Are you interested in learning more about Linux Security? Then this is course for you! This course will teach you how to better secure a Linux system as well as understand how various Linux security controls work to increase security and meet compliance with various regulations. You will learn fundamentals of security such as users, permissions as well as more advanced topics like Selinux, auditing and PAM. You will also learn how to set up various services such as Rsyslog.

This course is a mix of lecture and demos to help you understand the concepts. To succeed in this course you should have a basic understanding of Linux System administration to include things like setting up networking, editing files and basic file management. This course focuses on Centos and Red Hat Linux, but some of the concepts would apply to other distributions as well. I would recommend you have access to a Centos or Red Hat system so you can follow along with some of the demos. Access can be provided by Amazon AWS and you can use the free tier if desired.

I am not affiliated in any way with either Red Hat or Centos.

Who is the target audience?
  • System Administrators working in an environment where Security is a concern
  • Auditors looking to learn more about Linux to better understand their auditing practice
  • Incident Responders wanting to understand the Linux Operating System better
  • Security Professionals who want to know how Linux implements security
  • If you are new to Linux, this course will not teach you the basics of Linux system administration. You would be better served taking some of the other courses on Udemy and then circling back to this course after a few weeks. You should have a good understanding of configuring a Linux system and getting around the command prompt before taking this course

IT Security Nerd

I am passionate about Information Technology. I am fascinated by the Information Security field as a whole. I have spent most of my time in security from a systems and security engineering background where I am hands on implementing individual solutions for customers to increase the security on their networks.

I have worked heavily with Unix and Linux administration. I have also worked with VMware Infrastructure. I have had other short development roles that make me a well rounded person such as Python and C# development and help me understand development better.

I teach part time as an adjunct professor. This role fits me because I love to teach information security to other people and spread my passion to other students.

I currently hold an M.S in Information Security and Assurance as well as certificates in CISSP, ITIL, Security+, CEH and ECSA.
