How to Measure Anything in Cybersecurity Risk

By: Douglas W. Hubbard, Richard Seiersen

Overview of this book

How to Measure Anything in Cybersecurity Risk exposes the shortcomings of current “risk management” practices, and offers a series of improvement techniques that help you fill the holes and ramp up security. In his bestselling book How to Measure Anything, author Douglas W. Hubbard opened the business world’s eyes to the critical need for better measurement. This book expands upon that premise and draws from The Failure of Risk Management to sound the alarm in the cybersecurity realm. Some of the field’s premier risk management approaches actually create more risk than they mitigate, and questionable methods have been duplicated across industries and embedded in the products accepted as gospel. This book sheds light on these blatant risks and provides alternate techniques that can help improve your current situation. You’ll also learn which approaches are too risky to save and are actually more damaging than a total lack of any security. Dangerous risk management methods abound; there is no industry more critically in need of solutions than cybersecurity. This book provides solutions where they exist and advises when to change tracks entirely.

Our Path Forward

Part I of this book sets the stage for reasoning about uncertainty in security. We will come to terms on things like security, uncertainty, measurement, and risk management. We also argue against toxic misunderstandings of these terms and why we need a better approach to measuring cybersecurity risk and, for that matter, measuring the performance of cybersecurity risk analysis itself. We will also introduce a very simple quantitative method that could serve as a starting point for anyone, no matter how averse they may be to complexity.

Part II of this book will delve further into evolutionary steps we can take with a very simple quantitative model. We will describe how to add further complexity to a model and how to use even minimal amounts of data to improve those models.

Last, in Part III we will describe what is needed to implement these methods in the organization. We will also talk about the implications of this book for the entire cybersecurity “ecosystem...
