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.

Case study – data gathering

“One of the most powerful tools we have is the ability to collect and analyze data. Nearly every organization collects metrics: in many cases, too much. They collect metrics for system performance, system health, and numerous other areas. But not, very often, do they collect the right information. In fact, I have almost never seen an organization collecting and using the right set of metrics. The ones that get closest have a definitive edge.”

– Deepayan Chanda, Principal (Cybersecurity Strategy, Architecture, and Governance), UNSW (University of New South Wales)

In an interview, we asked Deepayan Chanda about how important data collection tools and telemetry are to the architecture process. He explained both their importance as well as how he’s seen organizations get it right (and wrong):

“Most commonly, I see metrics that are defined and curated in a way that suits the person presenting. As an example,...
