The Brewer and Nash model, also known as the Chinese Wall model, is a security model that prevents conflicts of interest. It's used to control access to sensitive information in organizations.
How it works
The model is based on a user's history of accessing data.
It restricts access to related or competing data to prevent conflicts of interest.
It's especially useful in industries where confidential information must be strictly controlled, such as finance or law.
Example
If you access a file from GM, you might be blocked from accessing any files from Ford or Chrysler.
You can access files from companies in any other conflict class.
Uses

It's used to ensure that sensitive information remains confidential.
History
Brewer and Nash introduced the model in 1989.
