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.

Considerations for Agile projects

“Recently, I’ve been doing more work with Agile and DevOps environments. One problem in how these models are used is that stories are often used to lay out requirements [for example, 'user stories']. In security, though, many of the architecture requirements stem from stories that are not ‘functional stories’ – instead, they might be invisible or taken for granted from a user point of view. This makes it harder to account for security in the design process, which, in turn, makes architecture even more important in these models.”

– John Tannahill, a Canadian management consultant specializing in information security

As we walked through the various phases of the waterfall architecture, you probably noticed that the stages in a waterfall development approach aren’t very iterative. As illustrated in the typical waterfall process shown in the previous section, there are stages of development...
