MS WBT Server

MS-WBT-SERVER, commonly known as Remote Desktop Protocol (RDP), is a Microsoft protocol that enables users to connect to another computer over a network. It is widely used for remote administration and troubleshooting. RDP provides a graphical interface to the user for remote access.

What is MS WBT Server

MS-WBT-SERVER, more commonly referred to as Remote Desktop Protocol (RDP), is a proprietary protocol developed by Microsoft. It allows users to connect to another computer over a network connection, providing a graphical interface to the remote user. This service is extensively used in corporate environments for remote administration, troubleshooting, and accessing virtual desktops.

RDP was first introduced with Windows NT 4.0 Terminal Server Edition and has since become a staple in Windows operating systems. It supports multiple features such as encryption, smart card authentication, and the ability to use multiple displays. The protocol operates over TCP port 3389 and can also be configured to use UDP for better performance.

One of the key advantages of RDP is its ability to provide a seamless experience for remote users, allowing them to access applications and data as if they were physically present at the remote machine. This has made it an essential tool for IT administrators and support teams. However, due to its widespread use and the potential for unauthorized access, it is crucial to secure RDP connections with strong passwords, multi-factor authentication, and network-level authentication.

MS WBT Server runs on TCP and UDP port 3389 and is official IANA port.

Security risk

If port 3389 is open and the RDP service is running, it can be a significant security risk. Unauthorized users could potentially gain access to the network, leading to data breaches, malware infections, and other malicious activities. It is essential to secure RDP with strong authentication methods and limit access to trusted IP addresses.

In our UFW tutorial you can follow instructions how you can configure UFW to close port 3389. Use StackChanges to monitor if the MS WBT Server port is closed and stays closed. StackChanges will send an alert if port 3389 is open again.
