The Brewer and Nash model was constructed to provide information security access controls that can change dynamically. This security model, also known as the Chinese wall model, was designed to provide controls that mitigate conflict of interest in commercial organizations, and is built upon an information flow model.

In the Brewer and Nash model no information can flow between the subjects and objects in a way that would create a conflict of interest.
