Remote Desktop Protocol (RDP) is one of the most widely used tools for remote access in UAE businesses — and one of the most frequently misconfigured. When set up correctly, RDP allows employees to connect directly to their office desktop computers from home or any remote location, accessing all locally installed software, files, and network resources exactly as if they were sitting at their desk in the office. For busines ses in industries such as accounting, engineering, and architecture, where specific desktop software is used, RDP is often the preferred remote access method.
However, poorly configured RDP is also a leading cause of cyberattacks in the UAE and globally. Exposing RDP directly to the internet without proper security controls makes your systems a target for brute-force attacks, ransomware, and unauthorised access. This guide explains how to set up RDP securely for UAE SMEs.
Step 1 — Enable Remote Desktop on the target computer: On the PC you want to access remotely, go to Settings > System > Remote Desktop, and toggle "Enable Remote Desktop" to On. Click Confirm. Note that Remote Desktop is only available on Windows 10/11 Pro, Enterprise, and Education editions — it is not available on Windows Home editions.
Step 2 — Note the computer's name and IP address: While in Remote Desktop settings, note the PC name shown. Also, open Command Prompt and type ipconfig to find the local IP address. You will need this to connect.
Step 3 — Connect from a remote device: On the device you want to connect from, open the Remote Desktop Connection application (search for "Remote Desktop Connection" in the Start menu). Enter the PC name or IP address and click Connect. You will be prompted for the Windows username and password of the remote computer.
Step 4 — Use the Remote Desktop app for mobile: Microsoft offers free Remote Desktop apps for iOS and Android, allowing employees to connect to their office PC from a smartphone or tablet. Download from the App Store or Google Play, configure a new PC connection with the address and credentials, and connect.
The most critical aspect of RDP security is ensuring that it is never exposed directly to the internet. Never open TCP port 3389 (the default RDP port) on your router or firewall to allow direct internet access. This is a configuration that attackers specifically scan for. Instead, always use one of these secure approaches:
Option 1 — VPN + RDP: Connect to the office VPN first, then use RDP over the VPN tunnel. This is the safest approach and the one Al Aida IT recommends for all IT AMC clients in Dubai. The RDP traffic stays within the encrypted VPN tunnel and is never exposed to the internet.
Option 2 — Remote Desktop Gateway: A Remote Desktop Gateway server allows RDP connections over HTTPS (port 443), eliminating the need to expose port 3389. This is a more complex setup but suitable for organisations that cannot use a VPN.
Option 3 — Azure Virtual Desktop: For Microsoft 365 customers, Azure Virtual Desktop provides a cloud-hosted desktop experience accessible from any browser or device, without any RDP port exposure.
Additionally, always enable Network Level Authentication (NLA) for RDP, use strong passwords on all accounts with RDP access, enable account lockout policies after failed login attempts, and consider changing the default RDP port from 3389 to a non-standard port number.
The most common issue with RDP connections is being blocked by Windows Firewall. If you cannot connect, ensure that "Remote Desktop" is allowed through Windows Firewall on the target computer. Go to Windows Defender Firewall > Allow an app through Firewall > Remote Desktop, and enable both Private and Public checkboxes.
Another common issue is connecting when the target computer is asleep or in hibernate mode. Configure the target PC's power settings to prevent sleep when plugged in — go to Power & Sleep Settings and set "When plugged in, PC goes to sleep after" to Never.
