You need a firewall somewhere. i.e. at your edge router.

Best practice is to always enable firewalls on all devices. Why do you want to disable the Windows Firewall?

Author

Commented:
I don't want to disable firewall , other administrators do that! I always need to check if is off or on,can i activate firewall only for 1 applicatiion? e.g.: rdpguard , i mean windows firewall is OFF but is activated only for rdpguard?

Commented:
You would have to create a rule or rules i.e. allow from any to any and the ports that rdpguard  doesn't use.  There should be a corporate policy about enabling/disabling firewalls

rdpguard works perfect but only when windows firewall is ON , sometimes i check and is OFF and i click ON again etc...

Allow ALL but 3389 so rdpguard can manage 3389 TCP allow all but 3389You might want to consider making a group policy preference that does this AND also keeps WF running

Author

Commented:
and if i follow ur tutorial rdpguard will block atacks even if WINDOWS FIREWALL will be OFF ??

Author

Commented:
yes but we use port 3389 to connect if we block 3389 then we can't connect anymore

Commented:
I didn't say block 3389 that is covered by another rule just ALLOW other ports

no windows firewall must be ON. If you use a group policy preference even if someone turns off the firewall it will be enabled when the group policy refreshes.

Commented:

rdpguard changes the settings for RDP in the firewall. So I don't understand your last statement

Author

Commented:
if windows firewall is turn off then rdpguard has no effect anymore,so i need turn on manually , rdpguard not turns on firewall
Commented:
There are several applications out there.  I use one called syspeace.  They all require a firewall to work.  

disabling the firewall is BAD.  Don't allow other people to do it.  

You need to focus on leaving the firewall turned on rather than protecting RDP while the firewall is off.  

Creating a rule to allow all traffic (except RDP) is not good because it opens the door for many attacks such as SMB attacks.

Commented:
then what is the solution?is there a way to set a rule to turn on firewall if is turned off?i think this is the 1 option,but i don't know how to do that so plz help me with that

Commented:
As previously mentioned, use Group policy to ensure the firewall remains on.

Commented:

Commented:
Here is a link to using group policy to control the firewall

As other experts have said you can implement the Windows firewall from GPO. That is a good practice because you have centralized control but it can be very, very labor intensive because typically software installations will auto write/allow rules for Windows Firewall. With GPOs you have to manually create them. So you definitely need a nesting policy like a Base and then explicits, which will override the Base policy on a per server or group basis. This practice should not be your primary defense but rather your perimeter firewall (hardware) should be and RDP should not be allowed (accessible) at the perimeter of the network, EVER - its a well known and documented security vulnerability. If you have a need for RDP for specific users then RDP over VPN. If you have a company wide need you should be looking at an RDS solution, which includes, at minimum, a Gateway, Broker, and Licensing server and Session Host/s. Depending on the size of the deployment they can consolidate or break them up as your needs & Best Practices dictate.
