Linux File System Hierarchy Explained (SOC Analyst Perspective)
When you step into the world of cybersecurity — especially into a Security Operations Center (SOC) — your relationship with an operating system changes completely. You no longer see Linux as “just an OS”. You start seeing it as a crime scene, where every directory can contain evidence, every file can tell a story, and every log can confirm or deny an attack.
One of the most important foundations for any SOC analyst is a clear and deep understanding of the Linux File System Hierarchy. Without this, log analysis, incident response, threat hunting, and even SIEM investigations become guesswork.
This article explains the Linux File System Hierarchy from a SOC Analyst’s perspective, not just what directories exist, but why they matter in real-world investigations.
