System Hardening: OS Level Defense

by Mohammad Latifi Sani

Overview

Operating systems are the last frontier before the system falls. Understanding how to harden them is a non-negotiable skill for cyber defenders, system administrators, ethical hackers, and red team professionals.

This book demystifies the core concepts of system hardening, including file system permissions, service attack surface reduction, secure boot configuration, password policy enforcement, patch management frameworks, Linux kernel security modules, and Windows hardening via Group Policy and registry lockdown.

Through a theory-first approach, Moe Sani teaches you how to think like an attacker so you can defend like a strategist.

*System Hardening: OS Level Defense* is more than a checklist — it's a mindset.

About the Author

Moe Sani — known in professional circles as Mohammad Latifi Sani — is a quiet force in the world of cybersecurity. With over 20 years of experience in ethical hacking, red teaming, and cyber warfare simulation, he has operated behind the scenes in some of the most sensitive digital environments in the world — rarely seen, but always one step ahead.

Starting his journey at age 15, Moe mastered the art of digital infiltration long before it became a mainstream skill. He’s held lead roles in critical infrastructure assessments, financial sector red teams, and high-stakes cyber threat hunting missions. His work spans advanced penetration testing, web exploitation, and AI-integrated security systems — often in silence, with impact echoing across entire organizations.

This book series is the first time Moe steps forward publicly to share his knowledge. Through Simple Cyber Sec, he's building a roadmap for serious learners — not just to use tools, but to understand the mindset behind every exploit and defense.

Moe is also the architect of AHOORAA, a next-gen AI engine powering multiple cyber intelligence platforms under the EcoNovaLabs umbrella. His passion lies in merging machine learning with ethical hacking, and preparing the next generation for a future where security is not just technical — it’s cognitive, predictive, and deeply human.
