- [Sean] Hi, I'm Sean Colins and this is Linux: Firewalls and SELinux. In this course, we will cover two similar concepts in Linux server and workstation security that have very different effects on your system. We start the course with firewall basics and progress through to show you how firewalld can be configured to allow communication on network ports associated with various services. We then move on to the concepts of SELinux, or Security-Enhanced Linux, showing you how SELinux works, discussing many of the fundamental concepts employed and working directly with many of the commands and methods used by SELinux that you, as a systems administrator, need to know to get started exploring Fedora 25 Linux server and workstation firewalls and SELinux.
