When you first create a new Ubuntu server, there are a few configuration steps that you should take early on as part of the basic setup.
- Buy a VPS with Ubuntu 20.04 LTS (or 18.04 LTS) (https://www.cloud.it/vps/vps-hosting.aspx).
- Update packages
$ apt-get update $ apt-get upgrade
Setup a Basic Firewall
- Check available UFW applications:
$ ufw app list
Output Available applications: OpenSSH
- Allow SSH connections:
$ ufw allow OpenSSH
- Enable UFW:
$ ufw enable
