About the course

In this non-technical course, we will cover some of the most important concepts to understand when it comes to server security.

While this course has a focus on Red Hat and CentOS servers, many of the concepts and suggestions can be used by anyone who has a Linux server, regardless of the provider. Indeed, many of the lessons in this course cover items that are available on all Linux and many Unix systems.

In this course we will cover many areas to give you an idea of what you, or your IT department, should be focusing on. We won’t be going in-depth in detail or showing you how to perform the tasks beyond an introductory level.

In the last section of this course, we will provide suggestions for further study if you want to expand on your technical knowledge.
