The Linux for InfoSec Professionals course is a “Zero to Hero” style of training program designed to take someone with little to no Linux experience up to a highly competent Linux practitioner. It will not only teach you the security concepts and guidelines that will keep your Linux servers safe, it will walk you through hardening measures step-by-step.

This course also serves as a great prep guide for the Comptia Linux+ certification.

The CompTIA Linux+ certification covers common tasks in major distributions of Linux, including the Linux command line, basic maintenance, installing and configuring workstations, and networking. Linux+ is comprised of two exams – LX0-103 and LX0-104. Candidates must pass LX0-103 before taking LX0-104.

Unlike Security+ and Network+, you never have to renew the Linux+ certification. This accreditation is good for life. There are no Continuing Education (CE) requirements.
