This page highlights a series of Linux-based cybersecurity labs completed for CYSE 301: Cybersecurity Techniques and Operations. These hands-on projects involved practicing system hardening, incident response, ethical hacking, and securing operating systems against common cyber threats. Each lab focused on applying operational security concepts in real-world scenarios to strengthen technical skills and critical thinking.

Module 0 – Basic Linux Commands

This lab focused on practicing essential Linux terminal commands used for file navigation, permissions, user management, and basic system control in cybersecurity environments.
