This document discusses data loss prevention (DLP) concepts and implementations. It begins with an overview of data governance and the data lifecycle. It then defines DLP, explaining how DLP solutions protect data in motion, at rest, and in use. Sample DLP deployments are shown, outlining key activities and considerations for implementation such as governance, infrastructure, and a phased approach. Finally, examples of DLP use cases are provided for data in motion like email and data in use on workstations.
