Quick answer: Secure RDP on a Windows VPS by using strong credentials, restricting the RDP firewall rule to known IP addresses, changing the default port to cut automated noise, enabling Network Level Authentication, setting an account-lockout policy, and keeping the server patched.
Remote Desktop (RDP) is how you administer a Windows VPS, which also makes it a favorite target for automated password-guessing attacks. An exposed RDP port with a weak password is one of the most common ways Windows servers get compromised. These steps lock it down without losing convenient access.
Set a long, unique password for every account with RDP access (16+ characters). Where possible, rename the default Administrator account and create a separate named admin account. This defeats bots that specifically target the "Administrator" username.
The most effective single change is to stop exposing RDP to the entire internet. In Windows Defender Firewall with Advanced Security, edit the inbound rule for Remote Desktop and scope it to your office or home IP address under the rule's Scope tab. Only those addresses can then reach the RDP port at all.
If your own IP changes often, a small management VPN or jump host is a better long-term answer than opening RDP to the world.
Moving RDP off the default port 3389 does not make it secure on its own, but it dramatically cuts the volume of automated noise hitting the server. Change the value in the registry, then open the new port in the firewall before disconnecting:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp\PortNumber
Add a firewall rule for the new port, restart the Remote Desktop Services, and connect using server-ip:newport.
Network Level Authentication (NLA) requires the user to authenticate before a full session is created, which blocks a class of pre-authentication attacks. Enable it in System Properties under the Remote tab by requiring computers to use Network Level Authentication.
Set an account lockout policy (for example, lock after 5 failed attempts for 15 minutes) so brute-force attempts stall instead of running indefinitely.
Apply Windows security updates promptly. Several serious RDP vulnerabilities have been fixed by patches over the years, and an unpatched server undoes the other steps.
What is the single most effective step?
Restricting RDP to your known IP addresses, so the port is not exposed to the whole internet.
Does changing the port make RDP secure?
Not on its own, but it sharply reduces automated attack noise; combine it with the other steps.
On a SoftSys managed Windows VPS, our team applies these hardening steps, manages the firewall, and keeps the server patched for you, so RDP stays both usable and protected. If you run your own server, the checklist above closes the doors attackers rely on.
