Ensure HTTP server is not enabled

MediumLevel 1Automatedros

Description

HTTP or web servers provide the ability to host web site content. The audit requires the HTTP server unit(s) apache2 not to be enabled or active (systemctl). Host-level control from the CIS ROS Melodic benchmark (Ubuntu 18.04 robot hosts); run as root.

How it is checked

Audit method: Shell command

shell

command -v systemctl >/dev/null 2>&1 || exit 1
bad=0
for u in apache2; do
  s=$(systemctl is-enabled "$u" 2>/dev/null)
  case "$s" in enabled|enabled-runtime|alias|indirect) echo "$u is $s"; bad=1 ;; esac
  systemctl is-active --quiet "$u" 2>/dev/null && { echo "$u is active"; bad=1; }
done
[ "$bad" -eq 0 ] && echo compliant

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Run the following command to disable apache: # systemctl --now disable apache2
