This video comes from our Linux System Hardening course. The workshop itself goes into a lot of useful detail for professionals working with corporate systems and networks that help you protect Linux in line with the field's best practices. This little thing, however, is just aimed to help you get started with a simple firewall - so it's really useful to anyone wanting to protect their Linux (you could argue it's useful to everyone, period ;)). With this video you'll get going with ufw in seconds, learn about profiles, creating your own custom firewall rules, and setting up logging. Dive in!
