Bandit Level 01

Learning Objective

Develop familiarity with navigating the Linux filesystem and locating readable files within directories.

---

Background

Linux systems organize information using a hierarchical directory structure. Understanding how to move between directories and inspect files is a foundational skill for system administration and cybersecurity.

This level reinforces how users interact with files from the terminal and how information is retrieved from the filesystem.

---

Key Concepts

• Terminal interaction
• Files vs directories
• Relative vs absolute paths
• Reading file contents

---

Tools & Commands (For Study)

• ls — list directory contents
• cd — change directories
• cat — display file contents
• pwd — print working directory

---

Why This Matters in Cybersecurity

Security professionals often analyze configuration files, logs, and system artifacts stored throughout a filesystem. The ability to confidently navigate directories and inspect files is critical in tasks such as:

• Log analysis
• Incident response
• Privilege escalation research
• Configuration auditing

Reflection Questions

• Why is understanding directory structure important in Linux systems?
• How could improper file permissions expose sensitive data?
• What risks might occur if users misunderstand file paths?
