    Any organization with valuable data has been or will be attacked, probably successfully, at some point and with some damage. And, don't all digitally connected organizations have at least some data that can be considered "valuable"?

    Cyber security is a big, messy, multivariate, multidimensional arena. A reasonable "defense-in-depth" requires many technologies; smart, highly skilled people; and deep and broad analysis, all of which must come together into some sort of functioning whole, which is often termed a security architecture. Secrets of a Cyber Security Architect is about security architecture in practice. Expert security architects have dozens of tricks of their trade in their kips. In this book, author Brook S. E. Schoenfield shares his tips and tricks, as well as myriad tried and true bits of wisdom that his colleagues have shared with him.

    Creating and implementing a cyber security architecture can be hard, complex, and certainly frustrating work. This book is written to ease this pain and show how to express security requirements in ways that make the requirements more palatable and, thus, get them accomplished. It also explains how to surmount individual, team, and organizational resistance. The book covers:

    • What security architecture is and the areas of expertise a security architect needs in practice

    • The relationship between attack methods and the art of building cyber defenses

    • Why to use attacks and how to derive a set of mitigations and defenses

    • Approaches, tricks, and manipulations proven successful for practicing security architecture

    • Starting, maturing, and running effective security architecture programs

    • Secrets of the trade for the practicing security architecture

    • Tricks to surmount typical problems

    Filled with practical insight, Secrets of a Cyber Security Architect is the desk reference every security architect needs to thwart the constant threats and dangers confronting every digitally connected organization.

    Brook S. E. Schoenfield is the author of Securing Systems: Applied Security Architecture and Threat Models and Chapter 9: Applying the SDL Framework to the Real World, in Core Software Security: Security at the Source. He has been published by CRC Press, SANS Institute, Cisco, SAFECode, and the IEEE. Occasionally, he even posts to his security architecture blog, brookschoenfield.com.

    He is the Master Security Architect at a global cyber security consultancy, where he leads the company’s secure design services. He has held security architecture leadership positions at high-tech enterprises for nearly 20 years, at which he has trained and coached hundreds of people in their journey to becoming security architects. Several thousand people have taken his participatory threat modeling classes.

    Brook has presented and taught at conferences such as RSA, BSIMM, OWASP, and SANS What Works Summits on subjects within security architecture, including threat models, DevOps security, information security risk, and other aspects of secure design and software security.

    Brook lives in Montana’s Bitterroot Mountains. When he’s not thinking about, practicing, writing about, and speaking on secure design and software security, he can be found telemark skiing, hiking, and fly fishing in his beloved mountains, exploring new cooking techniques, or playing various genres of guitar—from jazz to percussive fingerstyle.
