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.

Understanding scope

“I think it’s important to get your scope at the right level of detail and, if possible, avoid scope creep as scope creep is the enemy of project management. Focus then at the beginning on developing the scope, validating the scope, and making sure everyone agrees to the scope. From there, you can get to a point where you can say the scope is frozen for a period of time while you execute. It’s a people skill involved with getting a scope that everyone can agree on and work to.”

– John Sherwood, Chief Architect, thought leader, and co-Founder of The SABSA Institute

If it sounds strange that we still need more data even to begin the process of design, consider an analogy to a physical building. A structural engineer might tell us that the tensile strength of a high-performance carbon steel beam is 550-670 N/mm2 (see Takumi Ishii et. al, Overview and Application of Steel Materials for High-Rise Buildings, JFE Technical Report...
