Those of us who work with sensitive data are likely familiar with Esri’s Trust site (trust.arcgis) for security alerts, announcements, articles, and training. They recently uploaded a whitepaper, ArcGIS Secure Mobile Implementation Patterns, that provides some helpful guidelines for working with sensitive data on mobile devices. The paper is not a step-by-step how-to doc, but is intended to provide users with background, tips, and guidance.
