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.

Before we dive into the meat of this chapter, the first thing we should note is that we have made the conscious decision to use terminology that will be most immediately transparent and accessible to everyone. This, however, will not always be the same terminology used by many of the security architecture frameworks, standards, and guidance that you may encounter.

For example, one of the most important concepts in this section is understanding the goals of the organization and mapping those goals to security outcomes and principles, as we stated previously. It is quite literally the case that any security effort, whether architecture, operations, incident response, or any other discipline within security, exists solely to help enable the organization to fulfill its mission. In the case of a for-profit entity, such as a company, this might mean being profitable or providing value to shareholders. In the case of a philanthropic organization, it might mean providing value...
