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.

Introduction to the architect’s toolbox

Architects in the physical world don’t just have an idea, grab a hammer, and immediately start building. This is for good reason. To do so would fail to account for a large number of valuable intermediate steps that are necessary to ensure the validity of the final product. Missing, eliding, or otherwise deprioritizing these steps violates the generally accepted practices of the profession and would almost certainly result in an edifice that is suboptimal, unsafe, or unfit for purpose.

Security architecture is no different in this respect. There are a number of key steps involved in the development of a security architecture. Each of these steps can be thought of as a specialized tool to validate the end-state design in a very particular and discrete way. Obviously, not every tool will be applicable to every situation. However, building an understanding of what tools there are means that you can select the right one for your...
