Oracle Web content server (UCM) security for files generated from BI reports

Summary

Oracle Web content server security for files generated from BI reports

Content

 

We are running a BIP report which outputs the file to content server with security group as say FAFusionImportExport
We want to control user security who have access to a file or folder in content server. Please confirm the standard setup navigation to achieve this.

1) How can we know list of users who have access to security group FAFusionImportExport, How to manage/add/delete the access to this security group for a given user?

2) Can we create custom security group ? Because we want to have report output file wise security.
