Description

This four-hour, hands-on course is a quick start into the world of Linux.

Why are all the “cool kids” using Linux? Could it be that the best tools for both the Red and Blue teams run on Linux? Could it be because modern, cloud-based infrastructures are built on Linux and easily managed using Linux-based tools? Or that free Linux operating systems make it easy to build out your own home lab environment?

Don’t fear the Linux command-line. Embrace it! Learn how to get around in Linux with simple command line tricks and short-cuts to improve your efficiency. Understand the Linux philosophy and the basic building blocks that will have you up and going in no time. And know how to get help from the operating system so that you can continue to learn and grow on your own.
