Practical Cybersecurity Architecture

Chapter 1: What is Cybersecurity Architecture?

Let's face it, cybersecurity can be a scary, stress-inducing proposition. And it's no wonder. Cybersecurity in modern business is high stakes. We've all seen headlines about data breaches, attacks, even accidental exposures impacting some of the largest companies (not to mention governments) in the world. The truth is, if you do security wrong, you open yourself up to attack. In fact, even if you do everything perfectly, circumstances can still put you at risk anyway. It's a challenging field – and it can be difficult to get right.

We want to be clear right from the start that this book is not about a new security architecture framework, a new set of competing architectural methods to what already exists, and it's not a reference book. These all already exist and provide plenty of value to those actively using them. In fact, we might argue that the single biggest limiting factor to the discipline itself...

Understanding the need for cybersecurity

"I think it's useful to recognize that different stakeholders have different viewpoints. As an example, imagine you are standing on a hill: in front of you there is a valley and mountains to the east and west. Multiple people in that same setting will have a different viewpoint depending on where they are standing and the direction they look. This is similar to enterprise architecture: different disciplines, users, and stakeholders have a different view depending on their focus. The security architect needs to be able to see all these views at the same time. This is because security is a cross-cutting architectural concept that can't be singled out and put into its own, separate box. Instead, it needs to cut across the whole organization and take these different viewpoints into account."

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

There are numerous unknowns involved...

What is cybersecurity architecture?

"Cybersecurity architecture is a fusion of architecture and cybersecurity. "Cybersecurity" is a combination of "cyber" (from the Greek word κυβερνήτης meaning "helmsman") and security ("the freedom from risk or danger"). Putting these all together, it's a model to produce an intended outcome related to freedom from technology-related danger."

– Dan Blum, Cybersecurity Strategist, Security Architect, and author of the book Rational Cybersecurity for Business

The easiest way to understand cybersecurity architecture is through a comparison with the role of an architect in the physical world, such as one who is working on a large structure such as a bridge, tunnel, skyscraper, museum, or a new house.

In the physical world, it's easy to understand what an architect does. We all know that you can't just forego...

Architecture, security standards, and frameworks

Knowing then what the purpose of the architect is and where/how they might be involved, it's important to spend some time talking about the process that they employ to get there. In beginning this discussion, it's important to recognize that much of that process will be unique and adapted to the organization employing it. We've seen that the goals of the security architect, what they're responsible for, and the role that they play within a given organization can vary depending on a few different factors: the organization itself, the scope and focus of the architect's role, and so on. These same factors will play a role in the process that the architect will follow to realize the results the organization needs.

Secondly, we've purposefully refrained from discussing much about the mechanics of how the architect approaches these tasks. We'll get there – but for now, we want to make sure that...

Architecture roles and processes

"If your only tool is a hammer, every problem looks like a nail. Meaning, if you talk to a developer or someone who is a product security manager about security architecture, they are going to focus on the software life cycle or how to build controls at various application trust boundaries. If you talk to IT operations, they are going to tell you about segmenting the network and hardening the perimeter. To me, security architecture is more holistic: it's the overall set of processes, policy, people, technology, and controls that ensure security goals are aligned with business goals."

– Ted Ipsen, President and COO at Positroniq, LLC

In this chapter, we've discussed what security architecture is conceptually, describing and providing an introduction to some of the standards and frameworks that are involved in effecting it in an organization. The last topic that we will cover before we get into the "meat" of...

Summary

Throughout this chapter, we've attempted to provide you with information about why architecture exists, the value that it provides, and how it is (at a high level) normally practiced throughout enterprises. We've also tried to lay out some of the useful background information about what goes into being a cybersecurity architect.

Looking ahead, we will build on this to unpack the specific processes that architects use to actually do their work and walk through one approach and steps with you that you can use to do so yourself.

In the next chapter, we'll explore governance and why it matters to the security architect; governance structures and their purpose; and learn to cascade from enterprise/mission goals to technology and security goals.

Description

Cybersecurity architects work with others to develop a comprehensive understanding of the business' requirements. They work with stakeholders to plan designs that are implementable, goal-based, and in keeping with the governance strategy of the organization. With this book, you'll explore the fundamentals of cybersecurity architecture: addressing and mitigating risks, designing secure solutions, and communicating with others about security designs. The book outlines strategies that will help you work with execution teams to make your vision a concrete reality, along with covering ways to keep designs relevant over time through ongoing monitoring, maintenance, and continuous improvement. As you progress, you'll also learn about recognized frameworks for building robust designs as well as strategies that you can adopt to create your own designs. By the end of this book, you will have the skills you need to be able to architect solutions with robust security components for your organization, whether they are infrastructure solutions, application solutions, or others.

As a professional in the cybersecurity industry, I have quite the assortment of books and reference material that I constantly turn to for knowledge. This quickly became a favorite in my collection. The methodologies outlined in the book are instructive, intriguing, and helpful in understanding the techniques that modern-day security professionals should keep top of mind. With so many dense and boring cybersecurity reads, the conversational tone of the book really helps in digesting the information provided. If you're in search of a book that covers the concepts, standards, and frameworks that you MUST know in cybersecurity, look no further than this book.

There are so many cybersecurity books and manuals (as alluded to in this book by Moyle and Kelley) that one can read to advance their knowledge. They are, however, often dry and written for someone with either no experience whatsoever, or the expert who doesn't need any background or basic information.This book accomplishes writing to both the novice and the expert, and does so in an interesting, engaging way. Further, it addresses a significant problem in the cybersecurity industry today, this is, the need for thoughtful, careful planning, Having worked in the field for 15+ years, I see enterprise practitioners rushing to implement tools and processes just to be able to check a box. But this is exactly what leads to vulnerabilities.The authors, as promised in the title, lay out a practical approach to architecture based on planning, assessment, and review, from initial stages through execution. Bravo.

The way this book is laid out, it puts together all the components to scope and build a secure architecture. By engineering the network architecture to be reliable, robust and secure, you save money, time, and avoid the regulatory nightmares (when a breach inevitably happens). I love how the authors go beyond the basic building blocks to also discuss soft issues, like finding a champion in your organization to help support the security mission, and talking the talk of business NOT cyber so that the leaders can work with your objectives. So many more nuggets in here. It has all the elements needed for secure architecture in ONE read. Very USEFUL reference guide.

It's great to see a plain language cybersecurity architecture book that can be understood by most IT professionals. Cybersecurity is inherently a complex subject that is ever changing with adoption of new technologies like multi-cloud, Edge computing , AI, and even cryptocurrency. They all require security architecture and this book will give you the background to understand it.

I confess. I got this book as a referral from a friend and colleague – it was a dog-eared copy with quite a few underlined and highlights prior to my read. I always look for the highlights when I respect the colleague. I agree with @Marcos- “The methodologies outlined in the book are instructive, intriguing, and helpful in understanding the techniques that modern-day security professionals should keep top of mind.” This book did further my understanding of the standards in cybersecurity. NOT a long read at 400 pages, but the authors conversational tone allows for a good read. I did add a few highlights of my own to my colleague’s copy – but in a different color highlight. Good writing and great tone added to a quick read of 400 pages.
