Kingdom: Encapsulation
Encapsulation is about drawing strong boundaries. In a web browser that might mean ensuring that your mobile code cannot be abused by other mobile code. On the server it might mean differentiation between validated data and unvalidated data, between one user's data and another's, or between data users are allowed to see and data that they are not.
Android Bad Practices: Encryption Secret Held in Static Field
Abstract
The application holds encryption keys in static class fields, allowing for easy recovery by attackers.
Explanation
Storing encryption keys in static class fields allows easy recovery by an entity that can access the process memory (e.g. rooted device) or process memory dumps (e.g. crash dumps).
