By removing the following packages, the system no longer has X Windows installed.

xorg-x11-server-Xorg xorg-x11-server-common xorg-x11-server-utils

If X Windows is not installed then the system cannot boot into graphical user mode. This prevents the system from being accidentally or maliciously booted into a graphical.target mode. To do so, run the following command:

sudo yum remove xorg-x11-server-Xorg xorg-x11-server-common xorg-x11-server-utils


Unnecessary service packages must not be installed to decrease the attack surface of the system. X windows has a long history of security vulnerabilities and should not be installed unless approved and documented.


Shell script

The following script can be run on the host to remediate the issue.


# remove packages
if rpm -q --quiet "xorg-x11-server-Xorg" ; then

    yum remove -y "xorg-x11-server-Xorg"

if rpm -q --quiet "xorg-x11-server-utils" ; then

    yum remove -y "xorg-x11-server-utils"

if rpm -q --quiet "xorg-x11-server-common" ; then

    yum remove -y "xorg-x11-server-common"


Ansible playbook

The following playbook can be run with Ansible to remediate the issue.

- name: Ensure xorg packages are removed

The installation and use of a Graphical User Interface (GUI) increases your attack vector and decreases your overall security posture. Removing the package xorg-x11-server-common package will remove the graphical target which might bring your system to an inconsistent state requiring additional configuration to access the system again. The rule xwindows_runlevel_target can be used to configure the system to boot into the multi-user.target. If a GUI is an operational requirement, a tailored profile that removes this rule should be used before continuing installation.
