Description

Draw strong boundaries among application elements, including modules, functions and data, to limit the impact of potential attacks.

Design
- Separate internal administrator's functions from external users' functions
- Differentiate 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.
- In a web browser ensure that your mobile code cannot be abused by other mobile code.
Implementation
- Hide internal details of a class, including data and methods, using private access modifier.
