This comprehensive 3-in-1 course is a step by step guide that will help you to take control of your Linux servers and teach you hands-on techniques which will protect your server from internet attacks—from techniques that hackers use today in order to exploit your server, to hardening your server with some of the most advanced protocols out there. Prevent server exploits such as DDoS Protection, hardening login security protocols, and more! Perform a number of advanced Linux security techniques such as network service detection, user authentication, controlling special permissions, encrypting file systems, and much more!

Contents and Overview

This training program includes 3 complete courses, carefully chosen to give you the most comprehensive training possible.

The first course, Fundamentals of Linux, covers fundamentals of Linux in a step by step manner. This course explains and teaches all the important command-line tools and utilities, using very easy to understand, real-world examples to follow along with—in short, you'll learn everything you really need to know about Linux when starting out from scratch as a new system administrator or for any other reason.

The second course, Linux Server Security, covers securing your Linux server with the help of efficient tools and techniques. You will start by discovering techniques that professional hackers use in order to scan a website and a server, in order to carry out their intrusion attacks. Create secure accounts where we'll look into deleting and creating user accounts password and monitoring servers. Maintain your Linux Server in order to get optimized performance and stability. Moving ahead, you will focus on tools that can be used to enhance server security, understand the art of hardening passwords, and fix authentication failures.

By the end of the course, you will be confident enough to take control of your Linux servers and use hands-on techniques to protect your server from internet attacks.

The third course, Mastering Linux Security and Hardening, covers mastering the art of preventing your Linux system from getting compromised. This course has extensive coverage of techniques that will help prevent attackers from breaching your system, by building a much more secure Linux environment. Learn various security techniques such as SSH hardening, network service detection, and setting up firewalls, encrypting file systems, protecting user accounts, authentication processes, and so on. Moving forward, you will also develop hands-on skills with advanced Linux permissions, access control, special modes, and more. Lastly, this course will also cover best practices and troubleshooting techniques to get your work done efficiently. By the end of this course, you will be confident in delivering a system that will be much harder to compromise.

By the end of the course, you’ll secure your Linux server and protect it from intruders, malware attacks, and other external threats with the help of efficient tools and techniques.
