  X11 -- Client Request (Inbound)

Category: REMOTE-ACCESS      

Application: X11      

The X Window System (commonly X or X11) is a computer software system and network protocol that provides a graphical user interface (GUI) for networked computers.

This SonicWALL signature identifies legitimate, unencrypted X11 traffic. Due to its lack of encryption, it is advised that any remote X11 session should be done via an SSH tunnel.
