You can use RDP securely through SSL/TLS on Windows Vista, Windows 7, Windows 8, Windows 10, and Windows Server 2003/2008/2012/2016. The older versions of RDP are vulnerable to an attack called ‘ man-in-the-middle‘ that can result in the attacker gaining unauthorized access to your session. RDP operates within an encrypted channel, and each update improves the encryption methods. There are VNC applications for different operating systems, and there are no limits in using them to connect to different computers on different platforms. VNC is platform-independent and can be used across platforms. But many client-side applications let you use RDP on platforms such as Linux, Mac, iOS, and Android. Also on the server-side, it works only on Windows computers. RPD is a Windows original and comes pre-installed on Windows computers.
