Hi, we have a customer looking to move their CIFS file shares from a Windows Server to a NetApp.
There are currently using Windows Server's File Screening feature in Windows File Server Resource Manager to block certain file types. They would like to continue doing this when they move to the Netapp.
I understand FPolicy can do some screening, but that it can also integrate with File Screening Servers to get it's policy data ... can such a server be a Windows Server with the native Microsoft File Screening feature? If so does anyone know where I might find some documentation for setting this feature up?
When the NetApp Controller provides the CIFS Shares, there is no FSRM available. In order to use the FSRM feature within the Windows Server, it would need to support the FPolicy Feature/API of the NetApp Controller (which is not the case afaik).
You can setup basic file screening within the NetApp System. e.g. to block mp3 files from being stored:
options fpolicy.enable on
fpolicy create mp3blocker screen
fpolicy ext inc set mp3blocker mp3
fpolicy options mp3blocker required on
fpolicy monitor set mp3blocker -p cifs,nfs create,rename
fpolicy enable mp3blocker -f
PS In worst case they can keep using their Windows Server and attach a LUN to the NetApp (iSCSI/FC), then they can keep using the FSRM but loose the best snapshot technology in the world (or most of it)...
I can say block these File-extensions, file patterns AND when somebody try to Safe this file send an EMail to firstname.lastname@example.org with a warning an with the name/ip of the user who is trying to safe the ransomware data.
