This talk reviews the key technologies available to keep data protected on iStuff, hopefully framing the discussion in a way decision makers can understand. From built-in features, to tricks for getting around them, to advanced attacks, we look at the most important things you can do to keep your data secure. And provide a non-nonsense reality check on the reasons you'll never be 100% safe. We conclude with a short review of best practices, both for configuration and custom application development, as well as a review of improved controls introduced in iOS 6.
