Types of Linux-based firewalls

- Let's talk about the different types of firewalls you can install into your Linux server. First is UFW. This is the Uncomplicated Firewall. It's developed by Canonical, and they are the makers of the Ubuntu distro for Linux. It's easy to use, but it has some limited security, so you need to watch for that. The next one is firewalld. This is a fairly comprehensive firewall developed by Red Hat and designed for workstations and servers, though it can work for entire networks as well. And it's a front-end utility for nftables. And that brings us to nftables. That's today's sophisticated backend firewall. The older version was iptables. But today, it's a good idea to use nftables whenever possible. This works directly with the Linux kernel and it utilizes the nft front-end tool or userspace tool. It's designed for networks and servers. If you want true firewalling, go with nftables and nft, and we're going to be showing labs and demonstrating how these work for each of these firewalls…
