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.

Building an Architecture – Scope and Requirements

In the previous chapter, we went through how to establish the laws of the universe, which set the context for our architectural design work. Specifically, we examined the nuances of the organization that have the potential to guide or constrain our designs or their subsequent execution. This includes the organization’s risk tolerances, goals, compliance requirements, context, business, and anything else that may play a role in the overall approach.

All these things are important to establish context and provide us with a framework to work within. However, on their own, they are not the entirety of what you need to know to plan and field a design. More is required to do that – in particular, gathering and putting together everything you need to know to lay out a full set of requirements systematically. This chapter is all about establishing those important boundaries: what our scope will be, how we can go about...
