Management and Education of the Risk of Insider Threat (MERIT): Mitigating the Risk of Sabotage to Employers' Information, Systems, or Networks

摘要

The Insider Threat Study, conducted by the U.S. Secret Service and Carnegie Mellon University s Software Engineering Institute CERT Program, analyzed insider cyber crimes across U.S. critical infrastructure sectors. The study indicates that management decisions related to organizational and employee performance sometimes yield unintended consequences that increase risk of insider attack. The problem is exacerbated by a lack of tools for understanding insider threat, analyzing risk mitigation alternatives, and communicating results. The goal of Carnegie Mellon University's Management and Education of the Risk of Insider Threat (MERIT) project is to develop such tools. MERIT uses system dynamics to model and analyze insider threats and produce interactive learning environments. These tools can be used by policy makers, security officers, information technology and human resource personnel, and management. The tools help these users to understand the problem and assess risk from insiders based on simulations of policies, and on cultural, technical, and procedural factors. This technical note describes the MERIT insider threat model and simulation results.
