration service.

Clipboard restriction for security groups

You can restrict clipboard access to any designated group of apps. These designated groups of apps are created as security groups so that the end users are permitted to copy and paste contents only within that security groups. To enable clipboard access within the apps in a security group, you must just have an access policy configured with the action allow or allow with restrictions without selecting any access setting.

• When the Security groups restriction is enabled, you cannot copy / paste data between applications in different security groups. For example if the app “ProdDocs” belongs to security group “SG1” and the app “Edocs” belong to security group “SG2”, you cannot copy / paste content from “Edocs” to “ProdDocs” even if Copy / Paste restriction is enabled for both groups.

• For apps not part of a security group, you can have an access policy created with action allow with restrictions and selecting the restrictions (Copy, Paste, or Clipboard). In this case, the app is not part of a security group and the Copy / Paste restriction can be applied on that app.

Note:

You can also restrict clipboard access for apps accessed via Citrix Enterprise Browser through the Global App Configuration service (GACS). If you are using GACS to manage Citrix Enterprise Browser, then use the Enabled Sandboxed Clipboard option to manage the clipboard access. When you restrict clipboard access through GACS, it applies to all apps accessed via Citrix Enterprise Browser.

To create a security group, perform the following steps:

1. In the Secure Private Access console, click Applications and then click Security groups.
2. Click Add a new security group.

1. Enter a name for the security group.
2. In Add web or SaaS applications, choose the applications that you want to group to enable the copy and paste control. For example, Wikipedia, Pinterest and Dribble.
3. Click Save.

For details on Advanced clipboard settings, see Enable copy / paste controls for native applications and unpublished apps.

When end users launch these applications (Wikipedia, Pinterest and Dribble) from Citrix Workspace, they must be able to share data (copy / paste) from one application to the other applications within the security group. The copy / paste occurs irrespective of other security restrictions that are already enabled for the applications.

However, end users cannot copy and paste content from their local applications on their machines or unpublished applications to these designated applications and conversely. The following notification appears when the content is copied from the designated application into another application:

Note:

You can copy and paste the contents between the apps in a security group and other local apps on the machines or unpublished web apps by using the options in Advanced clipboard settings. For details, see Enable copy / paste controls for native applications and unpublished apps.

Enable granular level clipboard access

You can enable granular level clipboard access within the applications in a designated group. You can do so by creating access policies for the applications and enabling the Copy / Paste restriction as per your requirement.

Note:

Ensure that the specific access policy that you have created for granular level clipboard access has a higher priority than the policy that you have created for the security groups.

Example:

Consider that you have created a security group with three applications namely, Wikipedia, Pinterest, and Dribble.

Now, you want to restrict the pasting of content from Wikipedia or Dribble into Pinterest. To do so, perform the following steps:

1. Create or edit an access policy assigned for the application Pinterest. For details on creating an access policy, see Create access policies.
2. In the Step 3: Action page, select Allow with restrictions.
3. Select Paste.

Although Pinterest is part of a security group which also contains Wikipedia and Dribble, users cannot copy content from Wikipedia or Dribble to Pinterest because of the access policy associated with Pinterest in which the Paste restriction is disabled.

Enable copy / paste controls for native applications and unpublished apps

You can copy and paste the contents between the apps in a security group and other local apps on the machines or unpublished web apps by using the options in Advanced clipboard settings

1. Create a security group. For details, see Clipboard restriction for security groups.

2. Expand Advanced clipboard settings.

   

3. Select any of the following options as per your requirement:

   • Allow copying of data from the security group to unpublished domains – Enable copying of data from applications in the security groups to the apps that are not published in Secure Private Access.
   • Allow copying of data from the security group to native apps - Enable copying of data from the applications in the security groups to the local applications on your machines.
   • Allow copying of data from the unpublished domains to the security group – Enable copying of data from the apps not published through Secure Private Access to the applications in the security groups.
   • Allow copying of data from native apps operating system the security group - Enable copying of data from local applications on the machines to the applications.

Known issues

• The routing table in (Settings > Application Domain) retains the domains of a deleted application. Hence, these applications are also considered as published applications in Secure Private Access. If these domains are accessed directly from Citrix Enterprise Browser, copy / paste is disabled from these applications irrespective of the options that you have selected in Advanced clipboard settings.

  For example, assume the following scenario:

  • You have deleted an application named Jira2 (https://test.citrite.net) that was part of a security group.
  • You have enabled the option Allow copying of data from the security group to unpublished domains.

  In this scenario, if the user tries to copy data from this application into another application in the same security group, the pasting control is disabled. A notification regarding the same is displayed to the user.

• For a SaaS app, the app access can be denied if the application is configured with an access policy with action Deny access. The end users can still access the app because the app traffic is not tunneled through Secure Private Access. Also, if the application is part of the security group, the security group settings are not honored and hence you cannot copy /paste content from the application.
