Protip: systemctl disable: disable from launching at boot time. If you want to make sure a service cannot be started at all, what you want is systemctl mask.

e.g., if the (insecure) rsync daemon could be running at the moment, these three should have you covered:

sudo systemctl stop rsync
sudo systemctl disable rsync
sudo systemctl mask rsync

(PS. Yeah, you really shouldn’t be running the rsync daemon. And you don’t need it to use rsync over ssh.)
