Practical Cybersecurity Architecture

By: Ed Moyle, Diana Kelley

Overview of this book

Cybersecurity architects work with others to develop a comprehensive understanding of the business' requirements. They work with stakeholders to plan designs that are implementable, goal-based, and in keeping with the governance strategy of the organization. With this book, you'll explore the fundamentals of cybersecurity architecture: addressing and mitigating risks, designing secure solutions, and communicating with others about security designs. The book outlines strategies that will help you work with execution teams to make your vision a concrete reality, along with covering ways to keep designs relevant over time through ongoing monitoring, maintenance, and continuous improvement. As you progress, you'll also learn about recognized frameworks for building robust designs as well as strategies that you can adopt to create your own designs. By the end of this book, you will have the skills you need to be able to architect solutions with robust security components for your organization, whether they are infrastructure solutions, application solutions, or others.

Chapter 3: Building an Architecture – Scope and Requirements

In the last chapter, we went through how to establish the "laws of the universe" that establish context for our architecture 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, but as you might imagine, they are not the entirety of what you need to know to actually plan and field a design. In fact, it's not even everything you need to know to lay out a full set of requirements or specifications in a systematic way.

In this chapter, we'll look at the following topics:

  • Understanding scope
  • Setting architectural scope
  • Scope – enterprise security
  • Scope –...
