Information Security Fundamentals – Paperback

Description

Would you build a house on sand?

Most organizations invest heavily in security tools, frameworks, and compliance programs — yet remain dangerously exposed. The reason is rarely the technology. It is the foundation beneath it. Practitioners who lack a deep, structured understanding of how information security’s building blocks interconnect will always produce solutions that are fragile, incomplete, and reactive.

Mastering Information Security — Volume 1: Information Security Fundamentals was written to change that.

This 600-page definitive reference is the first volume in the Mastering Information Security series — a comprehensive body of knowledge designed to take security practitioners from technical execution to strategic leadership. Built not around individual tools or certifications, but around the interconnected architecture of knowledge that separates true security professionals from technicians.

What you will master in Volume 1:

The core pillars and principles of information security — including the CIA triad, defence in depth, least privilege, need to know, and zero trust — and how they govern every security decision you will ever make in practice.

All 25 security domains organized across three coherent tiers: Strategic Management covers governance, risk management, compliance, GRC, personnel security, and business continuity. Security Engineering covers network security, application security, cloud security, identity and access management, data security, cryptography, endpoint security, and physical security. Security Operations covers threat intelligence, vulnerability management, incident response, security monitoring, and penetration testing.

The full ecosystem of frameworks, standards, and guidance — ISO 27001, NIST CSF, CIS Controls, COBIT, SOC 2, and more — applied in a way that genuinely strengthens security posture, not just satisfies auditors.

A complete ISMS implementation model with 4 stages and 20 steps, brought to life through three detailed real-world case studies: NovaPay Financial Services, HealthBridge Hospital, and GlobalTrust Financial Services — each presenting a different organizational context, risk profile, and implementation challenge.

Critical thinking scenarios and 40 MCQs per chapter designed to sharpen your analytical judgment and prepare you for real-world security leadership decisions.

This book is for you if:

You are a security practitioner ready to move from technical execution to strategic leadership. You are an aspiring or current CISO who needs a structured command of the entire security landscape before stepping into the role. You are a security architect, consultant, or analyst who wants to build solutions that are coherent, resilient, and built to last. You are a student or professional preparing for certifications including CISSP, CISM, ISO 27001 Lead Implementer, or CISA — and want the deep understanding that goes beyond exam prep.

Why this series exists:

The Mastering Information Security series was created because the field needed a structured, practitioner-grade body of knowledge — not another certification guide, not another tool manual, and not another collection of blog posts dressed up as a book. Each volume builds on the last, creating a complete and coherent command of information security from foundations through to advanced specialization.

Volume 1 is your starting point. Your foundation. The book you will return to throughout your career.

Information security built without deep fundamentals is a house on sand. This book is your foundation.
