Join Shawn Powers as he teaches you how to configure system logging and set up software firewalls by using multiple configuration tools.

Gain an understanding of the network connection and flow that takes place between hosts; how stateful and stateless firewalls block or allow traffic based on rules; and how the Linux system uses Netfilter, IPTables, UFW, and Firewalld for packet filtering. Learn how to open and close service ports on Ubuntu and CentOS, how to configure a Linux system to function as a NAT router, and how to define the services and ports used to manage a Linux system.

This skill is part of a series that will prepare you for CompTIA's XK0-004 exam, the one exam that must be passed to receive the Linux+ certification.
