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:

No-IP ( www.noip.com )
DynDNS ( www.dyndns.com )

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.
