What does X11 forwarding do?
X is a system and protocol that lets remote computers push interactive windows to your local computer over a network. We use a method known as X-Forwarding, together with an SSH client, to direct the network messages for X over the same connection you use for the command-line.

How does X11 forwarding work in SSH server?
In an X11 session, the server can send X11 commands back to the client. X11 was not designed with security in mind, it was designed with the idea that all programs that you’re displaying are run by you and hence trusted anyway. By default, SSH subjects commands from the server to restrictions through the X11 SECURITY extension.
How does X11 forwarding work in a text session?
With X11 forwarding, the server is likely to gain shell access to the client. In a text session, there is a limited channel from the server back to the client: the server determines the output that is displayed on the client, and can in particular try to exploit escape sequences in the terminal running on the client,
What kind of encryption is used in X11?
All X11 protocol is encrypted. The level of encryption can be set as needed. User authentication is encrypted. Multiple authentication methods are available, including Username and Password, Public Key (length and type can set as needed), Keyboard Interactive, and Kerberos.
How is reflection X used in a firewall?
Reflection X can be set to disallow all remote TCP/IP connections. This can be used to back up a misconfigured firewall or to provide primary defense in the event that no firewall exists. Host-based security can also be used in conjunction with SSH. Compression can be used to help in low bandwidth environments.
