What this book covers
Chapter 1, Introduction to Cybersecurity, provides foundational concepts and basics to understanding the concepts of cybersecurity and, ultimately, how that plays into the role of the cybersecurity architect. This will provide a foundational level setting for those new to cybersecurity while also providing a fundamental refresher to those who have been working within cybersecurity or IT for some time.
Chapter 2, Cybersecurity Foundation, continues on from the introduction to get a bit more granular from a foundational level to discuss some of the main areas that a cybersecurity architect will need to address and understand as it relates to the business and other operational teams. This will be cursory in nature but provides the foundational aspects to progress into the discussion of the cybersecurity career path and the options available to the potential cybersecurity architect in specializing/focusing in a particular area.
Chapter 3, What Is a Cybersecurity Architect and What Are Their Responsibilities?, begins with the principle that you have enough understanding of cybersecurity to discuss the role of the cybersecurity architect and how it builds upon other technology roles. Whether that is in the area of enterprise, application, network, or platform architecture, these areas have differing focuses that span everything to a specific subset. This is also in context with the organization and technology. Once the framework of the architect is defined, the responsibilities become more evident, as it relates to the specific area of focus or organization.
Chapter 4, Cybersecurity Architecture Principles, Design, and Analysis, provides foundational concepts for cybersecurity architecture, including principles, design, and analysis. It emphasizes using clear terminology and outlining organizational goals and risk tolerance as critical inputs that shape architecture.
Chapter 5, Threat, Risk, and Governance Considerations as an Architect, discusses the areas of architecture principles, design, and analysis that will be part of the day-to-day functions of the cybersecurity architect. This will discuss the various approaches to performing the design and analysis of a particular solution or control with an understanding of the principles around the choice one would take over another depending on the situation.
Chapter 6, Documentation as a Cybersecurity Architect - Valuable Resources and Guidance for a Cybersecurity Architect Role, takes somewhat of a break from the more detailed concepts to discuss the importance of proper documentation as it relates to the cybersecurity architect role. This will discuss the need for granularity and a detailed approach to documentation through tools such as Microsoft Visio or DrawIO and other similar tools. There will also be a discussion of how to document and/or create scratchpads for notes through tools such as CherryTree. All of this is meant to help propel the visibility of solutioning and architecture design not only within the organization but also for regulatory and compliance requirements.
Chapter 7, Entry-Level-to-Architect Roadmap, discusses the journey to get to the top as a cybersecurity architect. It goes without saying that certain career paths are more direct than others for the cybersecurity architect. Like most things in technology, "it depends" can be a common answer. This chapter provides various approaches to gaining the experience or skill set to become a cybersecurity architect. Whether that is starting as an IT technician or transitioning from a developer, there are commonalities or skills that need to be gained or used to help shape the path for this career path.
Chapter 8, The Certification Dilemma, discusses a number of certifications for security architecture, as well as others to help differentiate yourself from others who are competing for the same position. It also discusses the good, bad, and ugly of the certification process and how to make the choices that will best match your overall career plan and direction.
Chapter 9, Decluttering the Toolset - Part 1, explores strategies for cybersecurity architects to thoughtfully assemble their security toolkit by evaluating solutions to find the optimal fit for their organization's specific threat landscape, business needs, and operational constraints. It provides an overview of major security tool categories such as threat modeling, network monitoring, endpoint protection, identity access management, data encryption, vulnerability management, and more. The chapter emphasizes matching defenses to an organization's unique vulnerabilities and risks rather than a one-size-fits-all approach.
Chapter 10, Decluttering the Toolset - Part 2, emphasizes the importance of thoughtfully selecting cybersecurity tools tailored to an organization's unique vulnerabilities, infrastructure, and strategic objectives. It advises taking a methodical approach to identifying specific security gaps and requirements first before assessing tools. Tight alignment with frameworks such as NIST CSF, implementing layered defenses, weighing business factors such as cost and usability, and future-proofing selections are highlighted as critical to building an optimal toolkit.
Chapter 11, Best Practices, goes into detail about best practices, as it relates to cybersecurity and why it is best to implement solutions using best practices. This includes the use of standards or technology-specific best practices. The chapter will also discuss when one may supersede another and why you may be faced with that scenario.
Chapter 12, Being Adaptable as a Cybersecurity Architect, explores how architects can cultivate personal and professional adaptability to implement pragmatic solutions tailored to unique business environments and goals. It builds on previous core concepts to underscore why rigid adherence to...
