Cyber risk quantification involves the application of risk quantification techniques to an organization’s cybersecurity risk. Cyber risk quantification is the process of evaluating the cyber risks that have been identified and then validating, measuring and analyzing the available cyber data using mathematical modeling techniques to accurately represent the organization’s cybersecurity environment in a manner that can be used to make informed cybersecurity infrastructure investment and risk transfer decisions. Cyber risk quantification is a supporting activity to cybersecurity risk management; cybersecurity risk management is a component of enterprise risk management and is especially important in organizations and enterprises that are highly dependent upon their Information Technology (IT) networks and systems for their business operations.
One method of quantifying cyber risk is the Value-at-Risk (VaR) method that is discussed at the January 2015 World Economic Forum meeting (see external reference below). At this meeting, VaR was studied and researched and deemed to be a viable method of quantifying cyber risk.
A metric related to Cyber Risk Quantification that has been identified and cited is "Cyber Risk Reduction Return on Investment" or "CR3OI" as a metric that uses Cyber VaR and is an expression of the return on investment of a single or series of cyber investments. See Cyber Risk Reduction Return on Investment.
