To do this, open the UFW configuration file in your preferred text editor. If your Virtual Private Server (VPS) is configured for IPv6, ensure that UFW is configured to support IPv6 so that it configures both your IPv4 and IPv6 firewall rules. Both of these initial server setup guides will ensure that you have UFW installed on your machine and that you have a secure environment you can use to practice creating firewall rules. To set this up for Debian, follow our guide on Initial Server Setup with Debian 11. To set this up for Ubuntu, follow our guide on Initial Server Setup with Ubuntu 20.04. Your server should have a non- root user with sudo privileges. To follow this tutorial, you will need a server that’s running either Ubuntu or Debian. You’ll also learn how to set up UFW default rules to allow or deny connections for ports and IP addresses, delete rules you’ve created, disable and enable UFW, and reset everything back to default settings if you prefer. In this tutorial, you’ll set up a firewall using UFW to secure an Ubuntu or Debian cloud server. UFW is well-supported in the Linux community, and is typically installed by default on many distributions. UFW is a front-end to iptables that aims to provide a more user-friendly interface than other firewall management utilities. Many of these utilities (e.g., iptables) have a lot of functionality built into them, but do require extra effort from the user to learn and understand them.Īnother option is UFW, or Uncomplicated Firewall. Su dev & ssh-keygen -t rsa -b 4096 -C /var/Previously, setting up a firewall was done through complicated or arcane utilities.

I would like to ask you if there are any security issues in my workflow or how can I improve the security of the system. I read a lot of guides and I wrote down all the steps those I did. It also need to offer SFTP and GIT support. This is the first time I had to configure an Unix Server as a remote server for a website based on LAMP.
