- Inheritance
- Classes of objects are created or derived from other object classes. Each derived class inherits the attributes and methods of the prior class. For example, a savings account object can be derived from an account object. The savings account object will automatically have the same attributes and methods.

- Integrated data

Networks, groupware, and products that support dynamic linking are all useful tools to integrate data to make better decisions.

The primary source of danger lies with insiders: employees, ex-employees, partners, or consultants.
