Course Description
Why Linux Security Matters
Linux powers modern infrastructure, cloud platforms, containers, and enterprise applications. Whether you're a Linux administrator, DevOps engineer, SRE, or IT professional, understanding how to secure Linux systems is a critical skill in today's environments.
In this course, you'll learn practical Linux security concepts and gain hands-on experience with the tools commonly used to assess, monitor, harden, and troubleshoot Linux systems.
We'll begin with the fundamentals of Linux security, including defense in depth, least privilege, detection and monitoring, and a practical security assessment workflow. These concepts will help you understand not only how security tools work, but when and why to use them.
From there, we'll use real-world demonstrations to assess, monitor, harden, and troubleshoot Linux systems using industry-standard security tools.
