Praise for How to Measure Anything in Cybersecurity Risk
"I am excited to see a new method of risk management emerging from this book. Shifting from purely qualitative judgments and simplifications to a proven quantitative model that leverages measurements and the expertise of security professionals holds the promise for dramatically shifting how we manage cyber risk."
Patrick Heim, head of Trust & Security, Dropbox; former chief trust officer, Salesforce.com
"A refreshing voice of reason in cybersecurity risk management. Richard and Douglas successfully rise above noisy security best practices and flashy methods; practitioners have a lot to gain from the clarity within this book's pages."
Vinnie Liu, partner at Bishop Fox; author of Hacking Exposed; former NSA
"Cybersecurity has become one of the biggest risks facing companies today. There is a need to provide the tools and information for a CISO to become more of a chief information risk officer so they are better able to identify and prioritize risk, allocate resources, and develop effective risk mitigation strategies. This book helps to fill that need."
Steve Katz, the first CISO
"At a time when forecasts tell you a great deal about the forecaster but nothing about the future, comes a practical guide for capturing and articulating risk in the board room with great success."
Tim McKnight, CISO, GE; former CISO, Fidelity
