How to Measure Anything in Cybersecurity Risk - Hardcover

by Douglas W. Hubbard (Author), Richard Seiersen (Author)

A start-to-finish guide for realistically measuring cybersecurity risk

In the newly revised How to Measure Anything in Cybersecurity Risk, Second Edition, a pioneering information security professional and a leader in quantitative analysis methods delivers yet another eye-opening text applying the quantitative language of risk analysis to cybersecurity. In the book, the authors demonstrate how to quantify uncertainty and shed light on how to measure seemingly intangible goals. It's a practical guide to improving risk assessment with a straightforward and simple framework.

Advanced methods and detailed advice for a variety of use cases round out the book, which also includes:

• A new "Rapid Risk Audit" for a first quick quantitative risk assessment.
• New research on the real impact of reputation damage
• New Bayesian examples for assessing risk with little data
• New material on simple measurement and estimation, pseudo-random number generators, and advice on combining expert opinion

Dispelling long-held beliefs and myths about information security, How to Measure Anything in Cybersecurity Risk is an essential roadmap for IT security managers, CFOs, risk and compliance professionals, and even statisticians looking for novel new ways to apply quantitative techniques to cybersecurity.

In the newly revised Second Edition of How to Measure Anything in Cybersecurity Risk, an experienced information security executive teams with a renowned expert in measurement and decision analysis to deliver another eye-opening text applying the quantitative language of risk analysis to cybersecurity. In the book, the authors explain how to quantify uncertainty and shed light on how to measure apparently intangible objectives. It offers a straightforward and simple framework for improving risk assessment in modern organizations.

This latest edition includes new examples, new modeling methods, new measurement and estimation methods--including new methods for combining expert opinions--and new discussions of the most common objections to the authors' quantitative methods. This includes more Bayesian methods and more on the practical roll-out of a program from ground zero to maturity.

Readers will also find a new "Rapid Risk Audit" to use for an initial and fast quantitative risk assessment and new research on the real impact of reputation damage. You'll learn how to assess risk even when you have access to very little data. Every method and framework described in the book uses the same quantitative language used in real risk assessment and represents a significant improvement over the qualitative approach common in many firms.

An essential roadmap to quantifying and managing cybersecurity risk in contemporary organizations, How to Measure Anything in Cybersecurity Risk is a must-read for IT security managers, CISOs, CFOs, risk managers, and statisticians. It dispels long-standing myths about information security and provides readers with immediately actionable intelligence.
