CRS – Data Security and Breach Notification Legislation: Selected Legal Issues, Alissa M. Dolan, Legislative Attorney. December 28, 2015. “Recent data breaches at major U.S. retailers have placed a spotlight on concerns about the security of personal information stored in electronic form by corporations and other private entities. A data breach occurs when data containing sensitive personal information is lost, stolen, or accessed in an unauthorized manner, thereby causing a potential compromise of the confidentiality of the data. Existing federal laws, such as the Health Insurance Portability and Accountability Act (HIPAA), the Health Information Technology for Economic and Clinical Health Act (HITECH Act), and the Gramm-Leach-Bliley Act, impose security and breach notification requirements on specific industries or types of data. Additionally, 47 states, the District of Columbia (D.C.), and three territories have enacted laws requiring breach notification, while at least 12 states have enacted data security laws, designed to reduce the likelihood of a data breach. Alabama, New Mexico, and South Dakota have not enacted breach notification laws.”
