Detailed explanation-1: -Remote Desktop Protocol (RDP) is a Microsoft proprietary protocol that enables remote connections to other computers, typically over TCP port 3389.

Detailed explanation-2: -Often, RDP servers are exposed directly to the Internet as this is a quick and easy way to provide remote access to distributed workers. Remote Desktop Protocol (RDP) servers should never be directly exposed to the Internet, where TCP port 3389 can be reached directly. This is a recipe for disaster.

Detailed explanation-3: -To be very clear… RDP should never be open to the Internet. The internet is continuously being scanned for open port 3389 (the default RDP port). Even with a complex password policy and multi-factor authentication you can be vulnerable to denial of service and user account lockout.

Detailed explanation-4: -Step 1: Enable Remote Desktop on your computer. Step 2: Open Remote Desktop port (port 3389) in Windows firewall. Step 3: Set up Port Forwarding (Port Translation) in the router. STEP 4: Map your dynamic IP to a hostname. STEP 5: Use Dynu DDNS service to access your computer remotely.
