1. Understanding Remote Desktop Protocol (RDP)
Definition of Remote Desktop Protocol:
Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft which enables users to connect to another computer over a network connection. It provides a graphical interface, allowing users to
access screens
and interact with the remote computer as if they were physically present. RDP facilitates the transmission of screen visuals, keyboard inputs and mouse movements between the client and server.
Common Uses for RDP:
-
Remote Work:
Professionals can access their office computers from home or while travelling, ensuring uninterrupted productivity.
-
IT Support:
Technicians can remotely troubleshoot and resolve issues on client machines, reducing the need for on-site visits.
-
Accessing Personal Files:
Users can retrieve and manage files stored on their home computers from any location, providing flexibility and convenience.
2. Preparing the Target Computer
To allow RDP connections, the target computer must be configured appropriately. Below are the standard steps for different operating systems:
Enabling Remote Desktop:
A. Windows Systems
-
Enable Remote Desktop:
-
Press
Win + I
to open
Settings
.
-
Navigate to
System
>
Remote Desktop
.
-
Toggle the
Enable Remote Desktop
switch to
On
.
-
Confirm the action if prompted.
-
Allow Remote Desktop Through Windows Firewall:
-
In the
Start
menu, type
Windows Firewall
and select
Windows Defender Firewall
.
-
Click on
Allow an app or feature through Windows Defender Firewall
.
-
Ensure that
Remote Desktop
is checked for both
Private
and
Public
networks.
-
Click
OK
to apply the changes.
B. macOS Systems
While macOS doesn't natively support RDP, users can access Windows PCs from a Mac using the Microsoft Remote Desktop client:
-
Download Microsoft Remote Desktop:
-
Visit the Mac App Store and download
Microsoft Remote Desktop
.
-
Set Up a Remote Connection:
-
Open the
Microsoft Remote Desktop
app.
-
Click on the
Add PC
button.
-
Enter the
PC Name
(the IP address or hostname of the Windows computer).
-
Configure additional settings as needed and click
Add
.
-
Double-click the PC you just added to initiate a connection.
C. Android Devices
Android devices can connect to Windows PCs using the Microsoft Remote Desktop app:
-
Install the App:
-
Download and install Microsoft Remote Desktop from the Google Play Store.
-
Configure the Connection:
-
Open the app and tap the
+
icon to add a new connection.
-
Select
Add PC
.
-
Enter the
PC Name
(IP address or hostname of the target computer).
-
Input
User Account
information or choose to prompt for credentials upon connection.
-
Save the settings.
-
Initiate the Connection:
-
Tap on the saved PC name to start the remote session.
-
Enter the necessary credentials when prompted.
Firewall Settings:
To allow RDP connections through the firewall:
-
Windows Firewall:
-
Open
Control Panel
>
System and Security
>
Windows Defender Firewall
.
-
Click on
Allow an app or feature through Windows Defender Firewall
.
-
Ensure
Remote Desktop
is enabled for the appropriate network profiles.
-
Third-Party Firewalls:
-
Refer to the specific software's documentation to allow traffic on port
3389
, the default port for RDP.
NB:
Remember that opening RDP out to other networks and to the Internet exposes your servers to all manners of cyber-threats. Security (
firewall and more
) is therefore paramount.
3. Network Configuration Methods
When connecting to a remote computer on a different network via RDP, the correct network configuration is essential. Below are two common methods to establish a secure connection: using a Virtual Private Network (VPN) or configuring Port Forwarding.
A. Using Virtual Private Network (VPN)
A VPN creates a secure, encrypted tunnel between the client and the remote network, allowing for direct and secure access without exposing RDP to the open internet.
Setup Process:
-
Choose a VPN Solution
-
Use a third-party VPN service like
NordVPN, OpenVPN, WireGuard or Cisco AnyConnect
.
-
Or, if you prefer self-hosting, set up a
VPN server on a router or Windows Server
.
-
Install VPN Software
-
For third-party VPNs, download and install their respective client software.
-
For self-hosted VPNs, configure a
VPN server
on the remote network.
-
Configure VPN Access
-
If using Windows, navigate to
Settings
>
Network & Internet
>
VPN
>
Add a VPN connection
.
-
Input the
server address
, protocol, and credentials provided by your VPN service.
-
Connect and Verify
-
Once connected to the VPN, you can access the remote machine using its
local IP address
(e.g.,
192.168.1.100
).
-
Launch the
Remote Desktop Connection (RDC) client
and enter the local IP.
Advantages of Using VPN
Enhanced Security
– Keeps RDP traffic encrypted and hidden from the internet.
Prevents Direct Exposure
– Eliminates the need for public IP exposure or port forwarding.
Bypasses ISP Restrictions
– Some ISPs block RDP traffic, but VPNs can circumvent these blocks.
That said, RDS-Tools provides a
secure control of computers over RDP
, whatever the network.
B. Port Forwarding
Port forwarding allows external RDP traffic to reach a specific computer by mapping an open port on the router to an internal machine.
Router Configuration:
-
Find the Local IP of the Target Computer
-
Open
Command Prompt
on the target machine and type:
ipconfig
-
Note the
IPv4 Address
(e.g.,
192.168.1.100
).
-
Access Router Settings
-
Enter the router’s admin panel by typing
192.168.1.1
(or
192.168.0.1
) in a web browser.
-
Log in with admin credentials.
-
Set Up Port Forwarding
-
Navigate to
Advanced Settings
>
Port Forwarding
.
-
Add a new rule:
-
Service Name
: RDP
-
Protocol
: TCP
-
External Port
: 3389 (or custom)
-
Internal Port
: 3389
-
Internal IP
: Enter the local IP (
192.168.1.100
).
-
Save and apply changes.
-
Find Public IP & Connect
-
Visit
WhatIsMyIP
to find your
public IP
.
-
On the client machine, use
Remote Desktop Connection
to connect using:
Public_IP:3389
Dynamic DNS (DDNS)
Since public IPs change frequently,
Dynamic DNS (DDNS)
assigns a persistent hostname (e.g.,
myremotecomputer.ddns.net
). Popular DDNS providers include:
Most routers support
DDNS configuration
, allowing you to use a stable hostname instead of checking your public IP.
Security Risks & Mitigation Strategies
Risk:
Exposing RDP to the Internet
– Attackers frequently scan for open RDP ports.
Solution:
-
Change the
default RDP port
(3389) to something unique (e.g.,
44500
).
-
Restrict RDP access to
specific IPs
using firewall rules.
-
Use
multi-factor authentication (MFA)
for added protection.
4. Establishing the RDP Connection
Once the remote computer and network configurations are set, you can establish the connection.
Client-Side Setup
Using Remote Desktop Clients
-
Windows:
Use the built-in
Remote Desktop Connection (mstsc)
.
-
Mac:
Install
Microsoft Remote Desktop
from the
Mac App Store
.
-
Android & iOS:
Use Microsoft Remote Desktop from Google Play Store.
Connection Process
-
Launch Remote Desktop Client
-
On Windows, open
Remote Desktop Connection
(
mstsc
).
-
Enter the
IP Address
(or hostname if using DDNS).
-
Click
Connect
.
-
Authenticate Credentials
-
Enter the
username & password
of the remote machine.
-
Click
OK
and accept any security prompts.
-
Control the Remote Computer
-
The desktop of the remote PC will appear.
-
You can now
operate the computer as if you were physically present
.
5. Enhancing Security for Remote Connections
Strong Authentication
-
Use a
complex password
with at least
12 characters
(mix of uppercase, lowercase, numbers, and symbols).
-
Enable
Multi-Factor Authentication (MFA)
for additional security.
Network Level Authentication (NLA)
NLA ensures authentication occurs
before
the connection is established.
To enable NLA:
-
Open System Properties
(
Win + R
, type
sysdm.cpl
).
-
Go to the
Remote
tab.
-
Under
Remote Desktop
, check
"Allow connections only from computers running Remote Desktop with Network Level Authentication"
.
Changing Default RDP Ports
Attackers often target
port 3389
, so changing it reduces brute-force attempts.
To change the RDP port:
-
Open
Registry Editor
(
regedit
).
-
Navigate to:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp
("System" and "Server"
-
Find
PortNumber
, right-click, select
Modify
.
-
Change
Base
to
Decimal
, then enter a new port (e.g.,
44500
).
-
Restart the computer for changes to take effect.
Regular Updates
-
Always
install Windows security updates
to fix vulnerabilities.
-
Keep
firewall & antivirus software up to date
.
-
Disable
RDP access
when not needed.
