some details on Clean file listing

in the Release Notes of Sophos Enterprise Console 5.0
(sec_50_rneng.html) we read

   Clean file listing

   This feature allows SophosLabs to create a list of files which have
   been verified as clean. When the endpoint computer identifies a
   file which has been verified as clean, it will allow it to bypass
   the file scanning component, greatly increasing performance.

   The main benefit is for Windows operating system files which are
   used during startup. By allowing these files to run without
   scanning we have reduced startup time considerably. ...

   The system will also build a list of files which have been scanned
   using the latest identities, which will be marked as clean until
   the next data update is available. These files will also be sent to
   the SophosLabs "cloud" to be added to the list of files the labs
   will consider adding to the verified clean files in the future.

   Unlike decision caching, which doesn't survive a restart, the new
   system will retain the list after restarting.

I looked for more information on this, but the doc seem not to have
further information on this.

It seems to be part of Sophos Live Protection, but does it have any
further configuration control? Who can offer further knowledge of
Clean file listing?

Thanks, Thomas
