Identifying vulnerabilities and critical requirements using criminal court proceedings.

Information systems governed by laws and regulations are subject to civil and criminal violations. In the United States, these violations are documented in court records, such as complaints, indictments, plea agreements, and verdicts, which thus constitute a source of real-world software vulnerabilities. This paper reports on an exploratory case study to identify legal vulnerabilities and provides guidance to practitioners in the analysis of court documents. As legal violations occur after system deployment, court records reveal vulnerabilities that were likely overlooked during software development. We evaluate established requirements engineering techniques, including sequence and misuse case diagrams and goal models, as applied to criminal court records to identify mitigating requirements that improve privacy protections. These techniques, when properly applied, can help organizations focus their risk-management efforts on emerging legal vulnerabilities. We illustrate our analysis using criminal indictments involving the U.S. Health Insurance Portability and Accountability Act (HIPAA).
