Cybersecurity: A Practical Introduction

Cybersecurity is not just a matter of blocking malicious software: it also involves understanding how online anonymity works, how people are manipulated, and how defenses fit together across devices and networks. Cybersecurity: A Practical Introduction by Nihad A. Hassan and Rami Hijazi surveys those connected concerns, moving from core concepts to threats and practical defensive strategies.

From security fundamentals to real-world threats

The book begins with an introduction to cybersecurity, then turns to cyber anonymity and web layers and the foundations of cryptography. Its scope widens to cyber threats, advanced persistent threats (APTs), ransomware, and social engineering. Together, these subjects offer readers a way to consider both technical attacks and the human factors that can make systems vulnerable.

People, devices, and networks in the security picture

Later chapters explore open-source intelligence (OSINT), endpoint defense, and enterprise network defense. This progression spans individual devices and organizational infrastructure, while also considering how information gathered from public sources can matter to both defenders and attackers.

A broad introduction for curious practitioners

Written for working professionals, computing specialists, and IT enthusiasts, the book is presented as accessible to beginners as well as experienced practitioners. Readers looking to build familiarity with several major cybersecurity domains will find a wide-ranging introduction, from cryptographic foundations to network defense.

Explore the cybersecurity landscape

With its coverage of technical safeguards, evolving threats, and social engineering, this book provides a structured starting point for readers interested in how cybersecurity challenges connect—and how defense needs to account for both people and systems.
