Resilience is defined as the ability to recover from or easily adapt to shocks and stresses. Resilience, unlike the concept of security (which is often and incorrectly conflated with resilience) refers to the system's ability to recover or regenerate its performance after an unexpected impact produces a degradation in its performance. A clear understanding of distinction between security, risk and resilience is important for developing appropriate management of cyber threats. This books draws expertise from academia, industry, and government to present insightful discussion of the fundamental concepts of cyber resilience, including the most current technical issues, relevant methods and procedures, and recent developments of the field. This book offers greater emphasis on applying the concepts and methods of cyber resilience to practical problems as compared to our previous book. The bulk of the material is presented in a logical, consistent, and continuous way that is easily accessible to non-specialists and will be of use as teaching material as well as source of emerging scholarship in the field.
