CYBERSECURITY JOB HUNTING GUIDE
Red Hat Enterprise Linux
Author: Stefan Waldvogel
RHEL, the professional Linux for servers
Do you look for valuable Linux skills?
Do you look for a well-paid job?
Why not switching your primary system to Red Hat Enterprise Linux (RHEL)?
What is so special about this Linux?
Two reasons: Until a year ago, it was impossible to get this Linux for free, and the biggest companies in the world use this Linux for their servers.
Why does it matter?
If you go into an interview and use this system on a daily base, you stand out. The reason is, not many people have this knowledge, and bigger companies look for such people. If you use this system as the main system, you can write on your resume: "proficient in RHEL". This small sentence opens you a lot of other doors. In the US, we have about 5,000 open positions with this requirement. Compared to the 62,000 available jobs in Cybersecurity (April 2021), it does not look a lot, but it adds ~10% more jobs with a single skill, and you stand out without doing much. If you use it as the main system, it does not mean you can do all the jobs, but it is one small and free extra "brick".
How do you get it?
Since June 2020, everyone can join Red Hat Developer program, and you can download it for free here: developers.redhat.com/topics/linux
Other options are cloud-based machines. In Azure or AWS, you can pick RHEL and test it for free.
How to install it?
Download the iso and burn a USB stick or spin up a VM.
Other things to know:
RHEL is a hardened and very stable OS. If you install it, you do not see a lot of tools. You get a terminal and some programs. Install everything that you need.
RHEL is Fedora-based, and you learn a lot of new commands. Kali or Ubuntu is Debian-based, and the commands are different.
Let us say you want to install Brave (it is a secure browser), it looks like this:
sudo dnf install dnf-plugins-core
sudo dnf config-manager --add-repo https://brave-browser-rpm-release.s3.brave.com/x86_64/
sudo rpm --import https://brave-browser-rpm-release.s3.brave.com/brave-core.asc
sudo dnf install brave-browser --> on Kali/Ubuntu, it would look like: sudo apt install brave-browser
