If you need to change these settings after bootstrapping, you can run `./discourse-setup` again (it will re-use your previous values from the file) or edit `/containers/app.yml` manually with `nano` and then `./launcher rebuild app`, otherwise your changes will not take effect.

- We strongly suggest you turn on automatic security updates for your OS. In Ubuntu use the `dpkg-reconfigure -plow unattended-upgrades` command. In CentOS/RHEL, use the [`yum-cron`](https://www.redhat.com/sysadmin/using-yum-cron) package.
- If you are using a password and not a SSH key, be sure to enforce a strong root password. In Ubuntu use the `apt install libpam-cracklib` package. We also recommend `fail2ban` which blocks any IP addresses for 10 minutes that attempt more than 3 password retries.
