The Brewer-Nash model is also known as which of the following?

The Brewer-Nash model is commonly referred to as the Chinese Wall model. This model is designed to prevent conflicts of interest by controlling access to sensitive information based on the user's previous access patterns. It is especially relevant in environments such as financial institutions, where an individual may have access to competing parties' sensitive information.

In the Chinese Wall model, users are granted access to data only if they have not previously accessed information that would create a conflict of interest. This approach emphasizes protecting sensitive data while allowing users to access information related to their current project or client, thus maintaining confidentiality and integrity in competitive contexts.

The other options represent different access control models, each with distinct principles and applications, but they do not relate to the Brewer-Nash model's primary focus on managing conflicts of interest in information access.
