Linux Forensics for Beginners: Digital Investigation Basics

When a Linux server is compromised, security teams must act quickly to understand how the breach occurred and what data was accessed. This text-based course introduces you to the essential concepts of Linux digital forensics, preparing you to investigate security incidents on enterprise and cloud systems. By reading through detailed explanations, step-by-step commands, and practical scenarios, you will learn how to preserve digital evidence, analyze system logs, and reconstruct user activity. You will gain a solid understanding of how Linux stores data and how to extract valuable artifacts during an investigation. What you'll learn: - Understand the core principles of digital forensics and evidence preservation on Linux systems - Analyze system logs, including traditional syslog and modern systemd journald logs, to trace unauthorized activity - Examine user activity artifacts, bash histories, and login records to identify user actions - Investigate running processes, network connections, and open files during a live response scenario - Explore basic memory acquisition concepts and file system analysis techniques - Identify security anomalies in containerized environments and modern cloud deployments This written course begins with foundational concepts of Linux file systems and directory structures before moving into live response techniques, log analysis, and artifact recovery. You will progress from basic terminology to conducting structured digital investigations through realistic written walkthroughs. This course is designed for aspiring security analysts, system administrators, and cybersecurity beginners. No prior forensics experience is required, though a basic familiarity with the Linux command line is helpful.
