Ensure chrony is not run as the root user

MediumLevel 1Automatedlinux

Description

The file /etc/sysconfig/chronyd allows configuration of options for chrony to include the user chrony is run as. By default, this is set to the user chrony

How it is checked

Audit method: Shell command

shell
alt0() { command -v grep >/dev/null 2>&1 || { echo "step1: grep not installed"; return 1; }; o=$(bash -c 'grep -Psi -- '"'"'^\h*OPTIONS=\"?\h*([^#\n\r]+\h+)?-u\h+root\b'"'"' /etc/sysconfig/chronyd' 2>/dev/null); [ -z "$o" ] || { echo "step1: $o" | head -c 300; return 1; }; }; if alt0; then echo compliant; fi
Expected output
compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Edit the file /etc/sysconfig/chronyd and add or modify the following line to remove "-u root" from any OPTIONS= argument: Example: OPTIONS="-F 2" Run the following command to reload the chronyd.service configuration: # systemctl reload-or-restart chronyd.service
