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.

If you’ve been following along, you’ll have a few things already prepared:

  • Informal scope: You’ve spent some time thinking about the scope of your planning, but you (purposefully) haven’t documented it yet. In Chapter 3, Building an Architecture – Scope and Requirements, we went through the process of defining an informal scope. In this chapter, we will build on that to arrive at an actual recordable design scope.
  • Existing landscape: In the last chapter (Chapter 4, Building an Architecture – Your Toolbox), we talked about strategies to understand what you have in place now. This ideally includes an understanding of existing constraints that you’ll need to account for and plan around (recall the gap analysis discussion), as well as an understanding of what is in place already so that you can look for areas of efficiency during the implementation process. Some projects will start with a blue ocean—meaning...
