hi @Jafar_Hussain 

 

yes this is possible in multiple ways:

 

you can restrict access via security rules or security profiles:

  • in the security rules you could block access to a server completely (block rule),
  • or only allow certain applications. some applications are even split up in file sharing 'child' applications and other functionality, so you could allow some functionality but block file transfers
  • additionally you can add file blocking profiles that prevent some or all filetypes from being transmitted in one direction or both: you could set up a security rule that allows a file transfer application, but then add a security profile (file blocking profile) that only allows uploads and blocks downloads

Thanks for the information.

First of all, i can not block completely server access. i need to block only copy files from the server or to the server.

I have tried to block the copy file by the file blocking profile but still i am able to copy file via VPN.

Below is the configuration description that I already tried.

 

File blocking profile:-

Security rule:-

 

Source zone - GP zone, inside zone

user - any

Source address Address - Any

Destination Zone - GP zone, Inside zone

Application - ms-rdp

Service - Any

Action - Allow

Profile - File blocking test

 

This scenario i tried but unable to block.

ah yes RDP

Microsoft put in some nifty (and prorietary) encryption that prevents the firewall from blocking files being copied

you can, however, control which actions are allowed by users in the RDP configuration tself on the server, so you can push out Global Policies that prevent files from being copied when users are connected via RDP (and have users use SMB instead, which you can control)

As per my understanding, you are saying we need to block only smb application from the Paloalto?

Mainly, we need to prevent users from copying files from shared folders to their systems when they access through VPN. Also, i want to know, how to do that for access over RDP.

no: you can't block file transfer via RDP in the firewall because microsoft built in an encryption that can't be deciphered by the firewall

 

it IS possible to disable filetransfer through RDP via GPO :
