Part 1:Foundations

Cybersecurity architecture requires a fusion of strategic perspective and technical detail. Before exploring the specifics of implementation, establishing core foundations proves essential.

This opening part of the book focuses on orienting you with fundamental concepts, principles, and domains underpinning effective cybersecurity architecture. Chapter 1 provides an accessible overview of key cybersecurity basics, positioning why security matters across increasingly interconnected technology landscapes.

Chapter 2 delves deeper into foundational areas including access controls, network security, cryptography, and risk management. Practical examples illustrate how each contributes to multilayered protection.

With core building blocks in place, Chapter 3 delineates what distinguishes the cybersecurity architect role and its responsibilities. It explores the synergies and trade-offs between security strategies and business objectives that architects must balance.

Together, these chapters equip you with baseline security knowledge and clarify the architect’s role. By grounding discussions in principles and context, the foundations prepare you to explore pathways to grow architectures strategically in alignment with organizational needs. Even those already familiar will benefit from the concise refresher this part provides on the essential concepts underpinning the latest frameworks, controls, and best practices.

This part has the following chapters:

• Chapter 1, Introduction to Cybersecurity
• Chapter 2, Cybersecurity Foundation
• Chapter 3, What Is a Cybersecurity Architect and What Are Their Responsibilities?
