Ensure xinetd is not installed

MediumLevel 1Automatedros

Description

The eXtended InterNET Daemon (xinetd) is an open source super daemon that replaced the original inetd daemon. The xinetd daemon listens for well known services and dispatches the appropriate daemon to properly respond to service requests. The audit requires xinetd not to be installed. 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 dpkg-query >/dev/null 2>&1 || exit 1
bad=0
for p in xinetd; do
  s=$(dpkg-query -W -f='${Status}' "$p" 2>/dev/null)
  case "$s" in *' installed') echo "$p is installed"; bad=1 ;; esac
done
[ "$bad" -eq 0 ] && echo compliant

Expected output: compliant

How it is fixed

Fix method: Guidance or infrastructure patch
