Remote desktop protocols (RDPs) are used for connecting and interacting with computers remotely. In recent years, we have witnessed a number of vulnerabilities identified in two widely used remote desktop implementations, Microsoft Remote Desktop and RealVNC, that may expose the connected systems to a new attack vector. Such vulnerabilities are particularly concerning when it comes to mission-critical systems in which a client device with a low trust level connects to the critical system via a remote desktop server. In this preliminary study we propose a proxy-based solution that applies various modules, each of which mitigates a different type of threat, in order to secure remote desktop connections used in missioncritical systems.
