Once the file scan has run on the reference system(s) you will have a list of all executables in the Windows directories that are not contained in a security catalog.

You can create a file parameter collection that contains this list of files which can then be used in a whitelist policy.

Create a file parameter collection by doing the following steps:

1. In the Security Manager Console, click the Policies tab.
2. In the left pane, navigate to the Arellia Solutions > Application Control > Filters > Inventory Filters.
3. Right-click the Inventory Filters folder.
4. Click New > File Scan Results Filter (Policy).
   
5. Give the filter a name and optional description.
6. Click OK.
   
   
   
   
7. In the Right pane, set the Data Source to the new policy.
8. Next to Reporting Filter click the Select link and choose the reporting filter you configured in the previous steps.
9. Under Results click Included.
10. Click Save.
