Security Models

In information security, models provide a way to formalize security policies. Such models can be abstract or intuitive. All models are intended to provide an explicit set of rules that a computer can follow to implement the fundamental security concepts, processes, and procedures that make up a security policy. The models offer a way to deepen your understanding of how a computer operations system should be designed and developed to support a specific security policy. No system can be totally secure; security professionals have several security models to consider. 

Let's say you work for one of the following types of industry:

Manufacturing
