One of the security tool has generated reports for our production system which is RedHat Linux 2.1 installed on it.

The error in question is :

unrestricted X server access (No X server access control )

Now when I tried to goole on above error found the following help.

"""""Restrict access to server: An open X display allows anyone, anywhere to view your screen, capture keystrokes and even execute commands remotely. This is a serious vulnerability that is easily fixed using xhosts or xauth. The xhost program is used to add and delete host names or user names to the list allowed to make connections to the X server, providing a rudimentary form of privacy control and security sufficient for a workstation environment (e.g. xhost +user@host when granting access).""""""""""

Now only thing I understood from above help is that I will have to restrict access to users using xauth or xhost. But how ??
If you have anything to say on this , would appreciate it

Start by entering these commands at the shell prompt:

man xauth
man xhost
Come back here if you have questions about those documents.

Hope this helps.
