    FAQs

    What will you learn in this Linux security training?

    This course will show you all the ways that a Linux operating system's security is radically different from the corporate ones like macOS and Windows. This course covers authentication methods, logging and backup, firewall configurations and permission management – everything a Linux administrator needs to keep the network safe.

    Who should take this Linux security course?

    This isn't a simple course and it's not a primer on networking principles, so this course isn't great for brand new admins. Some of the security configurations it covers are routine, but it also goes into advanced detail – that's why systems engineers and network engineers are the best audience.

    Is this training in Linux security associated with any certifications?

    Yes, when this course on Linux security was developed, it was with the Linux+ certifying exam from CompTIA in mind. The material on this course will help learners take the XK0-005, but only the security-related portions. Other exams that include network security will also be easier after this course.

    What certification should you consider after taking this course in Linux security?

    If you take this course and decide that Linux administration and configuration is right for your job, the Linux+ certification from CompTIA is your best bet. This course was designed to cover only the security portions of that exam, but there are other courses for the rest of the exam.

    Why should you take this Linux security training?

    You should take this Linux security training for the practice and first-hand experience alone. The video training is excellent and the visualizations of network operations are helpful, but the key to being a good network security professional on a Linux network is practice – and you'll get a lot.

    Who is this for?

    This Linux Security training is considered engineer-level Linux training, which means it was designed for systems engineers. This security skills course is designed for systems engineers with three to five years of experience with open-source platforms.

    What our learners say

    • Very easy and fun way to learn. Keith Barker is my favorite, he'll throw in jokes here and there and it makes me remember certain study points. I highly recommend this app and purchasing subscriptions, it is truly worth the money.

    • Practice exams help you have an overview of your readiness. If you have failed a couple questions in one area, you can go back and work on them.
