Dive into the physical and logical structure of Linux storage. The Linux Filesystem Hierarchy & Storage module breaks down where the OS stores its secrets, binaries, and configurations—and where attackers like to hide.

You will explore the Filesystem Hierarchy Standard (FHS), understand the deep mechanics of inodes, hard links, and symbolic links, and master advanced file discovery tools like find and stat. By the end of this module, you will know how to map the Linux filesystem, uncover hidden dot-files, and spot the world-writable directories that attackers exploit for privilege escalation.
