What is RDP (Remote Desktop Protocol)?
Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft that provides a graphical interface for connecting to and controlling a remote computer over a network. RDP is commonly used to manage Windows-based servers and virtual machines in hosting environments.
How Does Rdp Work?
RDP works by transmitting the remote server's display output to the client while sending keyboard and mouse input back to the server. It operates on TCP port 3389 by default and supports features like clipboard sharing, audio redirection, multi-monitor display, and file transfer between the local and remote machines.
In web hosting, RDP is the primary method for administering Windows servers that run IIS, ASP.NET applications, or SQL Server databases. For security, administrators should change the default port, enable Network Level Authentication, use strong passwords, restrict access through firewall rules, and consider implementing a VPN to encrypt the RDP connection and reduce exposure to brute-force attacks.
