Establishing a new framework for understanding insider risk by focusing on systems of organization within large enterprises, including public, private and not-for-profit sectors, this book analyses practices to better assess, prevent, detect, and respond to insider risk and protect assets and public good. Analysing case studies from around the world, the book includes real-world insider threat scenarios to illustrate the outlined framework in the application, as well as to assist accountable entities within organizations to implement the changes required to embed the framework into normal business practices. Based on information, data, applied research and empirical study undertaken over ten years, across a broad range of government departments and agencies in various countries, the framework presented provides a more accurate and systemic method to identifying insider risk, as well as enhanced and cost-effective approaches to investing in prevention, detection and response controls and measuring the impact of controls on risk management and financial or other loss. Managing Insider Risk will be of great interest to scholars and students studying white-collar crime, criminal law, public policy and criminology, transnational crime, national security, financial management, international business, and risk management.
