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.

Architecture – The Core of Solution Building

In the first chapter of this book, we went through what a cybersecurity architect is, what they do (that is, the functions they perform), and the value they – and the architecture process itself – can provide to an organization. In this chapter, we will build on that to begin the process of describing how to develop an architecture.

Throughout this chapter, we will explore the structures that organizations set up to ensure key outcomes are achieved. The architect needs to understand these elements because the whole point of architecture is to support the organizational mission – to do that, we have to understand what that mission is and the strategies that the organization has put in place to achieve it. This will be the backdrop to all the work we do as security architects.

We’ll walk through how organizations derive their goals (including security goals), and strategies they will use to ensure those...
