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.

Structures and documents

The dimensions described previously relate both to the goals of the organization (what is important to measure in how it achieves those goals) and also to how well a security measure works within the context of enterprise goals. This is what makes understanding the goals so important. But assuming that going through a full goal-mapping exercise to correlate every organizational goal to technology goals – and map, in turn, security goals to technology ones – represents a time investment that not every architect can afford to make, how can we get to a rapid understanding quickly so that our design work can proceed?

As we implied earlier, one way to do this is by looking at policy, procedure, standard, and guidance documentation that may already exist in the organization. This is because they are the codification of already-made decisions by the organization, which are, in turn, driven by the goals. Sometimes, these items are even referred to...
