Linux Fundamentals

Master the core Linux skills required for SOC Analysts, Security Engineers, and Cloud Professionals through fully hands-on labs.

Self-Paced by Rajneesh Gupta

Overview

This project introduces you to Linux from the ground up. You will learn how the operating system works internally, navigate the filesystem, manage users and permissions, and monitor processes using real-world commands.
Each topic is followed by practical exercises to prepare you for security operations, log analysis, and cloud workloads — where Linux powers 80–90% of servers globally.

By the end of this project, you’ll confidently operate Linux systems just like cybersecurity professionals do in enterprise SOC environments.

What You'll Learn

  • Linux OS & Kernel Fundamentals

    Understand what Linux really is — the kernel vs operating system — and how it manages processes, memory, system calls, and hardware resources.

  • Filesystem & Directory Breakdown

    Explore the Linux filesystem structure including critical paths such as /etc, /var/log, /home, /bin, and /tmp. Learn how logs, configurations, and system binaries are organized.

  • Hands-on File & Directory Operations

    Create, edit, move, and delete files using command-line tools. Practice file viewing utilities like cat, less, head, and tail -f — essential for log analysis.

  • User Management & Permission Security

    Manage users and groups, understand UID/GID, and configure secure access using sudo, chmod, and chown — core skills for privilege control and threat investigations.
