Practical Cybersecurity Architecture - Second Edition

By: Diana Kelley, Ed Moyle

Overview of this book

Cybersecurity architecture is the discipline of systematically ensuring that an organization is resilient against cybersecurity threats. Cybersecurity architects work in tandem with stakeholders to create a vision for security in the organization and create designs that are implementable, goal-based, and aligned with the organization’s governance strategy. Within this book, you'll learn the fundamentals of cybersecurity architecture as a practical discipline. These fundamentals are evergreen approaches that, once mastered, can be applied and adapted to new and emerging technologies like artificial intelligence and machine learning. You’ll learn how to address and mitigate risks, design secure solutions in a purposeful and repeatable way, communicate with others about security designs, and bring designs to fruition. This new edition outlines strategies to help you work with execution teams to make your vision a reality, along with ways of keeping designs relevant over time. As you progress, you'll also learn about well-known frameworks for building robust designs and strategies that you can adopt to create your own designs. By the end of this book, you’ll have the foundational skills required to build infrastructure, cloud, AI, and application solutions for today and well into the future with robust security components for your organization.

Part 1: Security Architecture
Part 2: Building an Architecture
Part 3: Execution


Throughout this chapter, we’ve built on the techniques that we’ve teed up in prior chapters and extended them to the application space. We positioned the key tasks through the lens of a process-based systems security engineering methodology (or at least the architectural elements of that discipline), rather than a purely enterprise architectural one. This lets us work within the constraints of the SDLC that our organization uses.

From here, we will start executing our architectural vision. Whether you created a vision at the enterprise scope in the previous chapter or created one at the application scope in this chapter, the next step is to lay the groundwork to put it into practice. This includes engaging subject matter specialists and engineers in key supporting areas and mapping out a technical architecture to support the higher-level, business-focused ones. We will do this in the next chapter.
