Ensure rsync service is not enabled

MediumLevel 1Automatedcos

Description

The rsyncd service can be used to synchronize files between systems over network links. The rsyncd service presents a security risk as it uses unencrypted protocols for communication.

How it is checked

Audit method: Shell command

shell
alt0() { command -v systemctl >/dev/null 2>&1 || { echo "step1: systemctl not installed"; return 1; }; o=$(bash -c 'systemctl is-enabled rsyncd' 2>&1); printf '%s\n' "$o" | tr -s ' \t' '  ' | sed 's/^ //;s/ $//' | grep -Fxq -- disabled || { echo step1: missing disabled; return 1; }; }; if alt0; then echo compliant; fi
Expected output
compliant

How it is fixed

Fix method: Guidance or infrastructure patch

Run the following command to disable rsyncd : # systemctl --now disable rsyncd /etc is stateless on Container-Optimized OS. Therefore, the steps mentioned above needs to be performed after every boot.
