Cyber Risk Measurement and Management: An Introduction to Cybernomics examines the indispensable role of economic modeling in the future of digitization, thus providing industry professionals with the tools they need to optimize the management of financial risks associated with this mega trend. The book addresses three problem areas: the valuation of digital assets, quantification of risk exposures of digital valuables, and economic modeling for the management of such risks. Employing a novel cyber risk measurement unit, the book includes value, risk, control and cost, each of which are viewed from the perspective of entity, portfolio and global ramifications.

Key Features
