Security of e-Systems and Computer Networks by Mohammad Obaidat – A Comprehensive Textbook on Network Security and Crypt

Introduction

In an era where digital transactions, wireless communication, and online services form the backbone of modern society, the security of e-systems has become a non-negotiable priority. From e-commerce platforms to healthcare networks and government portals, the need to protect sensitive data and ensure seamless operations is paramount. Security of e-Systems and Computer Networks by Mohammad Obaidat offers a comprehensive and technically rigorous exploration of the principles, tools, and applications that safeguard today's interconnected world. Published by Cambridge University Press, this hardbound volume is an essential reference for students, researchers, and professionals in India and beyond.

Book Overview

This book systematically addresses the core pillars of e-security: user authentication, system integrity, confidentiality of communication, availability of business services, and non-repudiation of transactions. It bridges theoretical foundations with real-world implementation, making it a practical guide for understanding how to design and manage secure e-systems. The author covers critical areas such as public key infrastructure (PKI), biometric authentication, trust management, intrusion detection, virtual private networks (VPNs), malware analysis, and risk management. Each chapter is enriched with examples and case studies that reflect current industry practices.

Key Highlights

• Comprehensive coverage of e-security fundamentals and advanced topics in a single volume.
• Practical orientation with numerous examples and scenarios relevant to Indian and global contexts.
• Focus on emerging technologies like biometric systems, PKI, and trust management frameworks.
• Detailed discussion on intrusion detection, VPNs, and malware countermeasures.
• Rigorous yet accessible writing style suitable for both classroom learning and self-study.

Inside the Book

The book is structured to guide readers from basic concepts to complex security architectures. Early chapters introduce the fundamental threats and vulnerabilities in e-systems, followed by in-depth explorations of cryptographic techniques, authentication protocols, and network security mechanisms.
