Ready to move beyond basic commands and truly understand how Linux systems are secured—or, more importantly, how they fail? The LabEx Linux learning path is designed specifically for beginners who want practical, hands-on experience. Forget passive video tutorials. We put you directly into an interactive shell playground where you learn by doing.
This path gives you a clear roadmap for mastering Linux administration, system management, and shell scripting. But today, we’re focusing on a critical skill: security auditing. We’ve hand-picked five beginner labs that teach you how to identify and exploit common service misconfigurations. Let’s dive in and see what you’ll build!
Rsync Enumeration and Anonymous Sync
Difficulty: Beginner | Time: 20 minutes
In this challenge, you'll act as a security analyst to investigate a misconfigured backup server. You will use nmap to identify an anonymous Rsync service, synchronize files from a public share, and retrieve a hidden flag to expose the data leak.

Rsync Enumeration and Anonymous Sync
Difficulty: Beginner | Time: 20 minutes
In this lab, you will learn to enumerate and exploit a misconfigured Rsync service. You'll use nmap to detect the service, connect anonymously to sync files from a remote target, and retrieve a flag, highlighting risks in backup synchronization services.

Hashcat Installation and System Benchmark
Difficulty: Beginner | Time: 25 minutes
In this lab, you will learn how to install Hashcat, the popular password recovery tool, on a Linux system. You will also perform a system benchmark to measure its performance.

SMB Enumeration and Guest Access
Difficulty: Beginner | Time: 20 minutes
In this lab, you will learn to perform Server Message Block (SMB) enumeration. You'll use nmap to identify the SMB service, exploit a guest access misconfiguration with smbclient, and retrieve a flag from a shared directory, simulating a common network vulnerability.

SSH Enumeration and Key-Based Access
Difficulty: Beginner | Time: 20 minutes
In this lab, you will learn to enumerate an SSH service using nmap, exploit a weak key-based authentication misconfiguration to gain shell access, and retrieve a flag. This exercise focuses on SSH security best practices.
