Danger! Danger! Your Mobile Applications Are Not Secure

Johannes Ullrich, SANS Technology Institute

A new breed of mobile devices with sophisticated processors and ample storage has given rise to sophisticated applications that move more and more data and business logic to devices. The result is significant and potentially dangerous security challenges, especially for location-aware mobile applications and those storing sensitive or valuable data on devices. To counter these risks, Johannes Ullrich introduces and demonstrates design strategies you can use to mitigate these risks and make applications safer and less vulnerable. Johannes illustrates design patterns to: co-validate data on both the client and server; authenticate transactions on the server; and store only authenticated and access-controlled data on the client. Learn to apply these solutions without losing access to powerful HTML5 JavaScript APIs such as those required for location-based mobile applications. Johannes shares the source code of a location-based mobile application used to organize the cataloging of historic buildings.
