Description

The Linux OS plays a foundational role in powering the servers that run the internet of today.- How do you make sure that a Linux deployment is secure?- How do you make sure that it does not contain miss-configurations that could allow a user to escalate privileges and become the administrator (root) user?This course covers the most useful techniques you need to know in order to enumerate a modern Linux OS deployment to find and exploit Privilege Escalation attack vectors.Consider these questions:- Are you interested in working in the security industry?- Do you want to learn how to test the security of a Linux OS deployment?- Do you like hands-on, practice-based learning?If you answered yes to these questions, then this course is for you.In this course I will show you how to test the security of a Linux OS deployment. For each technique covered, I have prepared custom exercises in the form of hands-on CTF challenges that will challenge your understanding and bring it to the next level.Feel free to check out the table of contents in order to understand the arguments covered.Thank you very much, and for any questions, critisim and feedback, you can always write to me.
