Requirements: .ePUB, .PDF reader, 10 MB
Overview: Whether you’re a student stepping into the world of cybersecurity or a self-taught learner eager to build real-world skills, this book is your gateway to understanding and mastering Linux from both offensive and defensive perspectives. Designed for readers with a basic familiarity with Linux, it dives deep into the practical techniques that form the backbone of system security. Through more than 100 hands-on exercises, you’ll explore how attackers exploit Linux systems―and how defenders can harden them. Learn to navigate Bash with precision, manage users and authentication, crack password hashes, and uncover hidden processes. You’ll gain insight into Systemd’s role in service management and persistence, and develop the skills to configure powerful security frameworks like SELinux and AppArmor. This book doesn’t just teach theory―it builds capability. You’ll learn how Linux handles file permissions and access control, how software is installed and verified, and how to think like both an attacker and a defender. Each chapter is packed with actionable knowledge that prepares you for real-world scenarios and professional challenges. This book begins with an introduction to Bash – how it starts, how it is configured, how it can be used by attackers, and how Bash commands can be recorded and logged for defenders. It continues with the fundamentals of local Linux users and groups, with explanations of how users are added, removed, and managed. Password authentication and pluggable authentication modules (PAM) are described; the reader learns how password hashes are created, stored, and cracked with John the Ripper. Ideal for students in Computer Science, early-career professionals, and career changers aiming to break into cybersecurity. Whether used as a textbook or a self-study guide, this book equips readers with the hands-on experience needed to thrive in the field.
