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.

Actuarial science provides a wellspring of metrics and insights that are invaluable for managing cybersecurity in a business context. Relevant historical data can be obtained from a wide variety of industry and government sources, and combining data from different sources can lead to unexpected, powerful results. We use an actuarial approach to forecast cyber risk in dollar terms and generate a profile showing concentrations of business risk across various dimensions of the enterprise IT infrastructure.

Cyber risk encompasses three broad factors: the at-risk value of assets (particularly data assets), the expected occurrence of different types of cyber incidents, and the expected financial impact of each incident type relative to specific data assets. All three can be estimated by observing long...
