Remote Desktop Protocol (RDP) is a proprietary graphical remote desktop software developed by Microsoft. It is the default solution for connecting to remote Windows servers and has been packaged with every version of Windows since XP. Now on its 8th version, RDP has been forked to work on most popular operating systems including IOS, Android, Mac, Windows, and Linux. Though designed to work with windows server, RDP has become a popular choice for connecting not just to remote PCs, but to mac as well as Linux servers.
Remote Desktop Protocol is designed to allow users to connect to a computer desktop remotely and access that computer as if it were right in front of them. A desktop connected has access to all plugged in peripherals just like a normal computer. These peripherals can include things like:
Remote Desktop Protocol uses the very well-known 3389 port, which is commonly used to infect computers with malware and ransomware. According to an article published by cybersecurity firm McAfee, RDP was the most common attack mechanism used to spread ransomware in Q1 2019.
For this reason, experts generally warn against using it over the Internet despite encryption capabilities. It is rather suggested to use RDP over a private network or VPN.
Despite security issues with port 3389, RDP does come with encryption enabled. Even peripherals like mouse and keyboard have their signals sent over encryption which although leading to input lag, helps to secure input such as passwords.
RDP is available on almost all platforms thanks to the open-source community and their efforts creating RDP software designed to work with operating systems like Linux.
The 2 leading open-source RDP protocols are FreeRDP and Xrdp. These can be installed on any Linux operating system and accessed through either Microsoft’s own Remote Desktop application on Windows or through open-source viewers like Rdesktop on Linux.
