Miguel Angel Contreras (LHE)

“Recommended for all Linux users who want to improve their offensive security skills and hardening techniques on Linux systems. The course has well-structured and comprehensive material for all the labs, with every topic focused on the Linux userland. If you are a Linux sysadmin, you should be fine taking this course—just try harder. For people who already work in Linux security, you will learn new things depending on your experience, and you should be able to complete it faster.”
