As data accumulates as a part of U.S. Government Insider Threat (InT) initiatives, fundamental knowledge in research design and statistical principles, along with data governance and analytical capabilities, are required to effectively manage and analyze such data. At the programmatic level, data analysis can be used to evaluate the capabilities, effectiveness, feasibility, and costs of proposed and alternative programs under consideration. To strengthen the InT community’s ability to identify and improve prevention and response efforts, the Office of the Under Secretary of Defense for Intelligence and Security funded the Defense Personnel and Security Research Center’s Threat Lab to develop a data and analysis Workbook for use by the InT community. The purpose of this Research Note is to document the workbook development process.
