A Performance Assessment Metric for Information Security Financial Instruments
Business interruptions caused by cyber-attacks pose a serious threat to revenue and share price of the organisation. Furthermore, recent cyber-attacks on various organisations prove that the technical controls, security policies, and regulatory compliance are not sufficient to mitigate the cyber risks. In such a scenario, the residual cyber risk can be mitigated with cyber-insurance policies and with information security derivatives (financial instruments). Information security derivatives are a new class of financial instruments designed to provide an alternate risk mitigation mechanism to reduce the potential adverse impact of an information security event. However, there is a lack of research on the metrics to measure the performance of information security derivatives in mitigating the underlying risk. This article examines the basic requirements to assess the performance of information security derivatives. Furthermore, the article presents three metrics, namely hedge ratio, hedge effectiveness, and hedge efficiency to formulate and evaluate a cyber risk mitigation strategy devised with information security derivatives. Also, the application of these metrics is demonstrated in an imaginary scenario. The accurate measure of performance of information security derivatives is of practical importance for effective risk management strategy.
