App Control: Citrix App Layering Integration Not Approving Files

Products

• Carbon Black App Control (formerly Cb Protection)

Issue/Introduction

Citrix App Layering Integration is configured per guide, but files are not getting locally approved which is causing blocks.

Environment

• App Control Agent: All Supported Versions

Cause

The Citrix App Layering integration requires that the App Layering filter driver "unifltr.sys" is running. During publishing of a Layered Image, the driver is disabled by default unless the Elastic Layering option is enabled. 

Resolution

1. When creating an image in the Citrix App Layering console:
   • Select Create Template Wizard
   • Click Layered Image Disk
   • Elastic Layering must be set to "Application Layering" (the default is None)
