What is the default RDP port for TCP/UDP?

The default port for Remote Desktop Protocol (RDP) is 3389. This port is standardized for RDP, which is a proprietary protocol developed by Microsoft primarily for remote management and virtual desktop access. When a user connects to a device through RDP, the communication typically occurs over this port, facilitating the transmission of keyboard and mouse inputs along with video output from the remote machine.

In addition, RDP on this default port allows secure connections, supporting encryption and authentication measures to protect the data being exchanged. It is widely recognized within network configurations, allowing both Windows systems and compatible client applications to establish remote desktop sessions without additional configuration.

Understanding this default port is crucial for network administrators when configuring firewalls, setting up VPNs, or troubleshooting connectivity issues related to remote access.
