GEN005220 - .Xauthority or X*.hosts (or equivalent) file(s) must be used to restrict access to the X server.

Information

If access to the X server is not restricted, a user's X session may be compromised.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Create an X*.hosts file, where '*' is a display number used to limit X window connections. Add the list of authorized X clients to the file.
