6.1 Ensure the X Window system is not installed - Review

Information

The X Window system provides a Graphical User Interface (GUI) where users can have
multiple windows in which to run programs and various add on. The X Window system is
typically used on desktops where users login, but not on servers where users typically do
not login.

*Rationale*

Unless your organization specifically requires graphical login access via X Windows, remove it to reduce the potential attack surface.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Uninstall X Windows-# apt-get purge xserver-xorg-core*
